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.

auto PPU::read(uint32 addr) -> uint8 {
Update to v087r14 release. byuu says: Fixed aforementioned issues. [From a previous post: - mul was using r(d) instead of r(n) for accumulate. - mull didn't remove c/v clear. - APU register mask was broken, so SOUNDBIAS was reading out wrong. - APU was only mapping 0x088 and not 0x089 as well. - Halfword reads in CPU+PPU+APU were all reading from the low address each time.] All CPU+PPU registers are now hooked up (not that they do anything.) SOUNDBIAS for APU was hooked up, got tired of working on it for the rest :P I recall from the GB APU that you can't just assign values for the APU MMIO regs. They do odd reload things as well. Also, was using MMIO read code like this: return ( (flaga << 0) || (flagb << 1) || (flagc << 2) ); Logical or doesn't work so well with building flags :P Bad habit from how I split multiple conditionals across several lines. So ... r14 is basically what r13 should have been yesterday, delaying my schedule by yet another day :(

Update to v087r12 release. byuu says: Enough to get through the BIOS and into cartridge ROM. I am a bit annoyed that I was basically told that the GBA PPU wasn't that bad. Sprites are a clusterfuck, easily worse than Mode7, docs don't even begin to explain them in enough detail. This is going to be fun.

Update to v087r13 release. byuu says: Contains all of Cydrak's fixes, sans PPU. On the PPU front, I've hooked up 100% of read and write registers. All three DISPSTAT IRQs (Vblank, Hblank, Vcoincidence) are connected now as well. Super Mario Advance now runs without *appearing* to crash, although it's hard to tell since I have no video or sound :P ARM Wrestler is known to run, as is the BIOS.

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 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 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.

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.

Haven't converted all unsigned->uint yet. Also, probably won't do sfc/alt as that's mostly just speed hack stuff.

SOUNDBIAS for APU was hooked up, got tired of working on it for the rest :P I recall from the GB APU that you can't just assign values for the APU MMIO regs. They do odd reload things as well. Also, was using MMIO read code like this: return ( (flaga << 0) || (flagb << 1) || (flagc << 2) ); Logical or doesn't work so well with building flags :P Bad habit from how I split multiple conditionals across several lines. So ... r14 is basically what r13 should have been yesterday, delaying my schedule by yet another day :(

Update to v087r12 release. byuu says: Enough to get through the BIOS and into cartridge ROM. I am a bit annoyed that I was basically told that the GBA PPU wasn't that bad. Sprites are a clusterfuck, easily worse than Mode7, docs don't even begin to explain them in enough detail. This is going to be fun.

Update to v087r22 release. byuu says: Changelog: - fixed below pixel green channel on color blending - added semi-transparent objects [Exophase's method] - added full support for windows (both inputs, OBJ windows, and output, with optional color effect disable) - EEPROM uses nall::bitarray now to be friendlier to saving memory to disk - removed incomplete mosaic support for now (too broken, untested) - improved sprite priority. Hopefully it's right now. Just about everything should look great now. It took 25 days, but we finally have the BIOS rendering correctly. In order to do OBJ windows, I had to drop my above/below buffers entirely. I went with the nuclear option. There's separate layers for all BGs and objects. I build the OBJ window table during object rendering. So as a result, after rendering I go back and apply windows (and the object window that now exists.) After that, I have to do a painful Z-buffer select of the top two most important pixels. Since I now know the layers, the blending enable tests are a lot nicer, at least. But this obviously has quite a speed hit: 390fps to 325fps for Mr. Driller 2 title screen. TONC says that "bad" window coordinates do really insane things. GBAtek says it's a simple y2 < y1 || y2 > 160 ? 160 : y2; x2 < x1 || x2 > 240 ? 240 : x2; I like the GBAtek version more, so I went with that. I sure hope it's right ... but my guess is the hardware does this with a counter that wraps around or something. Also, say you have two OBJ mode 2 sprites that overlap each other, but with different priorities. The lower (more important) priority sprite has a clear pixel, but the higher priority sprite has a set pixel. Do we set the "inside OBJ window" flag to true here? Eg does the value OR, or does it hold the most important sprite's pixel value? Cydrak suspects it's OR-based, I concur from what I can see. Mosaic, I am at a loss. I really need a lot more information in order to implement it. For backgrounds, does it apply to the Vcounter of the entire screen? Or does it apply post-scroll? Or does it even apply after every adjust in affine/bitmap modes? I'm betting the hcounter background mosaic starts at the leftmost edge of the screen, and repeats previous pixels to apply the effect. Like SNES, very simple. For sprites, the SNES didn't have this. Does the mosaic grid start at (0,0) of the screen, or at (0,0) of each sprite? The latter will look a lot nicer, but be a lot more complex. Is mosaic on affine objects any different than mosaic of linear(tiled) objects? With that out of the way, we still have to fix the CPU memory access timing, add the rest of the CPU penalty cycles, the memory rotation / alignment / extend behavior needs to be fixed, the shifter desperately needs to be moved from loops to single shift operations, and I need to add flash memory support.

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 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 v087r13 release. byuu says: Contains all of Cydrak's fixes, sans PPU. On the PPU front, I've hooked up 100% of read and write registers. All three DISPSTAT IRQs (Vblank, Hblank, Vcoincidence) are connected now as well. Super Mario Advance now runs without *appearing* to crash, although it's hard to tell since I have no video or sound :P ARM Wrestler is known to run, as is the BIOS.

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 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 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& bg = regs.bg[(addr >> 4) & 3];
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 v087r13 release. byuu says: Contains all of Cydrak's fixes, sans PPU. On the PPU front, I've hooked up 100% of read and write registers. All three DISPSTAT IRQs (Vblank, Hblank, Vcoincidence) are connected now as well. Super Mario Advance now runs without *appearing* to crash, although it's hard to tell since I have no video or sound :P ARM Wrestler is known to run, as is the BIOS.
