Raw Normal View History

Update to v099r13 release. byuu says: Changelog: - GB core code cleanup completed - GBA core code cleanup completed - some more cleanup on missed processor/arm functions/variables - fixed FC loading icarus bug - "Load ROM File" icarus functionality restored - minor code unification efforts all around (not perfect yet) - MMIO->IO - mmio.cpp->io.cpp - read,write->readIO,writeIO It's been a very long work in progress ... starting all the way back with v094r09, but the major part of the higan code cleanup is now completed! Of course, it's very important to note that this is only for the basic style: - under_score functions and variables are now camelCase - return-type function-name() are now auto function-name() -> return-type - Natural<T>/Integer<T> replace (u)intT_n types where possible - signed/unsigned are now int/uint - most of the x==true,x==false tests changed to x,!x A lot of spot improvements to consistency, simplicity and quality have gone in along the way, of course. But we'll probably never fully finishing beautifying every last line of code in the entire codebase. Still, this is a really great start. Going forward, WIP diffs should start being smaller and of higher quality once again. I know the joke is, "until my coding style changes again", but ... this was way too stressful, way too time consuming, and way too risky. I'm too old and tired now for extreme upheavel like this again. The only major change I'm slowly mulling over would be renaming the using Natural<T>/Integer<T> = (u)intT; shorthand to something that isn't as easily confused with the (u)int_t types ... but we'll see. I'll definitely continue to change small things all the time, but for the larger picture, I need to just accept the style I have and live with it.

Update to v097r17 release. byuu says: Changelog: - ruby: if DirectSoundCreate fails (no sound device present), return false from init instead of crashing - nall: improved edge case return values for (basename,pathname,dirname,...) - nall: renamed file_system_object class to inode - nall: varuint_t replaced with VariadicNatural; which contains .bit,.bits,.byte ala Natural/Integer - nall: fixed boolean compilation error on Windows - WS: popa should not restore SP - GBA: rewrote the CPU/APU cores to use the .bit,.bits functions; removed registers.cpp from each Note that the GBA changes are extremely major. This is about five hours worth of extremely delicate work. Any slight errors could break emulation in extremely bad ways. Let's hold off on extensive testing until the next WIP, after I do the same to the PPU. So far ... endrift's SOUNDCNT_X I/O test is failing, although that code didn't change, so clearly I messed up SOUNDCNT_H somehow ...

Update to v087r19 release. byuu says: Changelog: - added FIFO buffer emulation (with DMA and all that jazz) [Cydrak] - fixed timers and vcounter assign [Cydrak] - emulated EEPROM (you have to change size manually for 14-bit mode, we need a database badly now) [SMA runs now] - removed OAM array, now decoding directly to struct Object {} [128] and ObjectParam {} [32] (faster this way) - check forceblank (still doesn't remove all garble between transitions, though??) - lots of other stuff Delete your settings.cfg, or manually change frequencyGBA to 32768, or bad things will happen (this may change back to 256KHz-4MHz later.) 15 of 16 games are fully playable now, and look and sound great. The major missing detail right now is PPU blending support, and we really need to optimize the hell out of the code.

Update to v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot. My plan for BS-X slotted cartridges is to require a manifest.xml to specify that it has the BS-X slot present. Otherwise, we have to load the ROM into the SNES cartridge class, and parse its header before we can find out if it has one. Screw that. If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.

Update to v098r11 release. byuu says: Changelog: - fixed nall/path.hpp compilation issue - fixed ruby/audio/xaudio header declaration compilation issue (again) - cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the file was whitespace overkill) - added null terminator entry to nall/windows/utf8.hpp argc[] array - nall/windows/guid.hpp uses the Windows API for generating the GUID - this should stop all the bug reports where two nall users were generating GUIDs at the exact same second - fixed hiro/cocoa compilation issue with uint# types - fixed major higan/sfc Super Game Boy audio latency issue - fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions - major cleanups to higan/processor/r65816 core - merged emulation/native-mode opcodes - use camel-case naming on memory.hpp functions - simplify address masking code for memory.hpp functions - simplify a few opcodes themselves (avoid redundant copies, etc) - rename regs.* to r.* to match modern convention of other CPU cores - removed device.order<> concept from Emulator::Interface - cores will now do the translation to make the job of the UI easier - fixed plurality naming of arrays in Emulator::Interface - example: emulator.ports[p].devices[d].inputs[i] - example: vector<Medium> media - probably more surprises Major show-stoppers to the next official release: - we need to work on GB core improvements: LY=153/0 case, multiple STAT IRQs case, GBC audio output regs, etc. - we need to re-add software cursors for light guns (Super Scope, Justifier) - after the above, we need to fix the turbo button for the Super Scope I really have no idea how I want to implement the light guns. Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video.

