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.

auto CPU::readIO(uint32 addr) -> uint8 {
Update to v103r07 release. byuu says: Changelog: - gba/cpu: massive code cleanup effort - gba/cpu: DMA can run in between active instructions¹ - gba/cpu: added two-cycle startup delay between DMA activation and DMA transfers² - processor/spc700: BBC, BBC, CBNE cycle 4 is an idle cycle - processor/spc700: ADDW, SUBW, MOVW (read) cycle 4 is an idle cycle ¹: unfortunately, this causes yet another performance penalty for the poor GBA core =( Also, I think I may have missed disabling DMAs while the CPU is stopped. I'll fix that in the next WIP. ²: I put the waiting counter decrement at the wrong place, so this doesn't actually work. Needs to be more like this:    auto CPU::step(uint clocks) -> void {      for(auto _ : range(clocks)) {        for(auto& timer : this->timer) timer.run();        for(auto& dma : this->dma) if(dma.active && dma.waiting) dma.waiting--;        context.clock++;      }      ...    auto CPU::DMA::run() -> bool {      if(cpu.stopped() || !active || waiting) return false;      transfer();      if(irq) cpu.irq.flag |= CPU::Interrupt::DMA0 << id;      if(drq && id == 3) cpu.irq.flag |= CPU::Interrupt::Cartridge;      return true;    } Of course, the real fix will be restructuring how DMA works, so that it's always running in parallel with the CPU instead of this weird design where it tries to run all channels in some kind of loop until no channels are active anymore whenever one channel is activated. Not really sure how to design that yet, however.

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 v102r24 release. byuu says Changelog: - FC: fixed three MOS6502 regressions [hex\_usr] - GBA: return fetched instruction instead of 0 for unmapped MMIO (passes all of endrift's I/O tests) - MD: fix VDP control port read Vblank bit to test screen height instead of hard-code 240 (fixes Phantasy Star IV) - MD: swap USP,SSP when executing an exception (allows Super Street Fighter II to run; but no sprites visible yet) - MD: grant 68K access to Z80 bus on reset (fixes vdpdoc demo ROM from freezing immediately) - SFC: reads from $00-3f,80-bf:4000-43ff no longer update MDR [p4plus2] - SFC: massive, eight-hour cleanup of WDC65816 CPU core ... still not complete The big change this time around is the SFC CPU core. I've renamed everything from R65816 to WDC65816, and then went through and tried to clean up the code as much as possible. This core is so much larger than the 6502 core that I chose cleaning up the code to rewriting it. First off, I really don't care for the BitRange style functionality. It was an interesting experiment, but its fatal flaw are that the types are just bizarre, which makes them hard to pass around generically to other functions as arguments. So I went back to the list of bools for flags, and union/struct blocks for the registers. Next, I renamed all of the functions to be more descriptive: eg `op_read_idpx_w` becomes `instructionIndexedIndirectRead16`. `op_adc_b` becomes `algorithmADC8`. And so forth. I eliminated about ten instructions because they were functionally identical sans the index, so I just added a uint index=0 parameter to said functions. I added a few new ones (adjust→INC,DEC; pflag→REP,SEP) where it seemed appropriate. I cleaned up the disaster of the instruction switch table into something a whole lot more elegant without all the weird argument decoding nonsense (still need M vs X variants to avoid having to have 4-5 separate switch tables, but all the F/I flags are gone now); and made some things saner, like the flag clear/set and branch conditions, now that I have normal types for flags and registers once again. I renamed all of the memory access functions to be more descriptive to what they're doing: eg writeSP→push, readPC→fetch, writeDP→writeDirect, etc. Eliminated some of the special read/write modes that were only used in one single instruction. I started to clean up some of the actual instructions themselves, but haven't really accomplished much here. The big thing I want to do is get rid of the global state (aa, rd, iaddr, etc) and instead use local variables like I am doing with my other 65xx CPU cores now. But this will take some time ... the algorithm functions depend on rd to be set to work on them, rather than taking arguments. So I'll need to rework that. And then lastly, the disassembler is still a mess. I want to finish the CPU cleanups, and then post a new WIP, and then rewrite the disassembler after that. The reason being ... I want a WIP that can generate identical trace logs to older versions, in case the CPU cleanup causes any regressions. That way I can more easily spot the errors. Oh ... and a bit of good news. v102 was running at ~140fps on the SNES core. With the new support to suspend/resume WAI/STP, plus the internal CPU registers not updating the MDR, the framerate dropped to ~132fps. But with the CPU cleanups, performance went back to ~140fps. So, hooray. Of course, without those two other improvements, we'd have ended up at possibly ~146-148fps, but oh well.

