Update to v088r07 release. byuu says: (r05 and r06 were save points between large core modifications) I would really appreciate extensive regression testing (especially around SuperFX, Cx4, ST018, DSP-n, ST-01n, NES, GB) at this point. The most critical core changes should be completed now. And it was an unbelievable amount of restructuring. Changelog: - SuperFX core moved to Processor::GSU - SNES::CPU core moved to Processor::R65816 - SNES::SMP core moved to Processor::SPC700 - NES::CPU core renamed to Processor::R6502 - use filestream to load RAM files from interface - save states store SHA256 instead of CRC32 (CRC32 usage removed entirely from bsnes) - nes/ -> fc/ and NES -> FC - snes/ -> sfc/ and SNES -> SFC - SuperFamicom::MappedRAM::copy uses stream instead of data+size - Linux port uses gcc-4.7 (still using only gcc-4.6 subset, so you can make a gcc-4.6 symlink for now if you like.) - all profiles and all targets compile and work properly All eight instruction set cores have been moved to processor/ now. Consistency's a wonderful thing. The last remnants of NES/SNES are now limited to target-ui code; and the nall/(system) folder names. I'm building with gcc-4.7 on my Linux box now because the resultant binaries are up to 20% faster (seriously) than gcc-4.6.

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 v097r02 release. byuu says: Note: balanced/performance profiles still broken, sorry. Changelog: - added nall/GNUmakefile unique() function; used on linking phase of higan - added nall/unique_pointer - target-tomoko and {System}::Video updated to use unique_pointer<ClassName> instead of ClassName* [1] - locate() updated to search multiple paths [2] - GB: pass gekkio's if_ie_registers and boot_hwio-G test ROMs - FC, GB, GBA: merge video/ into the PPU cores - ruby: fixed ~AudioXAudio2() typo [1] I expected this to cause new crashes on exit due to changing the order of destruction of objects (and deleting things that weren't deleted before), but ... so far, so good. I guess we'll see what crops up, especially on OS X (which is already crashing for unknown reasons on exit.) [2] right now, the search paths are: programpath(), {configpath(), "higan/"}, {localpath(), "higan/"}; but we can add as many more as we want, and we can also add platform-specific versions.

Update to v097r13 release. byuu says: I refactored my schedulers. Added about ten lines to each scheduler, and removed about 100 lines of calling into internal state in the scheduler for the FC,SFC cores and about 30-40 lines for the other cores. All of its state is now private. Also reworked all of the entry points to static auto Enter() and auto main(). Where Enter() handles all the synchronization stuff, and main() doesn't need the while(true); loop forcing another layer of indentation everywhere. Took a few hours to do, but totally worth it. I'm surprised I didn't do this sooner. Also updated icarus gmake install rule to copy over the database.

Game Boy: uses DMG BIOS (the one with the slow title scroll) or SGB BIOS, based upon how you load the game. Game Boy Color: Everything except the IR port is emulated. I don't have any plans to allow linking two instances of bsnes. And that's frankly never going to happen over netplay anyway, due to latency requirements of the serial/IR ports. The new DMA stuff is possibly incorrect, my test games don't seem to use it. Zelda: DX usually resets or crashes on the intro right before the beach scene. I'm not sure why. Skip the intro and the game plays fine. This is the best I can do when the most up-to-date GB/C reference document is over ten years old and half-assed (pandocs.) I could really use some help from anyone who understands the system. Probably the worst part of my emulation at the moment is the interrupt system. Lots of things real hardware doesn't allow (DMA outside HRAM, CGB DMA to invalid addresses, etc) isn't blocked yet. LCD renderer is still scanline-based, which is just terrible. Doesn't seem to be any good docs on cycle-level operation. I only know that it's incredibly pathological and variable.

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 v097r13 release. byuu says: I refactored my schedulers. Added about ten lines to each scheduler, and removed about 100 lines of calling into internal state in the scheduler for the FC,SFC cores and about 30-40 lines for the other cores. All of its state is now private. Also reworked all of the entry points to static auto Enter() and auto main(). Where Enter() handles all the synchronization stuff, and main() doesn't need the while(true); loop forcing another layer of indentation everywhere. Took a few hours to do, but totally worth it. I'm surprised I didn't do this sooner. Also updated icarus gmake install rule to copy over the database.

