Update to v095r05 release. byuu says: Changelog: - GBA: lots of emulation improvements - PPU PRAM is 16-bits wide - DMA masks &~1/Half, &~3/Word - VRAM OBJ 8-bit writes are ignored - OAM 8-bit writes are ignored - BGnCNT unused bits are writable* - BG(0,1)CNT can't set the d13 - BLDALPHA is readable (fixes Donkey Kong Country, etc) - SNES: lots of code cleanups - sfc/chip => sfc/coprocessor - UI: save most recent controller selection GBA test scores: 1552/1552, 37/38, 1020/1260 (* forgot to add the value to the read function, so endrift's I/O tests for them will fail. Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.

auto PPU::interlace() const -> bool {
Update to v068r24 release. (there was no r23 release posted to the WIP thread) byuu says: Fixes OAM latchdata for all 3 cores and CGRAM address invalidation for the accuracy core (the only one that really does it because it needs cycle PPU timing.) Also removes the OAM/CGRAM read/write functions to put them inside the actual MMIO functions. Easier to handle all the special cases that way. VRAM is a bit more annoying since there's two read and two write functions. This should fix battletech/mechwarrior 3050 palette at least.

Update to v092r09 release. byuu says: This will be another massive diff from the previous version. 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.

auto PPU::vram_read(uint addr) -> uint8 {
Update to v094r05 release. byuu says: Commands can be prefixed with: (cpu|smp|ppu|dsp|apu|vram|oam|cgram)/ to set their source. Eg "vram/hex 0800" or "smp/breakpoints.append execute ffc0"; default is cpu. These overlap a little bit in odd ways, but that's just the way the SNES works: it's not a very orthogonal system. CPU is both a processor and the main bus (ROM, RAM, WRAM, etc), APU is the shared memory by the SMP+DSP (eg use it to catch writes from either chip); PPU probably won't ever be used since it's broken down into three separate buses (VRAM, OAM, CGRAM), but DSP could be useful for tracking bugs like we found in Koushien 2 with the DSP echo buffer corrupting SMP opcodes. Technically the PPU memory pools are only ever tripped by the CPU poking at them, as the PPU doesn't ever write. I now have run.for, run.to, step.for, step.to. The difference is that run only prints the next instruction after running, whereas step prints all of the instructions along the way as well. run.to acts the same as "step over" here. Although it's not quite as nice, since you have to specify the address of the next instruction. Logging the Field/Vcounter/Hcounter on instruction listings now, good for timing information. Added in the tracer mask, as well as memory export, as well as VRAM/OAM/CGRAM/SMP read/write/execute breakpoints, as well as an APU usage map (it tracks DSP reads/writes separately, although I don't currently have debugger callbacks on DSP accesses just yet.) Have not hooked up actual SMP debugging just yet, but I plan to soon. Still thinking about how I want to allow / block interleaving of instructions (terminal output and tracing.) So ... remaining tasks at this point: - full SMP debugging - CPU+SMP interleave support - aliases - hotkeys - save states (will be kind of tricky ... will have to suppress breakpoints during synchronization, or abort a save in a break event.) - keep track of window geometry between runs

uint8 data = 0x00;
Update to v068r12 release. (there was no r11 release posted to the WIP thread) byuu says: This took ten hours of mind boggling insanity to pull off. It upgrades the S-PPU dot-based renderer to fetch one tile, and then output all of its pixels before fetching again. It sounds easy enough, but it's insanely difficult. I ended up taking one small shortcut, in that rather than fetch at -7, I fetch at the first instance where a tile is needed to plot to x=0. So if you have {-3 to +4 } as a tile, it fetches at -3. That won't work so well on hardware, if two BGs fetch at the same X offset, they won't have time. I have had no luck staggering the reads at BG1=-7, BG3=-5, etc. While I can shift and fetch just fine, what happens is that when a new tile is fetched in, that gives a new palette, priority, etc; and this ends up happening between two tiles which results in the right-most edges of the screen ending up with the wrong colors and such. Offset-per-tile is cheap as always. Although looking at it, I'm not sure how BG3 could pre-fetch, especially with the way one or two OPT modes can fetch two tiles. There's no magic in Hoffset caching yet, so the SMW1 pixel issue is still there. Mode 7 got a bugfix, it was off-by-one horizontally from the mosaic code. After re-designing the BG mosaic, I ended up needing a separate mosaic for Mode7, and in the process I fixed that bug. The obvious change is that the Chrono Trigger Mode7->Mode2 transition doesn't cause the pendulum to jump anymore. Windows were simplified just a tad. The range testing is shared for all modes now. Ironically, it's a bit slower, but I'll take less code over more speed for the accuracy core. Speaking of speed, because there's so much less calculations per pixel for BGs, performance for the entire emulator has gone up by 30% in the accuracy core. Pretty neat overall, I can maintain 60fps in all but, yeah you can guess can't you?