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.

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.

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.

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.

Update to v102r24 release. byuu says Changelog: - FC: fixed three MOS6502 regressions [hex\_usr] - GBA: return fetched instruction instead of 0 for unmapped MMIO (passes all of endrift's I/O tests) - MD: fix VDP control port read Vblank bit to test screen height instead of hard-code 240 (fixes Phantasy Star IV) - MD: swap USP,SSP when executing an exception (allows Super Street Fighter II to run; but no sprites visible yet) - MD: grant 68K access to Z80 bus on reset (fixes vdpdoc demo ROM from freezing immediately) - SFC: reads from $00-3f,80-bf:4000-43ff no longer update MDR [p4plus2] - SFC: massive, eight-hour cleanup of WDC65816 CPU core ... still not complete The big change this time around is the SFC CPU core. I've renamed everything from R65816 to WDC65816, and then went through and tried to clean up the code as much as possible. This core is so much larger than the 6502 core that I chose cleaning up the code to rewriting it. First off, I really don't care for the BitRange style functionality. It was an interesting experiment, but its fatal flaw are that the types are just bizarre, which makes them hard to pass around generically to other functions as arguments. So I went back to the list of bools for flags, and union/struct blocks for the registers. Next, I renamed all of the functions to be more descriptive: eg `op_read_idpx_w` becomes `instructionIndexedIndirectRead16`. `op_adc_b` becomes `algorithmADC8`. And so forth. I eliminated about ten instructions because they were functionally identical sans the index, so I just added a uint index=0 parameter to said functions. I added a few new ones (adjust→INC,DEC; pflag→REP,SEP) where it seemed appropriate. I cleaned up the disaster of the instruction switch table into something a whole lot more elegant without all the weird argument decoding nonsense (still need M vs X variants to avoid having to have 4-5 separate switch tables, but all the F/I flags are gone now); and made some things saner, like the flag clear/set and branch conditions, now that I have normal types for flags and registers once again. I renamed all of the memory access functions to be more descriptive to what they're doing: eg writeSP→push, readPC→fetch, writeDP→writeDirect, etc. Eliminated some of the special read/write modes that were only used in one single instruction. I started to clean up some of the actual instructions themselves, but haven't really accomplished much here. The big thing I want to do is get rid of the global state (aa, rd, iaddr, etc) and instead use local variables like I am doing with my other 65xx CPU cores now. But this will take some time ... the algorithm functions depend on rd to be set to work on them, rather than taking arguments. So I'll need to rework that. And then lastly, the disassembler is still a mess. I want to finish the CPU cleanups, and then post a new WIP, and then rewrite the disassembler after that. The reason being ... I want a WIP that can generate identical trace logs to older versions, in case the CPU cleanup causes any regressions. That way I can more easily spot the errors. Oh ... and a bit of good news. v102 was running at ~140fps on the SNES core. With the new support to suspend/resume WAI/STP, plus the internal CPU registers not updating the MDR, the framerate dropped to ~132fps. But with the CPU cleanups, performance went back to ~140fps. So, hooray. Of course, without those two other improvements, we'd have ended up at possibly ~146-148fps, but oh well.

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 v103r07 release. byuu says: Changelog: - gba/cpu: massive code cleanup effort - gba/cpu: DMA can run in between active instructions¹ - gba/cpu: added two-cycle startup delay between DMA activation and DMA transfers² - processor/spc700: BBC, BBC, CBNE cycle 4 is an idle cycle - processor/spc700: ADDW, SUBW, MOVW (read) cycle 4 is an idle cycle ¹: unfortunately, this causes yet another performance penalty for the poor GBA core =( Also, I think I may have missed disabling DMAs while the CPU is stopped. I'll fix that in the next WIP. ²: I put the waiting counter decrement at the wrong place, so this doesn't actually work.

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.

