Update to v098r04 release. byuu says: Changelog: - SFC: fixed behavior of 21fx $21fe register when no device is connected (must return zero) - SFC: reduced 21fx buffer size to 1024 bytes in both directions to mirror the FT232H we are using - SFC: eliminated dsp/modulo-array.hpp [1] - higan: implemented higan/video interface and migrated all cores to it [2] [1] the echo history buffer was 8-bytes, so there was no need for it at all here. Not sure what I was thinking. The BRR buffer was 12-bytes, and has very weird behavior ... but there's only a single location in the code where it actually writes to this buffer. It's much easier to just write to the buffer three times there instead of implementing an entire class just to abstract away two lines of code. This change actually boosted the speed from ~124.5fps to around ~127.5fps, but that's within the margin of error for GCC. I doubt it's actually faster this way. The DSP core could really use a ton of work. It comes from a port of blargg's spc_dsp to my coding style, but he was extremely fond of using 32-bit signed integers everywhere. There's a lot of opportunity to remove red tape masking by resizing the variables to their actual state sizes. I really need to find where I put spc_dsp6.sfc from blargg. It's a great test to verify if I've made any mistakes in my implementation that would cause regressions. Don't suppose anyone has it? [2] so again, the idea is that higan/audio and higan/video are going to sit between the emulation cores and the user interfaces. The hope is to output raw encoding data from the emulation cores without having to worry about the video display format (generally 24-bit RGB) of the host display. And also to avoid having to repeat myself with eg three separate implementations of interframe blending, and so on. Furthermore, the idea is that the user interface can configure its side of the settings, and the emulation cores can configure their sides. Thus, neither has to worry about the other end. And now we can spin off new user interfaces much easier without having to mess with all of these things. Right now, I've implemented color emulation, interframe blending and SNES horizontal color bleed. I did not implement scanlines (and interlace effects for them) yet, but I probably will at some point. Further, for right now, the WonderSwan/Color screen rotation is busted and will only show games in the horizontal orientation. Obviously this must be fixed before the next official release, but I'll want to think about how to implement it. Also, the SNES light gun pointers are missing for now. Things are a bit messy right now as I've gone through several revisions of how to handle these things, so a good house cleaning is in order once everything is feature-complete again. I need to sit down and think through how and where I want to handle things like light gun cursors, LCD icons, and maybe even rasterized text messages. And obviously ... higan/audio is still just nall::DSP's headers. I need to revamp that whole interface. I want to make it quite powerful with a true audio mixer so I can handle things like SNES+SGB+MSU1+Voicer-Kun+SNES-CD (five separate audio streams at once.) The video system has the concept of "effects" for things like color bleed and interframe blending. I want to extend on this with useful other effects, such as NTSC simulation, maybe bringing back my mini-HQ2x filter, etc. I'd also like to restore the saturation/gamma/luma adjustment sliders ... I always liked allowing people to compensate for their displays without having to change settings system-wide. Lastly, I've always wanted to see some audio effects. Although I doubt we'll ever get my dream of CoreAudio-style profiles, I'd like to get some basic equalizer settings and echo/reverb effects in there.

#include "video.cpp"
Update to v098r03 release. byuu says: It took several hours, but I've rebuilt much of the SNES' bus memory mapping architecture. The new design unifies the cartridge string-based mapping ("00-3f,80-bf:8000-ffff") and internal bus.map calls. The map() function now has an accompanying unmap() function, and instead of a fixed 256 callbacks, it'll scan to find the first available slot. unmap() will free slots up when zero addresses reference a given slot. The controllers and expansion port are now both entirely dynamic. Instead of load/unload/power/reset, they only have the constructor (power/reset/load) and destructor (unload). What this means is you can now dynamically change even expansion port devices after the system is loaded. Note that this is incredibly dangerous and stupid, but ... oh well. The whole point of this was for 21fx. There's no way to change the expansion port device prior to loading a game, but if the 21fx isn't active, then the reset vector hijack won't work. Now you can load a 21fx game, change the expansion port device, and simply reset the system to active the device. The unification of design between controller port devices and expansion port devices is nice, and overall this results in a reduction of code (all of the Mapping stuff in Cartridge is gone, replaced with direct bus mapping.) And there's always the potential to expand this system more in the future now. The big missing feature right now is the ability to push/pop mappings. So if you look at how the 21fx does the reset vector, you might vomit a little bit. But ... it works. Also changed exit(0) to _exit(0) in the POSIX version of nall::execute. [The _exit(0) thing is an attempt to make higan not crash when it tries to launch icarus and it's not on $PATH. The theory is that higan forks, then the child tries to exec icarus and fails, so it exits, all the unique_ptrs clean up their resources and tell the X server to free things the parent process is still using. Calling _exit() prevents destructors from running, and seems to prevent the problem. -Ed.]

