Update to v103r01 release. byuu says: Changelog: - nall/dsp: improve one pole coefficient calculations [Fatbag] - higan/audio: reworked filters to support selection of either one pole (first-order) or biquad (second-order) filters - note: the design is not stable yet; so forks should not put too much effort into synchronizing with this change yet - fc: added first-order filters as per NESdev wiki (90hz lowpass + 440hz lowpass + 14khz highpass) - fc: created separate NTSC-J and NTSC-U regions - NESdev wiki says the Japanese Famicom uses a separate audio filtering strategy, but details are fuzzy - there's also cartridge audio output being disabled on NES units; and differences with controllers - this stuff will be supported in the future, just adding the support for it now - gba: corrected serious bugs in PSG wave channel emulation [Cydrak] - note that if there are still bugs here, it's my fault - md/psg,ym2612: added first-order low-pass 2840hz filter to match VA3-VA6 Mega Drives - md/psg: lowered volume relative to the YM2612 - using 0x1400; multiple people agreed it was the closest to the hardware recordings against a VA6 - ms,md/psg: don't serialize the volume levels array - md/vdp: Hblank bit acts the same during Vblank as outside of it (it isn't always set during Vblank) - md/vdp: return isPAL in bit 0 of control port reads - tomoko: change command-line option separator from : to | - [Editor's note: This change was present in the public v103, but it's in this changelog because it was made after the v103 WIP] - higan/all: change the 20hz high-pass filters from second-order three-pass to first-order one-pass - these filters are meant to remove DC bias, but I honestly can't hear a difference with or without them - so there's really no sense wasting CPU power with an extremely powerful filter here Things I did not do: - change icarus install rule - work on 8-bit Mega Drive SRAM - work on Famicom or Mega Drive region detection heuristics in icarus My long-term dream plan is to devise a special user-configurable filtering system where you can set relative volumes and create your own list of filters (any number of them in any order at any frequency), that way people can make the systems sound however they want. Right now, the sanest place to put this information is inside the $system.sys/manifest.bml files. But that's not very user friendly, and upgrading to new versions will lose these changes if you don't copy them over manually. Of course, cluttering the GUI with a fancy filter editor is probably supreme overkill for 99% of users, so maybe that's fine.

Update to v103 WIP release. byuu says (in the WIP forum): Changelog: - higan: cheat codes accept = and ? separators now - the new preferred code format is: address=value or address=if-match?value - the old code format of address/value and address/if-match/value will continue to work - higan: cheats.bml is no longer included with the base distribution - mightymo stopped updating it in 2015, and it's not source code; it can still be pulled in from older releases - fc: improved PAL mode timing; use PAL APU timing tables; fix PAL noise period table [hex\_usr] - md: support aborting a Z80 bus wait in order to capture save states without freezing - note that this will violate accuracy; but in practice a slight desync is better than an emulator deadlock - sfc: revert DSP ENDX randomization for now (want to research it more before deploying in an official release) - sfc: fix Super Famicom.sys/manifest.bml APU RAM size [hex\_usr] - tomoko: cleaned up make install rules - hiro/cocoa: use ABGR for pixel data [Sintendo] Note: I forgot to change the command-line and drag-and-drop separator from : to | in this WIP. However, it is corrected in the v103 official binary and source published on download.byuu.org. Sorry about that, I know it makes the Git repository history more difficult. I'm not concerned whether the : → | change is part of v103 or v103r01 in the repository, and will leave this to your discretion, Screwtape. I also still need to set the VDP bit to indicate PAL mode in the Mega Drive core. This is what happens when I have 47 things I have to do, given how lousy my memory is. I miss things.