Update to v098r11 release. byuu says: Changelog: - fixed nall/path.hpp compilation issue - fixed ruby/audio/xaudio header declaration compilation issue (again) - cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the file was whitespace overkill) - added null terminator entry to nall/windows/utf8.hpp argc[] array - nall/windows/guid.hpp uses the Windows API for generating the GUID - this should stop all the bug reports where two nall users were generating GUIDs at the exact same second - fixed hiro/cocoa compilation issue with uint# types - fixed major higan/sfc Super Game Boy audio latency issue - fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions - major cleanups to higan/processor/r65816 core - merged emulation/native-mode opcodes - use camel-case naming on memory.hpp functions - simplify address masking code for memory.hpp functions - simplify a few opcodes themselves (avoid redundant copies, etc) - rename regs.* to r.* to match modern convention of other CPU cores - removed device.order<> concept from Emulator::Interface - cores will now do the translation to make the job of the UI easier - fixed plurality naming of arrays in Emulator::Interface - example: emulator.ports[p].devices[d].inputs[i] - example: vector<Medium> media - probably more surprises Major show-stoppers to the next official release: - we need to work on GB core improvements: LY=153/0 case, multiple STAT IRQs case, GBC audio output regs, etc. - we need to re-add software cursors for light guns (Super Scope, Justifier) - after the above, we need to fix the turbo button for the Super Scope I really have no idea how I want to implement the light guns. Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video.

Update to v097r15 release. byuu says: Changelog: - higan now uses Natural<Size>/Integer<Size> for its internal types - Super Famicom emulation now uses uint24 instead of uint for bus addresses (it's a 24-bit bus) - cleaned up gb/apu MMIO writes - cleaned up sfc/coprocessor/msu1 MMIO writes - ~3% speed penalty I've wanted to do that 24-bit bus thing for so long, but have always been afraid of the speed impact. It's probably going to hurt balanced/performance once they compile again, but it wasn't significant enough to harm the accuracy core's frame rate, thankfully. Only lost one frame per second. The GBA core handlers are clearly going to take a lot more work. The bit-ranges will make it substantially easier to handle, though. Lots of 32-bit registers where certain values span multiple bytes, but we have to be able to read/write at byte-granularity.

Update to v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot. My plan for BS-X slotted cartridges is to require a manifest.xml to specify that it has the BS-X slot present. Otherwise, we have to load the ROM into the SNES cartridge class, and parse its header before we can find out if it has one. Screw that. If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.

Update to v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot. My plan for BS-X slotted cartridges is to require a manifest.xml to specify that it has the BS-X slot present. Otherwise, we have to load the ROM into the SNES cartridge class, and parse its header before we can find out if it has one. Screw that. If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.

Update to v099r13 release. byuu says: Changelog: - GB core code cleanup completed - GBA core code cleanup completed - some more cleanup on missed processor/arm functions/variables - fixed FC loading icarus bug - "Load ROM File" icarus functionality restored - minor code unification efforts all around (not perfect yet) - MMIO->IO - mmio.cpp->io.cpp - read,write->readIO,writeIO It's been a very long work in progress ... starting all the way back with v094r09, but the major part of the higan code cleanup is now completed! Of course, it's very important to note that this is only for the basic style: - under_score functions and variables are now camelCase - return-type function-name() are now auto function-name() -> return-type - Natural<T>/Integer<T> replace (u)intT_n types where possible - signed/unsigned are now int/uint - most of the x==true,x==false tests changed to x,!x A lot of spot improvements to consistency, simplicity and quality have gone in along the way, of course. But we'll probably never fully finishing beautifying every last line of code in the entire codebase. Still, this is a really great start. Going forward, WIP diffs should start being smaller and of higher quality once again. I know the joke is, "until my coding style changes again", but ... this was way too stressful, way too time consuming, and way too risky. I'm too old and tired now for extreme upheavel like this again. The only major change I'm slowly mulling over would be renaming the using Natural<T>/Integer<T> = (u)intT; shorthand to something that isn't as easily confused with the (u)int_t types ... but we'll see. I'll definitely continue to change small things all the time, but for the larger picture, I need to just accept the style I have and live with it.

Update to v087r20 release. byuu says: Changelog: - HALT waits 16 cycles before testing IRQs instead of 1 (probably less precise, but provides a massive speedup) [we will need to work on this later] - MMIO regs for CPU/PPU simplified by combining array accesses - custom VRAM/PRAM/OAM read/write functions that emulate 8->16-bit writes - 16-bit PRAM data (decent speedup) - emulated memory access speed (but don't handle non-sequential penalties or PPU access penalties yet) [amazingly, doesn't help speed at all] - misc. code cleanups For this WIP, FPS for Mr. Driller 2 went from 88fps to 172fps. Compatibility should be unchanged. Timers are still an interesting avenue to increase performance, but will be very tough to handle the 16MHz timers with eg a period of 65535 (overflow every single tick.) And that's basically the last major speed boost we'll be able to get. Blending and windowing is going to hurt performance, but it remains to be seen how much.

Update to v087r20 release. byuu says: Changelog: - HALT waits 16 cycles before testing IRQs instead of 1 (probably less precise, but provides a massive speedup) [we will need to work on this later] - MMIO regs for CPU/PPU simplified by combining array accesses - custom VRAM/PRAM/OAM read/write functions that emulate 8->16-bit writes - 16-bit PRAM data (decent speedup) - emulated memory access speed (but don't handle non-sequential penalties or PPU access penalties yet) [amazingly, doesn't help speed at all] - misc. code cleanups For this WIP, FPS for Mr. Driller 2 went from 88fps to 172fps. Compatibility should be unchanged. Timers are still an interesting avenue to increase performance, but will be very tough to handle the 16MHz timers with eg a period of 65535 (overflow every single tick.) And that's basically the last major speed boost we'll be able to get. Blending and windowing is going to hurt performance, but it remains to be seen how much.