Update to v100r14 release. byuu says: (Windows: compile with -fpermissive to silence an annoying error. I'll fix it in the next WIP.) I completely replaced the time management system in higan and overhauled the scheduler. Before, processor threads would have "int64 clock"; and there would be a 1:1 relationship between two threads. When thread A ran for X cycles, it'd subtract X * B.Frequency from clock; and when thread B ran for Y cycles, it'd add Y * A.Frequency from clock. This worked well and allowed perfect precision; but it doesn't work when you have more complicated relationships: eg the 68K can sync to the Z80 and PSG; the Z80 to the 68K and PSG; so the PSG needs two counters. The new system instead uses a "uint64 clock" variable that represents time in attoseconds. Every time the scheduler exits, it subtracts the smallest clock count from all threads, to prevent an overflow scenario. The only real downside is that rounding errors mean that roughly every 20 minutes, we have a rounding error of one clock cycle (one 20,000,000th of a second.) However, this only applies to systems with multiple oscillators, like the SNES. And when you're in that situation ... there's no such thing as a perfect oscillator anyway. A real SNES will be thousands of times less out of spec than 1hz per 20 minutes. The advantages are pretty immense. First, we obviously can now support more complex relationships between threads. Second, we can build a much more abstracted scheduler. All of libco is now abstracted away completely, which may permit a state-machine / coroutine version of Thread in the future. We've basically gone from this: auto SMP::step(uint clocks) -> void { clock += clocks * (uint64)cpu.frequency; dsp.clock -= clocks; if(dsp.clock < 0 && !scheduler.synchronizing()) co_switch(dsp.thread); if(clock >= 0 && !scheduler.synchronizing()) co_switch(cpu.thread); } To this: auto SMP::step(uint clocks) -> void { Thread::step(clocks); synchronize(dsp); synchronize(cpu); } As you can see, we don't have to do multiple clock adjustments anymore. This is a huge win for the SNES CPU that had to update the SMP, DSP, all peripherals and all coprocessors. Likewise, we don't have to synchronize all coprocessors when one runs, now we can just synchronize the active one to the CPU. Third, when changing the frequencies of threads (think SGB speed setting modes, GBC double-speed mode, etc), it no longer causes the "int64 clock" value to be erroneous. Fourth, this results in a fairly decent speedup, mostly across the board. Aside from the GBA being mostly a wash (for unknown reasons), it's about an 8% - 12% speedup in every other emulation core. Now, all of this said ... this was an unbelievably massive change, so ... you know what that means >_> If anyone can help test all types of SNES coprocessors, and some other system games, it'd be appreciated. ---- Lastly, we have a bitchin' new about screen. It unfortunately adds ~200KiB onto the binary size, because the PNG->C++ header file transformation doesn't compress very well, and I want to keep the original resource files in with the higan archive. I might try some things to work around this file size increase in the future, but for now ... yeah, slightly larger archive sizes, sorry. The logo's a bit busted on Windows (the Label control's background transparency and alignment settings aren't working), but works well on GTK. I'll have to fix Windows before the next official release. For now, look on my Twitter feed if you want to see what it's supposed to look like. ---- EDIT: forgot about ICD2::Enter. It's doing some weird inverse run-to-save thing that I need to implement support for somehow. So, save states on the SGB core probably won't work with this WIP.

