Update to v094r31 release. byuu says: This WIP scores 448/920 tests passed. Gave a shot at ROM prefetch that failed miserably (ranged from 409 to 494 tests passed. Nowhere near where it would be if it were implemented correctly.) Three remaining issues: - ROM prefetch - DMA timing - timers (I suspect it's a 3-clock delay in starting, not a 3-clock into the future affair) Probably only going to be able to get the timers working without heroic amounts of effort. MUL timing is fixed to use idle cycles. STMIA is fixed to set sequential at the right moments. DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer. In other news ... I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those Window_configure issues go away. I realize I was leaking Display* handles in the X-video driver while I was looking at it, so I fixed those. I added DT_NOPREFIX so the Windows ListView will show & characters correctly now.

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.)

auto CPU::dma_exec(Registers::DMA& dma) -> void {
Update to v095r07 release. byuu says: Changelog: - entire GBA core ported to auto function() -> return; syntax - fixed GBA BLDY bug that was causing flickering in a few games - replaced nall/config usage with nall/string/markup/node - this merges all configuration files to a unified settings.bml file - added "Ignore Manifests" option to the advanced setting tab - this lets you keep a manifest.bml for an older version of higan; if you want to do regression testing Be sure to remap your controller/hotkey inputs, and for SNES, choose "Gamepad" from "Controller Port 1" in the system menu. Otherwise you won't get any input. No need to blow away your old config files, unless you want to.

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 v095r03 release and icarus 20151107. byuu says: Note: you will need the new icarus (and please use the "no manifest" system) to run GBA games with this WIP. Changelog: - fixed caching of r(d) to pass armwrestler tests [Jonas Quinn] - DMA to/from GBA BIOS should fail [Cydrak] - fixed sign-extend and rotate on ldrs instructions [Cydrak] - fixed 8-bit SRAM reading/writing [byuu] - refactored GBA/cartridge - cartridge/rom,ram.type is now cartridge/mrom,sram,eeprom,flash - things won't crash horribly if you specify a RAM size larger than the largest legal size in the manifest - specialized MROM / SRAM classes replace all the shared read/write functions that didn't work right anyway - there's a new ruby/video.glx2 driver, which is not enabled by default - use this if you are running Linux/BSD, but don't have OpenGL 3.2 yet - I'm not going to support OpenGL2 on Windows/OS X, because these OSes don't ship ancient video card drivers - probably more. What am I, clairvoyant? :P For endrift's tests, this gets us to 1348/1552 memory and 1016/1260 timing. Overall, this puts us back in second place. Only no$ is ahead on memory, but bgba is even more ahead on timing.

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.

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.

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 v094r31 release. byuu says: This WIP scores 448/920 tests passed. Gave a shot at ROM prefetch that failed miserably (ranged from 409 to 494 tests passed. Nowhere near where it would be if it were implemented correctly.) Three remaining issues: - ROM prefetch - DMA timing - timers (I suspect it's a 3-clock delay in starting, not a 3-clock into the future affair) Probably only going to be able to get the timers working without heroic amounts of effort. MUL timing is fixed to use idle cycles. STMIA is fixed to set sequential at the right moments. DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer. In other news ... I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those Window_configure issues go away. I realize I was leaking Display* handles in the X-video driver while I was looking at it, so I fixed those. I added DT_NOPREFIX so the Windows ListView will show & characters correctly now.

auto CPU::dma_vblank() -> void {
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.