Added in the tracer mask, as well as memory export, as well as VRAM/OAM/CGRAM/SMP read/write/execute breakpoints, as well as an APU usage map (it tracks DSP reads/writes separately, although I don't currently have debugger callbacks on DSP accesses just yet.) Have not hooked up actual SMP debugging just yet, but I plan to soon. Still thinking about how I want to allow / block interleaving of instructions (terminal output and tracing.) So ... remaining tasks at this point: - full SMP debugging - CPU+SMP interleave support - aliases - hotkeys - save states (will be kind of tricky ... will have to suppress breakpoints during synchronization, or abort a save in a break event.) - keep track of window geometry between runs

Update to v085r08 release. byuu says: Changelog: - follow the Laevateinn topic to get most of it - also added NMI, IRQ step buttons to CPU debugger - also added trace masking + trace mask reset - also added memory export - cartridge loading is entirely folder-based now FitzRoy, I'll go ahead and make a second compromise with you for v086: I'll match the following: /path/to/SNES.sfc/*.sfc /path/to/NES.fc/*.prg, *.chr (split format) /path/to/NES.fc/*.fc (merged format) /path/to/GB.gb/*.gb /path/to/GBC.gbc/*.gbc Condition will be that there can only be one of each file. If there's more than one, it'll abort. That lets me name my ROMs as "Game.fc/Game.fc", and you can name yours as "Game.fc/cartridge.prg, cartridge.chr". Or whatever you want. We'll just go with that, see what fares out as the most popular, and then restrict it back to that method. The folder must have the .fc, etc extension though. That will be how we avoid false-positive folder matches. [Editor's note - the Laevateinn topic mentions these changes for v085r08: Added SMP/PPU breakpoints, SMP debugger, SMP stepping / tracing, memory editing on APU-bus / VRAM / OAM / CGRAM, save state menu, WRAM mirroring on breakpoints, protected MMIO memory regions (otherwise, viewing $002100 could crash your game.) Major missing components: - trace mask - trace mask clear / usage map clear - window geometry caching / sizing improvements - VRAM viewer - properties viewer - working memory export button The rest will most likely appear after v086 is released. ]

Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.

Eg "vram/hex 0800" or "smp/breakpoints.append execute ffc0"; default is cpu. These overlap a little bit in odd ways, but that's just the way the SNES works: it's not a very orthogonal system. CPU is both a processor and the main bus (ROM, RAM, WRAM, etc), APU is the shared memory by the SMP+DSP (eg use it to catch writes from either chip); PPU probably won't ever be used since it's broken down into three separate buses (VRAM, OAM, CGRAM), but DSP could be useful for tracking bugs like we found in Koushien 2 with the DSP echo buffer corrupting SMP opcodes.

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 v068r12 release. (there was no r11 release posted to the WIP thread) byuu says: This took ten hours of mind boggling insanity to pull off. It upgrades the S-PPU dot-based renderer to fetch one tile, and then output all of its pixels before fetching again. It sounds easy enough, but it's insanely difficult. I ended up taking one small shortcut, in that rather than fetch at -7, I fetch at the first instance where a tile is needed to plot to x=0. So if you have {-3 to +4 } as a tile, it fetches at -3. That won't work so well on hardware, if two BGs fetch at the same X offset, they won't have time. I have had no luck staggering the reads at BG1=-7, BG3=-5, etc. While I can shift and fetch just fine, what happens is that when a new tile is fetched in, that gives a new palette, priority, etc; and this ends up happening between two tiles which results in the right-most edges of the screen ending up with the wrong colors and such. Offset-per-tile is cheap as always. Although looking at it, I'm not sure how BG3 could pre-fetch, especially with the way one or two OPT modes can fetch two tiles. There's no magic in Hoffset caching yet, so the SMW1 pixel issue is still there. Mode 7 got a bugfix, it was off-by-one horizontally from the mosaic code. After re-designing the BG mosaic, I ended up needing a separate mosaic for Mode7, and in the process I fixed that bug. The obvious change is that the Chrono Trigger Mode7->Mode2 transition doesn't cause the pendulum to jump anymore. Windows were simplified just a tad. The range testing is shared for all modes now. Ironically, it's a bit slower, but I'll take less code over more speed for the accuracy core. Speaking of speed, because there's so much less calculations per pixel for BGs, performance for the entire emulator has gone up by 30% in the accuracy core. Pretty neat overall, I can maintain 60fps in all but, yeah you can guess can't you?