Update to v091r05 release. [No prior releases were posted to the WIP thread. -Ed.] byuu says: Super Famicom mapping system has been reworked as discussed with the mask= changes. offset becomes base, mode is gone. Also added support for comma-separated fields in the address fields, to reduce the number of map lines needed. <?xml version="1.0" encoding="UTF-8"?> <cartridge region="NTSC"> <superfx revision="2"> <rom name="program.rom" size="0x200000"/> <ram name="save.rwm" size="0x8000"/> <map id="io" address="00-3f,80-bf:3000-32ff"/> <map id="rom" address="00-3f:8000-ffff" mask="0x8000"/> <map id="rom" address="40-5f:0000-ffff"/> <map id="ram" address="00-3f,80-bf:6000-7fff" size="0x2000"/> <map id="ram" address="70-71:0000-ffff"/> </superfx> </cartridge> Or in BML: cartridge region=NTSC superfx revision=2 rom name=program.rom size=0x200000 ram name=save.rwm size=0x8000 map id=io address=00-3f,80-bf:3000-32ff map id=rom address=00-3f:8000-ffff mask=0x8000 map id=rom address=40-5f:0000-ffff map id=ram address=00-3f,80-bf:6000-7fff size=0x2000 map id=ram address=70-71:0000-ffff As a result of the changes, old mappings will no longer work. The above XML example will run Super Mario World 2: Yoshi's Island. Otherwise, you'll have to write your own. All that's left now is to work some sort of database mapping system in, so I can start dumping carts en masse. The NES changes that FitzRoy asked for are mostly in as well. Also, part of the reason I haven't released a WIP ... but fuck it, I'm not going to wait forever to post a new WIP. I've added a skeleton driver to emulate Campus Challenge '92 and Powerfest '94. There's no actual emulation, except for the stuff I can glean from looking at the pictures of the board. It has a DSP-1 (so SR/DR registers), four ROMs that map in and out, RAM, etc. I've also added preliminary mapping to upload high scores to a website, but obviously I need the ROMs first.

Update to v099r06 release. byuu says: Changelog: - Super Famicom core converted to use nall/vfs - excludes Super Game Boy; since that's invoked from inside the GB core This was definitely the major obstacle to test nall/vfs' applicability. Things worked out pretty great in the end. We went from 22.0KiB (cartridge) + 18.6KiB (interface) to 24.5KiB (cartridge) + 11.4KiB (interface). Or 40.7KiB to 36.0KiB. This removes a very large source of indirection. Before it was: "coprocessor <=> cartridge <=> interface" for loading and saving data, and now it's just "coprocessor <=> cartridge". And it may make sense to eventually turn this into just "cartridge -> coprocessor" by making each coprocessor class handle its own markup parsing. It's nice to have all the manifest parsing in one location (well, sans MSU1); but it's also nice for loading/unloading to be handled by each coprocessor itself. So I'll have to think longer about that one. I've also started handling Interface::save() differently. Instead of keeping track of memory IDs and filenames, and iterating through that vector of objects ... instead I now have a system that mirrors the markup parsing on loading, but handles saving instead. This was actually the reason the code size savings weren't more significant, but I like this style more. As before, it removes an extra level of indirection. So ... next up, I need to port over the GB, then GBA, then WS cores. These shouldn't take too long since they're all very simple with just ROM+RAM(+RTC) right now. Then get the SGB callbacks using vfs. Then after that, gut all the old stream stuff from nall and higan. Kill the (load,save)Request stuff, rename the load(Gamepak)Request to something simpler, and then we should be good. Anyway ... these are some huge changes.

Update to v094r39 release. byuu says: Changelog: - SNES mid-scanline BGMODE fixes finally merged (can run atx2.zip{mode7.smc}+mtest(2).sfc properly now) - Makefile now discards all built-in rules and variables - switch on bool warning disabled for GCC now as well (was already disabled for Clang) - when loading a game, if any required files are missing, display a warning message box (manifest.bml, program.rom, bios.rom, etc) - when loading a game (or a game slot), if manifest.bml is missing, it will invoke icarus to try and generate it - if that fails (icarus is missing or the folder is bad), you will get a warning telling you that the manifest can't be loaded The warning prompt on missing files work for both games and the .sys folders and their files. For some reason, failing to load the DMG/CGB BIOS is causing a crash before I can display the modal dialog. I have no idea why, and the stack frame backtrace is junk. I also can't seem to abort the failed loading process. If I call Program::unloadMedia(), I get a nasty segfault. Again with a really nasty stack trace. So for now, it'll just end up sitting there emulating an empty ROM (solid black screen.) In time, I'd like to fix that too. Lastly, I need a better method than popen for Windows. popen is kind of ugly and flashes a console window for a brief second even if the application launched is linked with -mwindows. Not sure if there even is one (I need to read the stdout result, so CreateProcess may not work unless I do something nasty like "> %tmp%/temp") I'm also using the regular popen instead of _wpopen, so for this WIP, it won't work if your game folder has non-English letters in the path.