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

auto pathID() const -> uint { return information.pathID; }
Update to v102r28 release. byuu says: Changelog: - higan: `Emulator::<Platform::load>()` now returns a struct containing both a path ID and a string option - higan: `Emulator::<Platform::load>()` now takes an optional final argument of string options - fc: added PAL emulation (finally, only took six years) - md: added PAL emulation - md: fixed address parameter to `VDP::Sprite::write()`; fixes missing sprites in Super Street Fighter II - md: emulated HIRQ counter; fixes many games - Super Street Fighter II - status bar - Altered Beast - status bar - Sonic the Hedgehog - Labyrinth Zone - water effect - etc. - ms: added PAL emulation - sfc: added the ability to override the default region auto-detection - sfc: removed "system.region" override setting from `Super Famicom.sys` - tomoko: added options list to game folder load dialog window - tomoko: added the ability to specify game folder load options on the command-line So, basically ... Sega forced a change with the way region detection works. You end up with games that can run on multiple regions, and the content changes accordingly. Bare Knuckle in NTSC-J mode will become Streets of Rage in NTSC-U mode. Some games can even run in both NTSC and PAL mode. In my view, there should be a separate ROM for each region a game was released in, even if the ROM content were identical. But unfortunately that's not how things were done by anyone else. So to support this, the higan load dialog now has a drop-down at the bottom-right, where you can choose the region to load games from. On the SNES, it defaults to "Auto", which will pull the region setting from the manifest, or fall back on NTSC. On the Mega Drive ... unfortunately, I can't auto-detect the region from the ROM header. $1f0 is supposed to contain a string like "JUE", but instead you get games like Maui Mallard that put an "A" there, and other such nonsense. Sega was far more lax than Nintendo with the ROM header validity. So for now at least, you have to manually select your region every time you play a Mega Drive game, thus you have "NTSC-J", "NTSC-U", and "PAL". The same goes for the Master System for the same reason, but there's only "NTSC" and "PAL" here. I'm not sure if games have a way to detect domestic vs international consoles. And for now ... the Famicom is the same as well, with no auto-detection. I'd sincerely hope iNES has a header bit for the region, but I didn't bother with updating icarus to support that yet. The way to pass these parameters on the command-line is to prefix the game path with "option:", so for example:    higan "PAL:/path/to/Sonic the Hedgehog (USA, Europe).md" If you don't provide a prefix, it uses the default (NTSC-J, NTSC, or Auto.) Obviously, it's not possible to pass parameters with drag-and-drop, so you will always get the default option in said case.

Update to v099r07 release. byuu says: Changelog: - (hopefully) fixed BS Memory and Sufami Turbo slot loading - ported GB, GBA, WS cores to use nall/vfs - completely removed loadRequest, saveRequest functionality from Emulator::Interface and ui-tomoko - loadRequest(folder) is now load(folder) - save states now use a shared Emulator::SerializerVersion string - whenever this is bumped, all older states will break; but this makes bumping state versions way easier - also, the version string makes it a lot easier to identify compatibility windows for save states - SNES PPU now uses uint16 vram[32768] for memory accesses [hex_usr] NOTE: Super Game Boy loading is currently broken, and I'm not entirely sure how to fix it :/ The file loading handoff was -really- complicated, and so I'm kind of at a loss ... so for now, don't try it. Everything else should theoretically work, so please report any bugs you find. So, this is pretty much it. I'd be very curious to hear feedback from people who objected to the old nall/stream design, whether they are happy with the new file loading system or think it could use further improvements. The 16-bit VRAM turned out to be a wash on performance (roughly the same as before. 1fps slower on Zelda 3, 1fps faster on Yoshi's Island.) The main reason for this was because Yoshi's Island was breaking horribly until I changed the vramRead, vramWrite functions to take uint15 instead of uint16. I suspect the issue is we're using uint16s in some areas now that need to be uint15, and this game is setting the VRAM address to 0x8000+, causing us to go out of bounds on memory accesses. But ... I want to go ahead and do something cute for fun, and just because we can ... and this new interface is so incredibly perfect for it!! I want to support an SNES unit with 128KiB of VRAM. Not out of the box, but as a fun little tweakable thing. The SNES was clearly designed to support that, they just didn't use big enough VRAM chips, and left one of the lines disconnected. So ... let's connect it anyway! In the end, if we design it right, the only code difference should be one area where we mask by 15-bits instead of by 16-bits.

