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 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

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 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.]

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 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.]