Update to v099r08 release. byuu says: Changelog: - nall/vfs work 100% completed; even SGB games load now - emulation cores now call load() for the base cartridges as well - updated port/device handling; portmask is gone; device ID bug should be resolved now - SNES controller port 1 multitap option was removed - added support for 128KiB SNES PPU VRAM (for now, edit sfc/ppu/ppu.hpp VRAM::size=0x10000; to enable) Overall, nall/vfs was a huge success!! We've substantially reduced the amount of boilerplate code everywhere, while still allowing (even easier than before) support for RAM-based game loading/saving. All of nall/stream is dead and buried. I am considering removing Emulator::Interface::Medium::id and/or bootable flag. Or at least, doing something different with it. The values for the non-bootable GB/BS/ST entries duplicate the ID that is supposed to be unique. They are for GB/GBC and WS/WSC. Maybe I'll use this as the hardware revision selection ID, and then gut non-bootable options. There's really no reason for that to be there. I think at one point I was using it to generate library tabs for non-bootable systems, but we don't do that anymore anyway. Emulator::Interface::load() may not need the required flag anymore ... it doesn't really do anything right now anyway. I have a few reasons for having the cores load the base cartridge. Most importantly, it is going to enable a special mode for the WonderSwan / WonderSwan Color in the future. If we ever get the IPLROMs dumped ... it's possible to boot these systems with no games inserted to set user profile information and such. There are also other systems that may accept being booted without a cartridge. To reach this state, you would load a game and then cancel the load dialog. Right now, this results in games not loading. The second reason is this prevents nasty crashes when loading fails. So if you're missing a required manifest, the emulator won't die a violent death anymore. It's able to back out at any point. The third reason is consistency: loading the base cartridge works the same as the slot cartridges. The fourth reason is Emulator::Interface::open(uint pathID) values. Before, the GB, SB, GBC modes were IDs 1,2,3 respectively. This complicated things because you had to pass the correct ID. But now instead, Emulator::Interface::load() returns maybe<uint> that is nothing when no game is selected, and a pathID for a valid game. And now open() can take this ID to access this game's folder contents. The downside, which is temporary, is that command-line loading is currently broken. But I do intend on restoring it. In fact, I want to do better than before and allow multi-cart booting from the command-line by specifying the base cartridge and then slot cartridges. The idea should be pretty simple: keep a queue of pending filenames that we fill from the command-line and/or drag-and-drop operations on the main window, and then empty out the queue or prompt for load dialogs from the UI when booting a system. This also might be a bit more unorthodox compared to the traditional emulator design of "loadGame(filename)", but ... oh well. It's easy enough still. The port/device changes are fun. We simplified things quite a bit. The portmask stuff is gone entirely. While ports and devices keep IDs, this is really just sugar-coating so UIs can use for(auto& port : emulator->ports) and access port.id; rather than having to use for(auto n : range(emulator->ports)) { auto& port = emulator->ports[n]; ... }; but they should otherwise generally be identical to the order they appear in their respective ranges. Still, don't rely on that. Input::id is gone. There was no point since we also got rid of the nasty Input::order vector. Since I was in here, I went ahead and caved on the pedantics and renamed Input::guid to Input::userData. I removed the SNES controller port 1 multitap option. Basically, the only game that uses this is N-warp Daisakusen and, no offense to d4s, it's not really a good game anyway. It's just a quick demo to show 8-players on the SNES. But in the UI, all it does is confuse people into wasting time mapping a controller they're never going to use, and they're going to wonder which port to use. If more compelling use cases for 8-players comes about, we can reconsider this. I left all the code to support this in place, so all you have to do is uncomment one line to enable it again. We now have dsnes emulation! :D If you change PPU::VRAM::size to 0x10000 (words), then you should now have 128KiB of VRAM. Even better, it serializes the used-VRAM size, so your save states shouldn't crash on you if you swap between the two (though if you try this, you're nuts.) Note that this option does break commercial software. Yoshi's Island in particular. This game is setting A15 on some PPU register writes, but not on others. The end result of this is things break horribly in-game. Also, this option is causing a very tiny speed hit for obvious reasons with the variable masking value (I'm even using size-1 for now.) Given how niche this is, I may just leave it a compile-time constant to avoid the overhead cost. Otherwise, if we keep the option, then it'll go into Super Famicom.sys/manifest.bml ... I'll flesh that out in the near-future. ---- Finally, some fun for my OCD ... my monitor suddenly cut out on me in the middle of working on this WIP, about six hours in of non-stop work. Had