Update to v102r26 release. byuu says: Changelog: - md/ym2612: initialize DAC sample to center volume [Cydrak] - processor/arm: add accumulate mode extra cycle to mlal [Jonas Quinn] - processor/huc6280: split off algorithms, improve naming of functions - processor/mos6502: split off algorithms - processor/spc700: major revamp of entire core (~50% completed) - processor/wdc65816: fixed several bugs introduced by rewrite For the SPC700, this turns out to be very old code as well, with global object state variables, those annoying `{Boolean,Natural}BitField` types, `under_case` naming conventions, heavily abbreviated function names, etc. I'm working to get the code to be in the same design as the MOS6502, HuC6280, WDC65816 cores, since they're all extremely similar in terms of architectural design (the SPC700 is more of an off-label reimplementation of a 6502 core, but still.) The main thing left is that about 90% of the actual instructions still need to be adapted to not use the internal state (`aa`, `rd`, `dp`, `sp`, `bit` variables.) I wanted to finish this today, but ran out of time before work. I wouldn't suggest too much testing just yet. We should wait until the SPC700 core is finished for that. However, if some does want to and spots regressions, please let me know.

Update to v101r31 release. byuu says: Changelog: - converted Emulator::Interface::Bind to Emulator::Platform - temporarily disabled SGB hooks - SMS: emulated Game Gear palette (latching word-write behavior not implemented yet) - SMS: emulated Master System 'Reset' button, Game Gear 'Start' button - SMS: removed reset() functionality, driven by the mappable input now instead - SMS: split interface class in two: one for Master System, one for Game Gear - SMS: emulated Game Gear video cropping to 160x144 - PCE: started on HuC6280 CPU core—so far only registers, NOP instruction has been implemented Errata: - Super Game Boy support is broken and thus disabled - if you switch between Master System and Game Gear without restarting, bad things happen: - SMS→GG, no video output on the GG - GG→SMS, no input on the SMS I'm not sure what's causing the SMS\<-\>GG switch bug, having a hard time debugging it. Help would be very much appreciated, if anyone's up for it. Otherwise I'll keep trying to track it down on my end.

Update to v101r34 release. byuu says: Changelog: - PCE: emulated gamepad polling - PCE: emulated CPU interrupt sources - PCE: emulated timer - PCE: smarter emulation of ST0,ST1,ST2 instructions - PCE: better structuring of CPU, VDP IO registers - PCE: connected palette generation to the interface - PCE: emulated basic VDC timing - PCE: emulated VDC Vblank, Coincidence, and DMA completion IRQs - PCE: emulated VRAM, SATB DMA transfers - PCE: emulated VDC I/O registers Everything I've implemented today likely has lots of bugs, and is untested for obvious reasons. So basically, after I fix many horrendous bugs, it should now be possible to implement the VDC and start getting graphical output.

Update to v102 release. byuu says (in the public announcement): This release adds very preliminary emulation of the Sega Master System (Mark III), Sega Game Gear, Sega Mega Drive (Genesis), and NEC PC Engine (Turbografx-16). These cores do not yet offer sound emulation, save states or cheat codes. I'm always very hesitant to release a new emulation core in its alpha stages, as in the past this has resulted in lasting bad impressions of cores that have since improved greatly. For instance, the Game Boy Advance emulation offered today is easily the second most accurate around, yet it is still widely judged by its much older alpha implementation. However, it's always been tradition with higan to not hold onto code in secret. Rather than delay future releases for another year or two, I'll put my faith in you all to understand that the emulation of these systems will improve over time. I hope that by releasing things as they are now, I might be able to receive some much needed assistance in improving these cores, as the documentation for these new systems is very much less than ideal. byuu says (in the WIP forum): Changelog: - PCE: latch background scroll registers (fixes Neutopia scrolling) - PCE: clip background attribute table scrolling (fixes Blazing Lazers scrolling) - PCE: support background/sprite enable/disable bits - PCE: fix large sprite indexing (fixes Blazing Lazers title screen sprites) - HuC6280: wrap zeropage accesses to never go beyond $20xx - HuC6280: fix alternating addresses for block move instructions (fixes Neutopia II) - HuC6280: block move instructions save and restore A,X,Y registers - HuC6280: emulate BCD mode (may not be 100% correct, based on SNES BCD) (fixes Blazing Lazers scoring)

Many of the ones I skipped are HuC6280-originals that I don't know how to emulate just yet. I'm also really unsure about the zero page stuff. I believe we should be adding 0x2000 to the addresses to hit page 1, which is supposed to be mapped to the zero page (RAM). But when I look at turboEMU's source, I have no clue how the hell it could possibly be doing that. It looks to be reading from page 0, which is almost always ROM, which would be ... really weird. I also don't know if I've emulated the T mode opcodes correctly or not. The documentation on them is really confusing.

Update to v101r33 release. byuu says: Changelog: - PCE: HuC6280 core completed There's bound to be a countless stream of bugs, and the cycle counts are almost certainly not exact yet, but ... all instructions are implemented. So at this point, I can start comparing trace logs against Mednafen's debugger output. Of course, we're very likely to immediately slam into a wall of needing I/O registers implemented for the VDC in order to proceed further.

Update to v104r15 release. byuu says: Changelog: - processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode names with descriptive names - nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS` - icarus: added `Icarus::missing() -> string_vector` to list missing appended firmware files by name - ruby, hiro: fix macosx→macos references The processor instruction renaming was really about consistency with the other processor cores. I may still need to do this for one or two more processors. The icarus change should allow a future release of the icarus application to import games with external SNES coprocessor firmware once again. It will also allow this to be possible when used in library mode.

