Update to v087r16 release. byuu says: Fixed the r15 mask per Cydrak. Added DMA support (immediate + Vblank + Hblank + HDMA) with IRQ support. Basically only missing FIFO reload mode for the APU on channel 2. Added background linear renderer (tilemap mode.) Added really inefficient pixel priority selector, so that all BGs+OBJ could be visible onscreen at the same time. As a result of the above: * Mr. Driller is our first fully playable game * Bakunetsu Dodge Ball Fighters is also fully playable * Pinobee no Daibouken is also fully playable Most games (15 of 16 tested) are now showing *something*, many things look really really good in fact. Absolutely essential missing components: - APU - CPU timers and their interrupts - DMA FIFO mode - OBJ affine mode - BG affine mode - BG bitmap mode - PPU windows (BG and OBJ) - PPU mosaic - PPU blending modes - SRAM / EEPROM (going to rely on a database, not heuristics. Homebrew will require a manifest file.)

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.

Update to v087r30 release. byuu says: Changelog: - DMA channel masks added (some are 27-bit source/target and some are 14-bit length -- hooray, varuint_t class.) - No more state.pending flags. Instead, we set dma.pending flag when we want a transfer (fixes GBA Video - Pokemon audio) [Cydrak] - fixed OBJ Vmosaic [Cydrak, krom] - OBJ cannot read <=0x13fff in BG modes 3-5 (fixes the garbled tile at the top-left of some games) - DMA timing should be much closer to hardware now, but probably not perfect - PPU frame blending uses blargg's bit-perfect, rounded method (slower, but what can you do?) - GBA carts really unload now - added nall/gba/cartridge.hpp: used when there is no manifest. Scans ROMs for library tags, and selects the first valid one found - added EEPROM auto-detection when EEPROM size=0. Forces disk/save state size to 8192 (otherwise states could crash between pre and post detect.) - detects first read after a set read address command when the size is zero, and sets all subsequent bit-lengths to that value, prints detected size to terminal - added nall/nes/cartridge.hpp: moves iNES detection out of emulation core. Important to note: long-term goal is to remove all nall/(system)/cartridge.hpp detections from the core and replace with databases. All in good time. Anyway, the GBA workarounds should work for ~98.5% of the library, if my pre-scanning was correct (~40 games with odd tags. I reject ones without numeric versions now, too.) I think we're basically at a point where we can release a new version now. Compatibility should be relatively high (at least for a first release), and fixes are only going to affect one or two games at a time. I'd like to start doing some major cleaning house internally (rename NES->Famicom, SNES->SuperFamicom and such.) Would be much wiser to do that on a .01 WIP to minimize regressions. The main problems with a release now: - speed is pretty bad, haven't really optimized much yet (not sure how much we can improve it yet, this usually isn't easy) - sound isn't -great-, but the GBA audio sucks anyway :P - couple of known bugs (Sonic X video, etc.)

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 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.

As a result of the above: * Mr. Driller is our first fully playable game * Bakunetsu Dodge Ball Fighters is also fully playable * Pinobee no Daibouken is also fully playable Most games (15 of 16 tested) are now showing *something*, many things look really really good in fact. Absolutely essential missing components: - APU - CPU timers and their interrupts - DMA FIFO mode - OBJ affine mode - BG affine mode - BG bitmap mode - PPU windows (BG and OBJ) - PPU mosaic - PPU blending modes - SRAM / EEPROM (going to rely on a database, not heuristics. Homebrew will require a manifest file.)

Update to v087r30 release. byuu says: Changelog: - DMA channel masks added (some are 27-bit source/target and some are 14-bit length -- hooray, varuint_t class.) - No more state.pending flags. Instead, we set dma.pending flag when we want a transfer (fixes GBA Video - Pokemon audio) [Cydrak] - fixed OBJ Vmosaic [Cydrak, krom] - OBJ cannot read <=0x13fff in BG modes 3-5 (fixes the garbled tile at the top-left of some games) - DMA timing should be much closer to hardware now, but probably not perfect - PPU frame blending uses blargg's bit-perfect, rounded method (slower, but what can you do?) - GBA carts really unload now - added nall/gba/cartridge.hpp: used when there is no manifest. Scans ROMs for library tags, and selects the first valid one found - added EEPROM auto-detection when EEPROM size=0. Forces disk/save state size to 8192 (otherwise states could crash between pre and post detect.) - detects first read after a set read address command when the size is zero, and sets all subsequent bit-lengths to that value, prints detected size to terminal - added nall/nes/cartridge.hpp: moves iNES detection out of emulation core. Important to note: long-term goal is to remove all nall/(system)/cartridge.hpp detections from the core and replace with databases. All in good time. Anyway, the GBA workarounds should work for ~98.5% of the library, if my pre-scanning was correct (~40 games with odd tags. I reject ones without numeric versions now, too.) I think we're basically at a point where we can release a new version now. Compatibility should be relatively high (at least for a first release), and fixes are only going to affect one or two games at a time. I'd like to start doing some major cleaning house internally (rename NES->Famicom, SNES->SuperFamicom and such.) Would be much wiser to do that on a .01 WIP to minimize regressions. The main problems with a release now: - speed is pretty bad, haven't really optimized much yet (not sure how much we can improve it yet, this usually isn't easy) - sound isn't -great-, but the GBA audio sucks anyway :P - couple of known bugs (Sonic X video, etc.)

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.