to hit a bunch of ctrl+alt+fN commands (among other things) and trying to log in headless on another TTY to do issue commands, trying to recover the display. Finally power cycled the monitor and it came back up. So all my typing ended up going to who knows where. Usually this sort of thing terrifies me enough that I scrap a WIP and start over to ensure I didn't screw anything up during the crashed screen when hitting keys randomly. Obviously, everything compiles and appears to work fine. And I know it's extremely paranoid, but OCD isn't logical, so ... I'm going to go over every line of the 100KiB r07->r08 diff looking for any corruption/errors/whatever. ---- Review finished. r08 diff review notes: - fc/controller/gamepad/gamepad.cpp: use uint device = ID::Device::Gamepad; not id = ...; - gb/cartridge/cartridge.hpp: remove redundant uint _pathID; (in Information::pathID already) - gb/cartridge/cartridge.hpp: pull sha256 inside Information - sfc/cartridge/load/cpp: add " - Slot (A,B)" to interface->load("Sufami Turbo"); to be more descriptive - sfc/controller/gamepad/gamepad.cpp: use uint device = ID::Device::Gamepad; not id = ...; - sfc/interface/interface.cpp: remove n variable from the Multitap device input generation loop (now unused) - sfc/interface/interface.hpp: put struct Port above struct Device like the other classes - ui-tomoko: cheats.bml is reading from/writing to mediumPaths(0) [system folder instead of game folder] - ui-tomoko: instead of mediumPaths(1) - call emulator->metadataPathID() or something like that

Update to v097r12 release. byuu says: Nothing WS-related this time. First, I fixed expansion port device mapping. On first load, it was mapping the expansion port device too late, so it ended up not taking effect. I had to spin out the logic for that into Program::connectDevices(). This was proving to be quite annoying while testing eBoot (SNES-Hook simulation.) Second, I fixed the audio->set(Frequency, Latency) functions to take (uint) parameters from the configuration file, so the weird behavior around changing settings in the audio panel should hopefully be gone now. Third, I rewrote the interface->load,unload functions to call into the (Emulator)::System::load,unload functions. And I have those call out to Cartridge::load,unload. Before, this was inverted, and Cartridge::load() was invoking System::load(), which I felt was kind of backward. The Super Game Boy really didn't like this change, however. And it took me a few hours to power through it. Before, I had the Game Boy core dummying out all the interface->(load,save)Request calls, and having the SNES core make them for it. This is because the folder paths and IDs will be different between the two cores. I've redesigned things so that ICD2's Emulator::Interface overloads loadRequest and saveRequest, and translates the requests into new requests for the SuperFamicom core. This allows the Game Boy code to do its own loading for everything without a bunch of Super Game Boy special casing, and without any awkwardness around powering on with no cartridge inserted. This also lets the SNES side of things simply call into higher-level GameBoy::interface->load,save(id, stream) functions instead of stabbing at the raw underlying state inside of various Game Boy core emulation classes. So things are a lot better abstracted now.

Update to v098r03 release. byuu says: It took several hours, but I've rebuilt much of the SNES' bus memory mapping architecture. The new design unifies the cartridge string-based mapping ("00-3f,80-bf:8000-ffff") and internal bus.map calls. The map() function now has an accompanying unmap() function, and instead of a fixed 256 callbacks, it'll scan to find the first available slot. unmap() will free slots up when zero addresses reference a given slot. The controllers and expansion port are now both entirely dynamic. Instead of load/unload/power/reset, they only have the constructor (power/reset/load) and destructor (unload). What this means is you can now dynamically change even expansion port devices after the system is loaded. Note that this is incredibly dangerous and stupid, but ... oh well. The whole point of this was for 21fx. There's no way to change the expansion port device prior to loading a game, but if the 21fx isn't active, then the reset vector hijack won't work. Now you can load a 21fx game, change the expansion port device, and simply reset the system to active the device. The unification of design between controller port devices and expansion port devices is nice, and overall this results in a reduction of code (all of the Mapping stuff in Cartridge is gone, replaced with direct bus mapping.) And there's always the potential to expand this system more in the future now. The big missing feature right now is the ability to push/pop mappings. So if you look at how the 21fx does the reset vector, you might vomit a little bit. But ... it works. Also changed exit(0) to _exit(0) in the POSIX version of nall::execute. [The _exit(0) thing is an attempt to make higan not crash when it tries to launch icarus and it's not on $PATH. The theory is that higan forks, then the child tries to exec icarus and fails, so it exits, all the unique_ptrs clean up their resources and tell the X server to free things the parent process is still using. Calling _exit() prevents destructors from running, and seems to prevent the problem. -Ed.]