The icarus change should allow a future release of the icarus application to import games with external SNES coprocessor firmware once again. It will also allow this to be possible when used in library mode.

Update to v102r26 release. byuu says: Changelog: - md/ym2612: initialize DAC sample to center volume [Cydrak] - processor/arm: add accumulate mode extra cycle to mlal [Jonas Quinn] - processor/huc6280: split off algorithms, improve naming of functions - processor/mos6502: split off algorithms - processor/spc700: major revamp of entire core (~50% completed) - processor/wdc65816: fixed several bugs introduced by rewrite For the SPC700, this turns out to be very old code as well, with global object state variables, those annoying `{Boolean,Natural}BitField` types, `under_case` naming conventions, heavily abbreviated function names, etc. I'm working to get the code to be in the same design as the MOS6502, HuC6280, WDC65816 cores, since they're all extremely similar in terms of architectural design (the SPC700 is more of an off-label reimplementation of a 6502 core, but still.) The main thing left is that about 90% of the actual instructions still need to be adapted to not use the internal state (`aa`, `rd`, `dp`, `sp`, `bit` variables.) I wanted to finish this today, but ran out of time before work. I wouldn't suggest too much testing just yet. We should wait until the SPC700 core is finished for that. However, if some does want to and spots regressions, please let me know.

Update to v102r26 release. byuu says: Changelog: - md/ym2612: initialize DAC sample to center volume [Cydrak] - processor/arm: add accumulate mode extra cycle to mlal [Jonas Quinn] - processor/huc6280: split off algorithms, improve naming of functions - processor/mos6502: split off algorithms - processor/spc700: major revamp of entire core (~50% completed) - processor/wdc65816: fixed several bugs introduced by rewrite For the SPC700, this turns out to be very old code as well, with global object state variables, those annoying `{Boolean,Natural}BitField` types, `under_case` naming conventions, heavily abbreviated function names, etc. I'm working to get the code to be in the same design as the MOS6502, HuC6280, WDC65816 cores, since they're all extremely similar in terms of architectural design (the SPC700 is more of an off-label reimplementation of a 6502 core, but still.) The main thing left is that about 90% of the actual instructions still need to be adapted to not use the internal state (`aa`, `rd`, `dp`, `sp`, `bit` variables.) I wanted to finish this today, but ran out of time before work. I wouldn't suggest too much testing just yet. We should wait until the SPC700 core is finished for that. However, if some does want to and spots regressions, please let me know.

Update to v104r15 release. byuu says: Changelog: - processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode names with descriptive names - nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS` - icarus: added `Icarus::missing() -> string_vector` to list missing appended firmware files by name - ruby, hiro: fix macosx→macos references The processor instruction renaming was really about consistency with the other processor cores. I may still need to do this for one or two more processors. The icarus change should allow a future release of the icarus application to import games with external SNES coprocessor firmware once again. It will also allow this to be possible when used in library mode.

I wanted to finish this today, but ran out of time before work. I wouldn't suggest too much testing just yet. We should wait until the SPC700 core is finished for that. However, if some does want to and spots regressions, please let me know.

Update to v104r15 release. byuu says: Changelog: - processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode names with descriptive names - nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS` - icarus: added `Icarus::missing() -> string_vector` to list missing appended firmware files by name - ruby, hiro: fix macosx→macos references The processor instruction renaming was really about consistency with the other processor cores. I may still need to do this for one or two more processors. The icarus change should allow a future release of the icarus application to import games with external SNES coprocessor firmware once again. It will also allow this to be possible when used in library mode.

The main thing left is that about 90% of the actual instructions still need to be adapted to not use the internal state (`aa`, `rd`, `dp`, `sp`, `bit` variables.) I wanted to finish this today, but ran out of time before work. I wouldn't suggest too much testing just yet. We should wait until the SPC700 core is finished for that. However, if some does want to and spots regressions, please let me know.

Update to v104r15 release. byuu says: Changelog: - processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode names with descriptive names - nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS` - icarus: added `Icarus::missing() -> string_vector` to list missing appended firmware files by name - ruby, hiro: fix macosx→macos references The processor instruction renaming was really about consistency with the other processor cores. I may still need to do this for one or two more processors. The icarus change should allow a future release of the icarus application to import games with external SNES coprocessor firmware once again. It will also allow this to be possible when used in library mode.

Update to v101r33 release. byuu says: Changelog: - PCE: HuC6280 core completed There's bound to be a countless stream of bugs, and the cycle counts are almost certainly not exact yet, but ... all instructions are implemented. So at this point, I can start comparing trace logs against Mednafen's debugger output. Of course, we're very likely to immediately slam into a wall of needing I/O registers implemented for the VDC in order to proceed further.

Many of the ones I skipped are HuC6280-originals that I don't know how to emulate just yet. I'm also really unsure about the zero page stuff. I believe we should be adding 0x2000 to the addresses to hit page 1, which is supposed to be mapped to the zero page (RAM). But when I look at turboEMU's source, I have no clue how the hell it could possibly be doing that. It looks to be reading from page 0, which is almost always ROM, which would be ... really weird. I also don't know if I've emulated the T mode opcodes correctly or not. The documentation on them is really confusing.