Update to v098r06 release. byuu says: Changelog: - emulation cores now refresh video from host thread instead of cothreads (fix AMD crash) - SFC: fixed another bug with leap year months in SharpRTC emulation - SFC: cleaned up camelCase on function names for armdsp,epsonrtc,hitachidsp,mcc,nss,sharprtc classes - GB: added MBC1M emulation (requires manually setting mapper=MBC1M in manifest.bml for now, sorry) - audio: implemented Emulator::Audio mixer and effects processor - audio: implemented Emulator::Stream interface - it is now possible to have more than two audio streams: eg SNES + SGB + MSU1 + Voicer-Kun (eventually) - audio: added reverb delay + reverb level settings; exposed balance configuration in UI - video: reworked palette generation to re-enable saturation, gamma, luminance adjustments - higan/emulator.cpp is gone since there was nothing left in it I know you guys are going to say the color adjust/balance/reverb stuff is pointless. 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.

All of higan was updated to use the new foo& bar syntax, and I also updated switch statements to be consistent as well (but not in the disassemblers, was starting to get an RSI just from what I already did.) phoenix/{windows, cocoa, qt} need to be updated to use "string foo" instead of "const string& foo", and after that, the major diffs should be finished. This archive is the first time I'm posting my copy-on-write, size+capacity nall::string class, so any feedback on that is welcome as well.

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 :/

Fixed libsnes to compile: Themaister, can you please test to make sure it works? I don't have a libsnes client on my work PC to test it. Added about / license information to bottom of advanced settings screen for now (better than nothing, I guess.) Blocked PPU reads/writes while rendering for now, easier than coming up with a bus address locking thing :/ I can't seem to fix MMC5 graphics during the intro to Uchuu Keibitai. Without that, trying to implement vertical-split screen mode doesn't make sense. So as far as special audio chips go ... * VRC6 is completed * Sunsoft 5B has everything the only game to use it uses, but there are more unused channels I'd like to support anyway (they aren't documented, though.) * MMC5 audio unsupported for now * VRC7 audio unsupported, probably for a long time (hardest audio driver of all. More complex than core NES APU.) * audio PCM games (Moero Pro Yakyuu!) I probably won't ever support (they require external WAV packs.)

Update to v083r03 release. byuu says: Lots of phoenix issues fixed, especially for Windows and GTK+. NES emulation passes all ten ppu_vbl_nmi tests from blargg. Sprite timing is nowhere near accurate yet (always consumes four clocks per sprite), but oh well.

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.

Update to v082r33 release. byuu says: Added MMC2, MMC4, VRC4, VRC7 (no audio.) Split NES audio code up into individual modules. Fixed libsnes to compile: Themaister, can you please test to make sure it works? I don't have a libsnes client on my work PC to test it. Added about / license information to bottom of advanced settings screen for now (better than nothing, I guess.) Blocked PPU reads/writes while rendering for now, easier than coming up with a bus address locking thing :/ I can't seem to fix MMC5 graphics during the intro to Uchuu Keibitai. Without that, trying to implement vertical-split screen mode doesn't make sense. So as far as special audio chips go ... * VRC6 is completed * Sunsoft 5B has everything the only game to use it uses, but there are more unused channels I'd like to support anyway (they aren't documented, though.) * MMC5 audio unsupported for now * VRC7 audio unsupported, probably for a long time (hardest audio driver of all. More complex than core NES APU.) * audio PCM games (Moero Pro Yakyuu!) I probably won't ever support (they require external WAV packs.)

I need to consider how crazy it'd be to emulate the logic IC and have boards simply reroute pins to it. If it's too much work, we'll just treat mappers as board + logic IC combinations. We'll see.

I reduced the complexity of all eight supported mapping modes, and standardized them; and added in an overscan filter (not in archive) for chopping off all the NES edge garbage (8 pixels on the left and right, 16 on the top and bottom.) It's extreme, but anything less shows junk. I may make this part of the menu option, just clip off more on NES mode than SNES mode.

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 v082r08 release. byuu says: Fixed up the PPU to be as close to cycle-perfect as possible. Fixed RMW to write twice instead of read twice. Ryphecha added AOROM and fixed up MMC1. Have CNROM too, but I need to rethink the mapper/board distinction. Apparently the same logic IC is used in both AOROM and CNROM, and it's just a matter of routing the pins to it. I need to consider how crazy it'd be to emulate the logic IC and have boards simply reroute pins to it. If it's too much work, we'll just treat mappers as board + logic IC combinations. We'll see.

All of higan was updated to use the new foo& bar syntax, and I also updated switch statements to be consistent as well (but not in the disassemblers, was starting to get an RSI just from what I already did.) phoenix/{windows, cocoa, qt} need to be updated to use "string foo" instead of "const string& foo", and after that, the major diffs should be finished.