Update to v074r10 release. byuu says: Major WIP, countless changes. I really went to town on cleaning up the source today with all kinds of new ideas. I'll post the ones I remember, use diff -ru to get the rest. What I like the most is my new within template: template<unsigned lo, unsigned hi> alwaysinline bool within(unsigned addr) { static const unsigned mask = ~(hi ^ lo); return (addr & mask) == lo; } Before, you would see code like this: if((addr & 0xe0e000) == 0x206000) { //$20-3f:6000-7fff The comment is basically necessary, and you have to trust that the mask is right, or do the math yourself. Now, it looks like this: if(within<0x20, 0x3f, 0x6000, 0x7fff>(addr)) { That's the same as within<0x206000, 0x3f7fff>, I just made an SNES-variant to more closely simulate my XML mapping style: 20-3f:6000-7fff. Now obviously this has limitations, it only works in base-2 and it can't manage some tricky edge cases like (addr & 0x408000) == 0x008000 for 00-3f|80-bf:8000-ffff. But for the most part, I'll be using this where I can. The Game Boy is fully ported over to it (via the MBCs), but the SNES only has the BS-X town cartridge moved over so far. SuperFX and SA-1 at the very least could benefit. Next up, since the memory map is now static, there's really no reason to remap the entire thing at power-on and reset. So it is now set up at cartridge load and that's it. I moved the CPU/PPU/WRAM mapping out of memory.cpp and into their respective processors. A bit of duplication only because there are multiple processor cores for the different profiles, but I'm not worried about that. This is also going to be necessary to fix the debugger. Next, Coprocessor::enable() actually does what I initially intended it to now: it is called once to turn a chip on after cartridge load. It's not called on power cycle anymore. This should help fix power-cycle on my serial simulation code, and was needed to map the bus exactly one time. Although most stuff is mapped through XML, some chips still need some manual hooks for monitoring and such (eg S-DD1.) Next, I've started killing off memory::, it was initially an over-reaction to the question of where to put APURAM (in the SMP or DSP?). The idea was to have this namespace that contained all memory for everything. But it was very annoying and tedious, and various chips ignored the convention anyway like ST-0011 RAM, which couldn't work anyway since it is natively uint16 and not uint8. Cx4 will need 24-bit RAM eventually, too. There's 8->24-bit functions in there now, because the HLE code is hideous. So far, all the cartridge.cpp memory:: types have been destroyed. memory::cartrom, memory::cartram become cartridge.rom and cartridge.ram. memory::cartrtc was moved into the SRTC and SPC7110 classes directly. memory::bsxflash was moved into BSXFlash. memory::bsxram and memory::bsxpram were moved into BSXCartridge (the town cartridge). memory::st[AB](rom|ram) were moved into a new area, snes/chip/sufamiturbo. The snes/chip moniker really doesn't work so well, since it also has base units, and the serial communications stuff which is through the controller port, but oh well, now it also has the base structure for the Sufami Turbo cartridge too. So now we have sufamiturbo.slotA.rom, sufamiturbo.slotB.ram, etc. Next, the ST-0010/ST-0011 actually save the data RAM to disk. This wasn't at all compatible with my old system, and I didn't want to keep adding memory types to check inside the main UI cartridge RAM loading and saving routines. So I built a NonVolatileRAM vector inside SNES::Cartridge, and any chip that has memory it wants to save and load from disk can append onto it : data, size, id ("srm", "rtc", "nec", etc) and slot (0 = cartridge, 1 = slot A, 2 = slot B) To load and save memory, we just do a simple: foreach(memory, SNES::cartridge.nvram) load/saveMemory(memory). As a result, you can now keep your save games in F1 Race of Champions II and Hayazashi Nidan Morita Shougi. Technically I think Metal Combat should work this way as well, having the RAM being part of the chip itself, but for now that chip just writes directly into cartridge.ram, so it also technically saves to disk for now. To avoid a potential conflict with a manipulated memory map, BS-X SRAM and PSRAM are now .bss and .bsp, and not .srm and .psr. Honestly I don't like .srm as an extension either, but it doesn't bother me enough to break save RAM compatibility with other emulators, so don't worry about that changing. I finally killed off MappedRAM initializing size to ~0 (-1U). A size of zero means there is no memory there just the same. This was an old holdover for handling MMIO mapping, if I recall correctly. Something about a size of zero on MMIO-Memory objects causing it to wrap the address, so ~0 would let it map direct addresses ... or something. Whatever, that's not needed at all anymore. BSXBase becomes BSXSatellaview, and I've defaulted the device to being attached since it won't affect non-BSX games anyway. Eventually the GUI needs to make that an option. BSXCart becomes BSXCartridge. BSXFlash remains unchanged. I probably need to make Coprocessor::disable() functions now to free up memory on unload, but it shouldn't hurt anything the way it is. libsnes is most definitely broken to all hell and back now, and the debugger is still shot. I suppose we'll need some tricky code to work with the old ID system, and we'll need to add some more IDs for the new memory types.