Because it's shared by the controller and expansion port, it ends up sorted first in the list.

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.

Update to v068r24 release. (there was no r23 release posted to the WIP thread) byuu says: Fixes OAM latchdata for all 3 cores and CGRAM address invalidation for the accuracy core (the only one that really does it because it needs cycle PPU timing.) Also removes the OAM/CGRAM read/write functions to put them inside the actual MMIO functions. Easier to handle all the special cases that way. VRAM is a bit more annoying since there's two read and two write functions. This should fix battletech/mechwarrior 3050 palette at least.

Update to v085r08 release. byuu says: Changelog: - follow the Laevateinn topic to get most of it - also added NMI, IRQ step buttons to CPU debugger - also added trace masking + trace mask reset - also added memory export - cartridge loading is entirely folder-based now FitzRoy, I'll go ahead and make a second compromise with you for v086: I'll match the following: /path/to/SNES.sfc/*.sfc /path/to/NES.fc/*.prg, *.chr (split format) /path/to/NES.fc/*.fc (merged format) /path/to/GB.gb/*.gb /path/to/GBC.gbc/*.gbc Condition will be that there can only be one of each file. If there's more than one, it'll abort. That lets me name my ROMs as "Game.fc/Game.fc", and you can name yours as "Game.fc/cartridge.prg, cartridge.chr". Or whatever you want. We'll just go with that, see what fares out as the most popular, and then restrict it back to that method. The folder must have the .fc, etc extension though. That will be how we avoid false-positive folder matches. [Editor's note - the Laevateinn topic mentions these changes for v085r08: Added SMP/PPU breakpoints, SMP debugger, SMP stepping / tracing, memory editing on APU-bus / VRAM / OAM / CGRAM, save state menu, WRAM mirroring on breakpoints, protected MMIO memory regions (otherwise, viewing $002100 could crash your game.) Major missing components: - trace mask - trace mask clear / usage map clear - window geometry caching / sizing improvements - VRAM viewer - properties viewer - working memory export button The rest will most likely appear after v086 is released. ]

Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.

sprite.regs.main_enable = data & 0x10;
Update to v068r12 release. (there was no r11 release posted to the WIP thread) byuu says: This took ten hours of mind boggling insanity to pull off. It upgrades the S-PPU dot-based renderer to fetch one tile, and then output all of its pixels before fetching again. It sounds easy enough, but it's insanely difficult. I ended up taking one small shortcut, in that rather than fetch at -7, I fetch at the first instance where a tile is needed to plot to x=0. So if you have {-3 to +4 } as a tile, it fetches at -3. That won't work so well on hardware, if two BGs fetch at the same X offset, they won't have time. I have had no luck staggering the reads at BG1=-7, BG3=-5, etc. While I can shift and fetch just fine, what happens is that when a new tile is fetched in, that gives a new palette, priority, etc; and this ends up happening between two tiles which results in the right-most edges of the screen ending up with the wrong colors and such. Offset-per-tile is cheap as always. Although looking at it, I'm not sure how BG3 could pre-fetch, especially with the way one or two OPT modes can fetch two tiles. There's no magic in Hoffset caching yet, so the SMW1 pixel issue is still there. Mode 7 got a bugfix, it was off-by-one horizontally from the mosaic code. After re-designing the BG mosaic, I ended up needing a separate mosaic for Mode7, and in the process I fixed that bug. The obvious change is that the Chrono Trigger Mode7->Mode2 transition doesn't cause the pendulum to jump anymore. Windows were simplified just a tad. The range testing is shared for all modes now. Ironically, it's a bit slower, but I'll take less code over more speed for the accuracy core. Speaking of speed, because there's so much less calculations per pixel for BGs, performance for the entire emulator has gone up by 30% in the accuracy core. Pretty neat overall, I can maintain 60fps in all but, yeah you can guess can't you?

Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.

Update to v068r24 release. (there was no r23 release posted to the WIP thread) byuu says: Fixes OAM latchdata for all 3 cores and CGRAM address invalidation for the accuracy core (the only one that really does it because it needs cycle PPU timing.) Also removes the OAM/CGRAM read/write functions to put them inside the actual MMIO functions. Easier to handle all the special cases that way. VRAM is a bit more annoying since there's two read and two write functions. This should fix battletech/mechwarrior 3050 palette at least.

If there's more than one, it'll abort. That lets me name my ROMs as "Game.fc/Game.fc", and you can name yours as "Game.fc/cartridge.prg, cartridge.chr". Or whatever you want. We'll just go with that, see what fares out as the most popular, and then restrict it back to that method. The folder must have the .fc, etc extension though. That will be how we avoid false-positive folder matches. [Editor's note - the Laevateinn topic mentions these changes for v085r08: Added SMP/PPU breakpoints, SMP debugger, SMP stepping / tracing, memory editing on APU-bus / VRAM / OAM / CGRAM, save state menu, WRAM mirroring on breakpoints, protected MMIO memory regions (otherwise, viewing $002100 could crash your game.) Major missing components: - trace mask - trace mask clear / usage map clear - window geometry caching / sizing improvements - VRAM viewer - properties viewer - working memory export button The rest will most likely appear after v086 is released. ]

(there was no r23 release posted to the WIP thread) byuu says: Fixes OAM latchdata for all 3 cores and CGRAM address invalidation for the accuracy core (the only one that really does it because it needs cycle PPU timing.) Also removes the OAM/CGRAM read/write functions to put them inside the actual MMIO functions. Easier to handle all the special cases that way. VRAM is a bit more annoying since there's two read and two write functions. This should fix battletech/mechwarrior 3050 palette at least.

Update to v068r12 release. (there was no r11 release posted to the WIP thread) byuu says: This took ten hours of mind boggling insanity to pull off. It upgrades the S-PPU dot-based renderer to fetch one tile, and then output all of its pixels before fetching again. It sounds easy enough, but it's insanely difficult. I ended up taking one small shortcut, in that rather than fetch at -7, I fetch at the first instance where a tile is needed to plot to x=0. So if you have {-3 to +4 } as a tile, it fetches at -3. That won't work so well on hardware, if two BGs fetch at the same X offset, they won't have time. I have had no luck staggering the reads at BG1=-7, BG3=-5, etc. While I can shift and fetch just fine, what happens is that when a new tile is fetched in, that gives a new palette, priority, etc; and this ends up happening between two tiles which results in the right-most edges of the screen ending up with the wrong colors and such. Offset-per-tile is cheap as always. Although looking at it, I'm not sure how BG3 could pre-fetch, especially with the way one or two OPT modes can fetch two tiles. There's no magic in Hoffset caching yet, so the SMW1 pixel issue is still there. Mode 7 got a bugfix, it was off-by-one horizontally from the mosaic code. After re-designing the BG mosaic, I ended up needing a separate mosaic for Mode7, and in the process I fixed that bug. The obvious change is that the Chrono Trigger Mode7->Mode2 transition doesn't cause the pendulum to jump anymore. Windows were simplified just a tad. The range testing is shared for all modes now. Ironically, it's a bit slower, but I'll take less code over more speed for the accuracy core. Speaking of speed, because there's so much less calculations per pixel for BGs, performance for the entire emulator has gone up by 30% in the accuracy core. Pretty neat overall, I can maintain 60fps in all but, yeah you can guess can't you?

Update to v095r05 release. byuu says: Changelog: - GBA: lots of emulation improvements - PPU PRAM is 16-bits wide - DMA masks &~1/Half, &~3/Word - VRAM OBJ 8-bit writes are ignored - OAM 8-bit writes are ignored - BGnCNT unused bits are writable* - BG(0,1)CNT can't set the d13 - BLDALPHA is readable (fixes Donkey Kong Country, etc) - SNES: lots of code cleanups - sfc/chip => sfc/coprocessor - UI: save most recent controller selection GBA test scores: 1552/1552, 37/38, 1020/1260 (* forgot to add the value to the read function, so endrift's I/O tests for them will fail. Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.

Update to v092r09 release. byuu says: This will be another massive diff from the previous version. 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.