Update to v082r04 release. byuu says: So, here's the deal. I now have three emulators. I don't think the NES/GB ones are at all useful, but I do want them to be eventually. And having them have those pathetic little GUIs like ui-gameboy, and keeping everything in separate project folders, just doesn't work well for me. I kind of "got around" the issue with the Game Boy, by only allowing SGB mode emulation. But there is no "Super Nintendo" ... er ... wait ... uhmm ... well, you know what I mean anyway. So, my idea is to write a multi-emulator GUI, and keep the projects together. The GUI is not going to change much. The way I envision this working: At startup, you have a menubar with: "Cartridge, Settings, Tools, Help". Cartridge has "Load NES Cartridge", "Load SNES Cartridge", etc. When you load something, Cartridge is replaced with the appropriate system menu, eg "SNES". Here you have all your regular items: "power, reset, controller port selection, etc." There is also a new "Unload Cartridge" option, which is how you restore the "Cartridge" menu again. I have no plans to emulate any other systems, but if I ever do emulate something that doesn't take cartridges, I'll change the name to just "Load" or something. The cheat editor / state manager will look and act exactly the same. The settings panel will look exactly the same. I'll simply show/hide system-specific options as needed, like NES/SNES aspect ratio correction, etc. The input mapping window will just have settings for the currently loaded system. Video and audio tweaking will apply cross-system, as will hotkey mapping. The GUI stuff is mostly copy-paste, so it should only take me a week to get it 95% back to where it was, so don't worry, this isn't total GUI rewrite #80. I am, however, making all the objects pointers, so that I can destruct them all prior to main() returning, which is certainly one way of fixing that annoying Windows/Qt crash. Please only test on Linux. The Windows port is broken to hell, and will give you a bad impression of the idea: - menu groups are not hiding for some reason (all groups are showing, it looks hideous) - Timer interval(0) is taking 16ms per call, capping the FPS to ~64 tops [FWIW, bsnes/accuracy gets 130fps, bgameboy gets 450fps, bnes gets 800fps; all run at lowest possible granularity] - the OS keeps beeping when you press keys (AGAIN) Of course, Qt and GTK+ don't let you shrink a window from the requested geometry size, because they suck. So the video scaling stuff doesn't work all that great yet. Man, a metric fuckton of things need to be fixed in phoenix, and I really don't know how to fix any of them :/

Update to v087r30 release. byuu says: Changelog: - DMA channel masks added (some are 27-bit source/target and some are 14-bit length -- hooray, varuint_t class.) - No more state.pending flags. Instead, we set dma.pending flag when we want a transfer (fixes GBA Video - Pokemon audio) [Cydrak] - fixed OBJ Vmosaic [Cydrak, krom] - OBJ cannot read <=0x13fff in BG modes 3-5 (fixes the garbled tile at the top-left of some games) - DMA timing should be much closer to hardware now, but probably not perfect - PPU frame blending uses blargg's bit-perfect, rounded method (slower, but what can you do?) - GBA carts really unload now - added nall/gba/cartridge.hpp: used when there is no manifest. Scans ROMs for library tags, and selects the first valid one found - added EEPROM auto-detection when EEPROM size=0. Forces disk/save state size to 8192 (otherwise states could crash between pre and post detect.) - detects first read after a set read address command when the size is zero, and sets all subsequent bit-lengths to that value, prints detected size to terminal - added nall/nes/cartridge.hpp: moves iNES detection out of emulation core. Important to note: long-term goal is to remove all nall/(system)/cartridge.hpp detections from the core and replace with databases. All in good time. Anyway, the GBA workarounds should work for ~98.5% of the library, if my pre-scanning was correct (~40 games with odd tags. I reject ones without numeric versions now, too.) I think we're basically at a point where we can release a new version now. Compatibility should be relatively high (at least for a first release), and fixes are only going to affect one or two games at a time. I'd like to start doing some major cleaning house internally (rename NES->Famicom, SNES->SuperFamicom and such.) Would be much wiser to do that on a .01 WIP to minimize regressions. The main problems with a release now: - speed is pretty bad, haven't really optimized much yet (not sure how much we can improve it yet, this usually isn't easy) - sound isn't -great-, but the GBA audio sucks anyway :P - couple of known bugs (Sonic X video, etc.)

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 v102r28 release. byuu says: Changelog: - higan: `Emulator::<Platform::load>()` now returns a struct containing both a path ID and a string option - higan: `Emulator::<Platform::load>()` now takes an optional final argument of string options - fc: added PAL emulation (finally, only took six years) - md: added PAL emulation - md: fixed address parameter to `VDP::Sprite::write()`; fixes missing sprites in Super Street Fighter II - md: emulated HIRQ counter; fixes many games - Super Street Fighter II - status bar - Altered Beast - status bar - Sonic the Hedgehog - Labyrinth Zone - water effect - etc. - ms: added PAL emulation - sfc: added the ability to override the default region auto-detection - sfc: removed "system.region" override setting from `Super Famicom.sys` - tomoko: added options list to game folder load dialog window - tomoko: added the ability to specify game folder load options on the command-line So, basically ... Sega forced a change with the way region detection works. You end up with games that can run on multiple regions, and the content changes accordingly. Bare Knuckle in NTSC-J mode will become Streets of Rage in NTSC-U mode. Some games can even run in both NTSC and PAL mode. In my view, there should be a separate ROM for each region a game was released in, even if the ROM content were identical. But unfortunately that's not how things were done by anyone else. So to support this, the higan load dialog now has a drop-down at the bottom-right, where you can choose the region to load games from. On the SNES, it defaults to "Auto", which will pull the region setting from the manifest, or fall back on NTSC. On the Mega Drive ... unfortunately, I can't auto-detect the region from the ROM header. $1f0 is supposed to contain a string like "JUE", but instead you get games like Maui Mallard that put an "A" there, and other such nonsense. Sega was far more lax than Nintendo with the ROM header validity. So for now at least, you have to manually select your region every time you play a Mega Drive game, thus you have "NTSC-J", "NTSC-U", and "PAL". The same goes for the Master System for the same reason, but there's only "NTSC" and "PAL" here. I'm not sure if games have a way to detect domestic vs international consoles. And for now ... the Famicom is the same as well, with no auto-detection. I'd sincerely hope iNES has a header bit for the region, but I didn't bother with updating icarus to support that yet. The way to pass these parameters on the command-line is to prefix the game path with "option:", so for example:    higan "PAL:/path/to/Sonic the Hedgehog (USA, Europe).md" If you don't provide a prefix, it uses the default (NTSC-J, NTSC, or Auto.) Obviously, it's not possible to pass parameters with drag-and-drop, so you will always get the default option in said case.