And indeed it mostly is. But I like the idea of allowing some fun special effects and configurability that isn't system-wide. Note: there seems to be some kind of added audio lag in the SGB emulation now, and I don't really understand why. The code should be effectively identical to what I had before. The only main thing is that I'm sampling things to 48000hz instead of 32040hz before mixing. There's no point where I'm intentionally introducing added latency though. I'm kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be much appreciated :/ I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as well, and that would be very bad.

Update to v100r14 release. byuu says: (Windows: compile with -fpermissive to silence an annoying error. I'll fix it in the next WIP.) I completely replaced the time management system in higan and overhauled the scheduler. Before, processor threads would have "int64 clock"; and there would be a 1:1 relationship between two threads. When thread A ran for X cycles, it'd subtract X * B.Frequency from clock; and when thread B ran for Y cycles, it'd add Y * A.Frequency from clock. This worked well and allowed perfect precision; but it doesn't work when you have more complicated relationships: eg the 68K can sync to the Z80 and PSG; the Z80 to the 68K and PSG; so the PSG needs two counters. The new system instead uses a "uint64 clock" variable that represents time in attoseconds. Every time the scheduler exits, it subtracts the smallest clock count from all threads, to prevent an overflow scenario. The only real downside is that rounding errors mean that roughly every 20 minutes, we have a rounding error of one clock cycle (one 20,000,000th of a second.) However, this only applies to systems with multiple oscillators, like the SNES. And when you're in that situation ... there's no such thing as a perfect oscillator anyway. A real SNES will be thousands of times less out of spec than 1hz per 20 minutes. The advantages are pretty immense. First, we obviously can now support more complex relationships between threads. Second, we can build a much more abstracted scheduler. All of libco is now abstracted away completely, which may permit a state-machine / coroutine version of Thread in the future. We've basically gone from this: auto SMP::step(uint clocks) -> void { clock += clocks * (uint64)cpu.frequency; dsp.clock -= clocks; if(dsp.clock < 0 && !scheduler.synchronizing()) co_switch(dsp.thread); if(clock >= 0 && !scheduler.synchronizing()) co_switch(cpu.thread); } To this: auto SMP::step(uint clocks) -> void { Thread::step(clocks); synchronize(dsp); synchronize(cpu); } As you can see, we don't have to do multiple clock adjustments anymore. This is a huge win for the SNES CPU that had to update the SMP, DSP, all peripherals and all coprocessors. Likewise, we don't have to synchronize all coprocessors when one runs, now we can just synchronize the active one to the CPU. Third, when changing the frequencies of threads (think SGB speed setting modes, GBC double-speed mode, etc), it no longer causes the "int64 clock" value to be erroneous. Fourth, this results in a fairly decent speedup, mostly across the board. Aside from the GBA being mostly a wash (for unknown reasons), it's about an 8% - 12% speedup in every other emulation core. Now, all of this said ... this was an unbelievably massive change, so ... you know what that means >_> If anyone can help test all types of SNES coprocessors, and some other system games, it'd be appreciated. ---- Lastly, we have a bitchin' new about screen. It unfortunately adds ~200KiB onto the binary size, because the PNG->C++ header file transformation doesn't compress very well, and I want to keep the original resource files in with the higan archive. I might try some things to work around this file size increase in the future, but for now ... yeah, slightly larger archive sizes, sorry. The logo's a bit busted on Windows (the Label control's background transparency and alignment settings aren't working), but works well on GTK. I'll have to fix Windows before the next official release. For now, look on my Twitter feed if you want to see what it's supposed to look like. ---- EDIT: forgot about ICD2::Enter. It's doing some weird inverse run-to-save thing that I need to implement support for somehow. So, save states on the SGB core probably won't work with this WIP.