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 v103r07 release. byuu says: Changelog: - gba/cpu: massive code cleanup effort - gba/cpu: DMA can run in between active instructions¹ - gba/cpu: added two-cycle startup delay between DMA activation and DMA transfers² - processor/spc700: BBC, BBC, CBNE cycle 4 is an idle cycle - processor/spc700: ADDW, SUBW, MOVW (read) cycle 4 is an idle cycle ¹: unfortunately, this causes yet another performance penalty for the poor GBA core =( Also, I think I may have missed disabling DMAs while the CPU is stopped. I'll fix that in the next WIP. ²: I put the waiting counter decrement at the wrong place, so this doesn't actually work. Needs to be more like this:    auto CPU::step(uint clocks) -> void {      for(auto _ : range(clocks)) {        for(auto& timer : this->timer) timer.run();        for(auto& dma : this->dma) if(dma.active && dma.waiting) dma.waiting--;        context.clock++;      }      ...    auto CPU::DMA::run() -> bool {      if(cpu.stopped() || !active || waiting) return false;      transfer();      if(irq) cpu.irq.flag |= CPU::Interrupt::DMA0 << id;      if(drq && id == 3) cpu.irq.flag |= CPU::Interrupt::Cartridge;      return true;    } Of course, the real fix will be restructuring how DMA works, so that it's always running in parallel with the CPU instead of this weird design where it tries to run all channels in some kind of loop until no channels are active anymore whenever one channel is activated. Not really sure how to design that yet, however.

Update to v087r18 release. byuu says: Merged Cydrak's r17c changes: - BG affine mode added - BG bitmap mode added - OBJ affine mode added - fixed IRQ bug in THUMB mode (fixed almost every game) - timers added (broke almost every game, whee.) 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.

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.

//SIOMLT_SEND (SIODATA8)
Update to v103r07 release. byuu says: Changelog: - gba/cpu: massive code cleanup effort - gba/cpu: DMA can run in between active instructions¹ - gba/cpu: added two-cycle startup delay between DMA activation and DMA transfers² - processor/spc700: BBC, BBC, CBNE cycle 4 is an idle cycle - processor/spc700: ADDW, SUBW, MOVW (read) cycle 4 is an idle cycle ¹: unfortunately, this causes yet another performance penalty for the poor GBA core =( Also, I think I may have missed disabling DMAs while the CPU is stopped. I'll fix that in the next WIP. ²: I put the waiting counter decrement at the wrong place, so this doesn't actually work. Needs to be more like this:    auto CPU::step(uint clocks) -> void {      for(auto _ : range(clocks)) {        for(auto& timer : this->timer) timer.run();        for(auto& dma : this->dma) if(dma.active && dma.waiting) dma.waiting--;        context.clock++;      }      ...    auto CPU::DMA::run() -> bool {      if(cpu.stopped() || !active || waiting) return false;      transfer();      if(irq) cpu.irq.flag |= CPU::Interrupt::DMA0 << id;      if(drq && id == 3) cpu.irq.flag |= CPU::Interrupt::Cartridge;      return true;    } Of course, the real fix will be restructuring how DMA works, so that it's always running in parallel with the CPU instead of this weird design where it tries to run all channels in some kind of loop until no channels are active anymore whenever one channel is activated. Not really sure how to design that yet, however.

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.

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.

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.

//MEMCNT_H
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 ... To compile on Windows: 1. change nall/string/platform.hpp line 47 to return slice(result, 0, 3); 2. change ruby/video.wgl.cpp line 72 to auto lock(uint32_t*& data, uint& pitch, uint width, uint height) -> bool { 3. add this line to the very top of hiro/windows/header.cpp: #define boolean FuckYouMicrosoft

Update to v103r07 release. byuu says: Changelog: - gba/cpu: massive code cleanup effort - gba/cpu: DMA can run in between active instructions¹ - gba/cpu: added two-cycle startup delay between DMA activation and DMA transfers² - processor/spc700: BBC, BBC, CBNE cycle 4 is an idle cycle - processor/spc700: ADDW, SUBW, MOVW (read) cycle 4 is an idle cycle ¹: unfortunately, this causes yet another performance penalty for the poor GBA core =( Also, I think I may have missed disabling DMAs while the CPU is stopped. I'll fix that in the next WIP. ²: I put the waiting counter decrement at the wrong place, so this doesn't actually work. Needs to be more like this:    auto CPU::step(uint clocks) -> void {      for(auto _ : range(clocks)) {        for(auto& timer : this->timer) timer.run();        for(auto& dma : this->dma) if(dma.active && dma.waiting) dma.waiting--;        context.clock++;      }      ...    auto CPU::DMA::run() -> bool {      if(cpu.stopped() || !active || waiting) return false;      transfer();      if(irq) cpu.irq.flag |= CPU::Interrupt::DMA0 << id;      if(drq && id == 3) cpu.irq.flag |= CPU::Interrupt::Cartridge;      return true;    } Of course, the real fix will be restructuring how DMA works, so that it's always running in parallel with the CPU instead of this weird design where it tries to run all channels in some kind of loop until no channels are active anymore whenever one channel is activated. Not really sure how to design that yet, however.