Update to v099r07 release. byuu says: Changelog: - (hopefully) fixed BS Memory and Sufami Turbo slot loading - ported GB, GBA, WS cores to use nall/vfs - completely removed loadRequest, saveRequest functionality from Emulator::Interface and ui-tomoko - loadRequest(folder) is now load(folder) - save states now use a shared Emulator::SerializerVersion string - whenever this is bumped, all older states will break; but this makes bumping state versions way easier - also, the version string makes it a lot easier to identify compatibility windows for save states - SNES PPU now uses uint16 vram[32768] for memory accesses [hex_usr] NOTE: Super Game Boy loading is currently broken, and I'm not entirely sure how to fix it :/ The file loading handoff was -really- complicated, and so I'm kind of at a loss ... so for now, don't try it. Everything else should theoretically work, so please report any bugs you find. So, this is pretty much it. I'd be very curious to hear feedback from people who objected to the old nall/stream design, whether they are happy with the new file loading system or think it could use further improvements. The 16-bit VRAM turned out to be a wash on performance (roughly the same as before. 1fps slower on Zelda 3, 1fps faster on Yoshi's Island.) The main reason for this was because Yoshi's Island was breaking horribly until I changed the vramRead, vramWrite functions to take uint15 instead of uint16. I suspect the issue is we're using uint16s in some areas now that need to be uint15, and this game is setting the VRAM address to 0x8000+, causing us to go out of bounds on memory accesses. But ... I want to go ahead and do something cute for fun, and just because we can ... and this new interface is so incredibly perfect for it!! I want to support an SNES unit with 128KiB of VRAM. Not out of the box, but as a fun little tweakable thing. The SNES was clearly designed to support that, they just didn't use big enough VRAM chips, and left one of the lines disconnected. So ... let's connect it anyway! In the end, if we design it right, the only code difference should be one area where we mask by 15-bits instead of by 16-bits.

Update to higan v091r14 and ananke v00r03 releases. byuu says: higan changelog: - generates title displayed in emulator window by asking the core - core builds title solely from "information/title" ... if it's not there, you don't get a title at all - sub-system load menu is gone ... since there are multiple revisions of the SGB, this never really worked well anyway - to load an SGB, BS-X or ST cartridge, load the base cartridge first - "File->Load Game" moved to "Load->Import Game" ... may cause a bit of confusion to new users, but I don't like having a single-item menu, we'll just have to explain it to new users - browser window redone to look like ananke - home button here goes to ~/Emulation rather than just ~ like ananke, since this is the home of game folders - game folder icon is now the executable icon for the Tango theme (orange diamond), meant to represent a complete game rather than a game file or archive ananke changelog: - outputs GBC games to "Game Boy Color/" instead of "Game Boy/" - adds the file basename to "information/title" Known issues: - using ananke to load a GB game trips the Super Famicom SGB mode and fails (need to make the full-path auto-detection ignore non-bootable systems) - need to dump and test some BS-X media before releasing - ananke lacks BS-X Satellaview cartridge support - v092 isn't going to let you retarget the ananke/higan game folder path of ~/Emulation, you will have to wait for a future version if that bothers you so greatly [Later, after the v092 release, byuu posted this additional changelog: - kill laevateinn - add title() - add bootable, remove load - combine file, library - combine [][][] paths - fix SFC subtype handling XML->BML - update file browser to use buttons - update file browser keyboard handling - update system XML->BML - fix sufami turbo hashing - remove Cartridge::manifest ]