Cydrak is absolutely amazingly awesome and patient. This really wouldn't be happening without him. Also fixed some things from my end, including greatly improved sprite priorities, and a much better priority sorter. Mr. Driller looks a lot better now.

Update to v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot. My plan for BS-X slotted cartridges is to require a manifest.xml to specify that it has the BS-X slot present. Otherwise, we have to load the ROM into the SNES cartridge class, and parse its header before we can find out if it has one. Screw that. If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.

Update to v087r15 release. byuu says: Added linear (eg non-affine) sprite rendering, 4bpp and 8bpp with hflip and vflip. Nothing else. You can now see the Nintendo logo and Gameboy text at the end of the BIOS. It's a start =)

Update to v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot. My plan for BS-X slotted cartridges is to require a manifest.xml to specify that it has the BS-X slot present. Otherwise, we have to load the ROM into the SNES cartridge class, and parse its header before we can find out if it has one. Screw that. If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.

Update to v101r25 release. byuu says: Changelog: - Makefile: added $(windres), -lpthread to Windows port - GBA: WAITCNT.prefetch is not writable (should fix Donkey Kong: King of Swing) \[endrift\] - SMS: fixed hcounter shift value \[hex\_usr\] - SMS: emulated interrupts (reset button isn't hooked up anywhere, not sure where to put it yet) This WIP actually took a really long time because the documentation on SMS interrupts was all over the place. I'm hoping I've emulated them correctly, but I honestly have no idea. It's based off my best understanding from four or five different sources. So it's probably quite buggy. However, a few interrupts fire in Sonic the Hedgehog, so that's something to start with. Now I just have to hope I've gotten some games far enough in that I can start seeing some data in the VDP VRAM. I need that before I can start emulating graphics mode 4 to get some actual screen output. Or I can just say to hell with it and use a "Hello World" test ROM. That'd probably be smarter.

Update to v087r28 release. byuu says: Be sure to run make install, and move required images to their appropriate system profile folders. I still have no warnings in place if those images aren't present. Changelog: - OBJ mosaic should hopefully be emulated correctly now (thanks to krom and Cydrak for testing the hardware behavior) - emulated dummy serial registers, fixes Sonic Advance (you may still need to specify 512KB FlashROM with an appropriate ID, I used Panaonic's) - GBA core exits scheduler (PPU thread) and calls interface->videoRefresh() from main thread (not required, just nice) - SRAM, FRAM, EEPROM and FlashROM initialized to 0xFF if it does not exist (probably not needed, but FlashROM likes to reset to 0xFF anyway) - GBA manifest.xml for file-mode will now use "gamename.xml" instead of "gamename.gba.xml" - started renaming "NES" to "Famicom" and "SNES" to "Super Famicom" in the GUI (may or may not change source code in the long-term) - removed target-libsnes/ - added profile/ Profiles are the major new feature. So far we have: Famicom.sys/{nothing (yet?)} Super Famicom.sys/{ipl.rom} Game Boy.sys/{boot.rom} Game Boy Color.sys/{boot.rom} Game Boy Advance.sys/{bios.rom[not included]} Super Game Boy.sfc/{boot.rom,program.rom[not included]} BS-X Satellaview.sfc/{program.rom,bsx.ram,bsx.pram} Sufami Turbo.sfc/{program.rom} The SGB, BSX and ST cartridges ask you to load GB, BS or ST cartridges directly now. No slot loader for them. So the obvious downsides: you can't quickly pick between different SGB BIOSes, but why would you want to? Just use SGB2/JP. It's still possible, so I'll sacrifice a little complexity for a rare case to make it a lot easier for the more common case. ST cartridges currently won't let you load the secondary slot. BS-X Town cart is the only useful game to load with nothing in the slot, but only barely, since games are all seeded on flash and not on PSRAM images. We can revisit a way to boot the BIOS directly if and when we get the satellite uplink emulated and data can be downloaded onto the PSRAM :P BS-X slotted cartridges still require the secondary slot. My plan for BS-X slotted cartridges is to require a manifest.xml to specify that it has the BS-X slot present. Otherwise, we have to load the ROM into the SNES cartridge class, and parse its header before we can find out if it has one. Screw that. If it's in the XML, I can tell before loading the ROM if I need to present you with an optional slot loading dialog. I will probably do something similar for Sufami Turbo. Not all games even work with a secondary slot, so why ask you to load a second slot for them? Let the XML request a second slot. A complete Sufami Turbo ROM set will be trivial anyway. Not sure how I want to do the sub dialog yet. We want basic file loading, but we don't want it to look like the dialog 'didn't do anything' if it pops back open immediately again. Maybe change the background color of the dialog to a darker gray? Tacky, but it'd give you the visual cue without the need for some subtle text changes.