Update to v100r14 release. byuu says: (Windows: compile with -fpermissive to silence an annoying error. I'll fix it in the next WIP.) I completely replaced the time management system in higan and overhauled the scheduler. Before, processor threads would have "int64 clock"; and there would be a 1:1 relationship between two threads. When thread A ran for X cycles, it'd subtract X * B.Frequency from clock; and when thread B ran for Y cycles, it'd add Y * A.Frequency from clock. This worked well and allowed perfect precision; but it doesn't work when you have more complicated relationships: eg the 68K can sync to the Z80 and PSG; the Z80 to the 68K and PSG; so the PSG needs two counters. The new system instead uses a "uint64 clock" variable that represents time in attoseconds. Every time the scheduler exits, it subtracts the smallest clock count from all threads, to prevent an overflow scenario. The only real downside is that rounding errors mean that roughly every 20 minutes, we have a rounding error of one clock cycle (one 20,000,000th of a second.) However, this only applies to systems with multiple oscillators, like the SNES. And when you're in that situation ... there's no such thing as a perfect oscillator anyway. A real SNES will be thousands of times less out of spec than 1hz per 20 minutes. The advantages are pretty immense. First, we obviously can now support more complex relationships between threads. Second, we can build a much more abstracted scheduler. All of libco is now abstracted away completely, which may permit a state-machine / coroutine version of Thread in the future. We've basically gone from this: auto SMP::step(uint clocks) -> void { clock += clocks * (uint64)cpu.frequency; dsp.clock -= clocks; if(dsp.clock < 0 && !scheduler.synchronizing()) co_switch(dsp.thread); if(clock >= 0 && !scheduler.synchronizing()) co_switch(cpu.thread); } To this: auto SMP::step(uint clocks) -> void { Thread::step(clocks); synchronize(dsp); synchronize(cpu); } As you can see, we don't have to do multiple clock adjustments anymore. This is a huge win for the SNES CPU that had to update the SMP, DSP, all peripherals and all coprocessors. Likewise, we don't have to synchronize all coprocessors when one runs, now we can just synchronize the active one to the CPU. Third, when changing the frequencies of threads (think SGB speed setting modes, GBC double-speed mode, etc), it no longer causes the "int64 clock" value to be erroneous. Fourth, this results in a fairly decent speedup, mostly across the board. Aside from the GBA being mostly a wash (for unknown reasons), it's about an 8% - 12% speedup in every other emulation core. Now, all of this said ... this was an unbelievably massive change, so ... you know what that means >_> If anyone can help test all types of SNES coprocessors, and some other system games, it'd be appreciated. ---- Lastly, we have a bitchin' new about screen. It unfortunately adds ~200KiB onto the binary size, because the PNG->C++ header file transformation doesn't compress very well, and I want to keep the original resource files in with the higan archive. I might try some things to work around this file size increase in the future, but for now ... yeah, slightly larger archive sizes, sorry. The logo's a bit busted on Windows (the Label control's background transparency and alignment settings aren't working), but works well on GTK. I'll have to fix Windows before the next official release. For now, look on my Twitter feed if you want to see what it's supposed to look like. ---- EDIT: forgot about ICD2::Enter. It's doing some weird inverse run-to-save thing that I need to implement support for somehow. So, save states on the SGB core probably won't work with this WIP.

Update to v098r03 release. byuu says: It took several hours, but I've rebuilt much of the SNES' bus memory mapping architecture. The new design unifies the cartridge string-based mapping ("00-3f,80-bf:8000-ffff") and internal bus.map calls. The map() function now has an accompanying unmap() function, and instead of a fixed 256 callbacks, it'll scan to find the first available slot. unmap() will free slots up when zero addresses reference a given slot. The controllers and expansion port are now both entirely dynamic. Instead of load/unload/power/reset, they only have the constructor (power/reset/load) and destructor (unload). What this means is you can now dynamically change even expansion port devices after the system is loaded. Note that this is incredibly dangerous and stupid, but ... oh well. The whole point of this was for 21fx. There's no way to change the expansion port device prior to loading a game, but if the 21fx isn't active, then the reset vector hijack won't work. Now you can load a 21fx game, change the expansion port device, and simply reset the system to active the device. The unification of design between controller port devices and expansion port devices is nice, and overall this results in a reduction of code (all of the Mapping stuff in Cartridge is gone, replaced with direct bus mapping.) And there's always the potential to expand this system more in the future now. The big missing feature right now is the ability to push/pop mappings. So if you look at how the 21fx does the reset vector, you might vomit a little bit. But ... it works. Also changed exit(0) to _exit(0) in the POSIX version of nall::execute. [The _exit(0) thing is an attempt to make higan not crash when it tries to launch icarus and it's not on $PATH. The theory is that higan forks, then the child tries to exec icarus and fails, so it exits, all the unique_ptrs clean up their resources and tell the X server to free things the parent process is still using. Calling _exit() prevents destructors from running, and seems to prevent the problem. -Ed.]