Update to v087r30 release. byuu says: Changelog: - DMA channel masks added (some are 27-bit source/target and some are 14-bit length -- hooray, varuint_t class.) - No more state.pending flags. Instead, we set dma.pending flag when we want a transfer (fixes GBA Video - Pokemon audio) [Cydrak] - fixed OBJ Vmosaic [Cydrak, krom] - OBJ cannot read <=0x13fff in BG modes 3-5 (fixes the garbled tile at the top-left of some games) - DMA timing should be much closer to hardware now, but probably not perfect - PPU frame blending uses blargg's bit-perfect, rounded method (slower, but what can you do?) - GBA carts really unload now - added nall/gba/cartridge.hpp: used when there is no manifest. Scans ROMs for library tags, and selects the first valid one found - added EEPROM auto-detection when EEPROM size=0. Forces disk/save state size to 8192 (otherwise states could crash between pre and post detect.) - detects first read after a set read address command when the size is zero, and sets all subsequent bit-lengths to that value, prints detected size to terminal - added nall/nes/cartridge.hpp: moves iNES detection out of emulation core. Important to note: long-term goal is to remove all nall/(system)/cartridge.hpp detections from the core and replace with databases. All in good time. Anyway, the GBA workarounds should work for ~98.5% of the library, if my pre-scanning was correct (~40 games with odd tags. I reject ones without numeric versions now, too.) I think we're basically at a point where we can release a new version now. Compatibility should be relatively high (at least for a first release), and fixes are only going to affect one or two games at a time. I'd like to start doing some major cleaning house internally (rename NES->Famicom, SNES->SuperFamicom and such.) Would be much wiser to do that on a .01 WIP to minimize regressions. The main problems with a release now: - speed is pretty bad, haven't really optimized much yet (not sure how much we can improve it yet, this usually isn't easy) - sound isn't -great-, but the GBA audio sucks anyway :P - couple of known bugs (Sonic X video, etc.)

The only use case left for Emulator::Interface::path(uint id) is for 21fx emulation. This peripheral loads a DLL/SO via LoadLibrary/dlopen, which do not have any official ways to open a file in RAM. I'm very hesitant to use the portable trick of writing the memory to a temporary file, loading it, and deleting the temporary file once done ... it's a real waste of disk activity. I might make something like vfs::file::isVirtual->bool,path()->string to get around this. But even once I do, the underlying LoadLibrary/dlopen call is still going to be direct disk access.

Update to v082r04 release. byuu says: So, here's the deal. I now have three emulators. I don't think the NES/GB ones are at all useful, but I do want them to be eventually. And having them have those pathetic little GUIs like ui-gameboy, and keeping everything in separate project folders, just doesn't work well for me. I kind of "got around" the issue with the Game Boy, by only allowing SGB mode emulation. But there is no "Super Nintendo" ... er ... wait ... uhmm ... well, you know what I mean anyway. So, my idea is to write a multi-emulator GUI, and keep the projects together. The GUI is not going to change much. The way I envision this working: At startup, you have a menubar with: "Cartridge, Settings, Tools, Help". Cartridge has "Load NES Cartridge", "Load SNES Cartridge", etc. When you load something, Cartridge is replaced with the appropriate system menu, eg "SNES". Here you have all your regular items: "power, reset, controller port selection, etc." There is also a new "Unload Cartridge" option, which is how you restore the "Cartridge" menu again. I have no plans to emulate any other systems, but if I ever do emulate something that doesn't take cartridges, I'll change the name to just "Load" or something. The cheat editor / state manager will look and act exactly the same. The settings panel will look exactly the same. I'll simply show/hide system-specific options as needed, like NES/SNES aspect ratio correction, etc. The input mapping window will just have settings for the currently loaded system. Video and audio tweaking will apply cross-system, as will hotkey mapping. The GUI stuff is mostly copy-paste, so it should only take me a week to get it 95% back to where it was, so don't worry, this isn't total GUI rewrite #80. I am, however, making all the objects pointers, so that I can destruct them all prior to main() returning, which is certainly one way of fixing that annoying Windows/Qt crash. Please only test on Linux. The Windows port is broken to hell, and will give you a bad impression of the idea: - menu groups are not hiding for some reason (all groups are showing, it looks hideous) - Timer interval(0) is taking 16ms per call, capping the FPS to ~64 tops [FWIW, bsnes/accuracy gets 130fps, bgameboy gets 450fps, bnes gets 800fps; all run at lowest possible granularity] - the OS keeps beeping when you press keys (AGAIN) Of course, Qt and GTK+ don't let you shrink a window from the requested geometry size, because they suck. So the video scaling stuff doesn't work all that great yet. Man, a metric fuckton of things need to be fixed in phoenix, and I really don't know how to fix any of them :/