I reduced the complexity of all eight supported mapping modes, and standardized them; and added in an overscan filter (not in archive) for chopping off all the NES edge garbage (8 pixels on the left and right, 16 on the top and bottom.) It's extreme, but anything less shows junk. I may make this part of the menu option, just clip off more on NES mode than SNES mode.

I don't have any plans to allow linking two instances of bsnes. And that's frankly never going to happen over netplay anyway, due to latency requirements of the serial/IR ports. The new DMA stuff is possibly incorrect, my test games don't seem to use it. Zelda: DX usually resets or crashes on the intro right before the beach scene. I'm not sure why. Skip the intro and the game plays fine. This is the best I can do when the most up-to-date GB/C reference document is over ten years old and half-assed (pandocs.) I could really use some help from anyone who understands the system. Probably the worst part of my emulation at the moment is the interrupt system. Lots of things real hardware doesn't allow (DMA outside HRAM, CGB DMA to invalid addresses, etc) isn't blocked yet. LCD renderer is still scanline-based, which is just terrible. Doesn't seem to be any good docs on cycle-level operation. I only know that it's incredibly pathological and variable.

Update to v082r25 release. byuu says: Ryphecha fixed Gun Nac, it was some sort of problem with blank sprite address fetching messing with the MMC3 I've started on an XML parser for iNES-free loading, but it's pretty barebones right now. Only NROM-256 loads, and you have to make it a compile-time thing (so other games work for now.) Updated nall with nullptr stuff. nall/detect is now nall/intrinsic and has both #defines + static constants that can be used to detect the platform (allows for run-time platform checks where practical.) ruby has a Makefile now, that makes using it in other projects a lot easier

Update to v095r09 release. byuu says: Changelog: - all of fc/ ported to "auto function() -> return;" syntax - (includes all of cartridge/board and cartridge/chip as well; even though they're all deprecated) - sfc balanced profile ported to "auto function() -> return;" syntax - sfc balanced and performance profiles compile again - Linux always gets -ldl - removed arch=x86 logic from nall/GNUmakefile, as TDM/GCC64 can't produce bug-free 32-bit binaries anyway The only code that continues to use the old function syntax is the SFC performance core, obscure parts of nall that higan doesn't use, and the pieces of code that weren't written by me (blargg's SFC-DSP, Ryphecha's sinc resampler, and OV2's xaudio2 header file.) I was too burned out to finish it tonight. The above was about four hours straight of non-stop typing. Really can't wait to be done with this once and for all.

Update to v082r08 release. byuu says: Fixed up the PPU to be as close to cycle-perfect as possible. Fixed RMW to write twice instead of read twice. Ryphecha added AOROM and fixed up MMC1. Have CNROM too, but I need to rethink the mapper/board distinction. Apparently the same logic IC is used in both AOROM and CNROM, and it's just a matter of routing the pins to it. I need to consider how crazy it'd be to emulate the logic IC and have boards simply reroute pins to it. If it's too much work, we'll just treat mappers as board + logic IC combinations. We'll see.

Update to v082r31 release. byuu says: Enable Overscan->Mask Overscan [best I'm doing] Video settings -> Overscan mask: (horizontal, vertical: 0-16 on each side) [only works on NES+SNES] BPS patching works for NES+SNES+GB; note that long-term I want BPS to only patch headerless PRG+CHR files, but we'll need a database / completed board mapping system first. MMC1 splits the board/chip markups a bit better. My attempts to emulate the extra CHR bits per hardware fail repeatedly. Docs do not explain how it works at all. Emulated enough of the MMC5 to play Castlevania 3. The MMC5 is easily the most complicated mapper the NES has to offer, and of course, has the most pitifully vague and difficult documentation of any mapper around. It seems the only way anyone is able to emulate this chip is empirically. Everyone else apparently hooks the MMC5 right into the PPU core, which I of course cannot do. So I had to come up with my own (probably wrong) way to synchronize the PPU simply by observing CHR bus accesses. I must say, I over-estimated how well fleshed out the NES hardware documentation was. Shit hits the fan right after MMC3. It's miles beyond the GB scene, but I find myself wanting for someone with the technical writing ability of anomie. I can't find anything at all on how we're supposed to support the $2007 port reads/writes without it extra-clocking the PPU's bus, which could throw off mapper timing. Absolutely nothing at all on the subject anywhere, something everybody is required to do for all cycle-based emulators and ... nada. Anyway, I'd like to refine the MMC5 a bit, getting Just Breed playable even without sound would be really nice (it's a fun game.) Then we need to get libsnes building again (ugh, getting worn out in backporting changes to it.) Once v083 is public, we can start discussing a new API for multiple emulators.

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 :/
