Update to v098r02 release. byuu says: Changelog: - SFC: fixed a regression on auto joypad polling due to missing parentheses - SFC: exported new PPU::vdisp() const -> uint; function [1] - SFC: merged PPU MMIO functions into the read/write handles (as I previously did for the CPU) - higan: removed individual emulator core names (bnes, bsnes, bgb, bgba, bws) [2] Forgot: - to remove /tomoko from the about dialog [1] note that technically I was relying on the cached, per-frame overscan setting when the CPU and light guns were polling the number of active display scanlines per frame. This was technically incorrect as you can change this value mid-frame and it'll kick in. I've never seen any game toggle overscan every frame, we only know about this because anomie tested this a long time ago. So, nothing should break, but ... you know how the SNES is. You can't even look at the code without something breaking, so I figured I'd mention it >_> [2] I'll probably keep referring to the SNES core as bsnes anyway. I don't mind if you guys use the b<system> names as shorthand. The simplification is mostly to make the branding easier.

Update to 20100809 release. byuu says: This adds some sync.sh improvements to make it handle errors more gracefully. It also updates asnes a good bit. All of the four base processors now have all publicly accessible functions right at the top of the main headers, and everything else is private. This is to allow these headers to essentially take the place of the previous base classes in the old bsnes-merged format. So if there's something public there, you need to implement that exact function to make your own module. I removed the frame counter from the PPU, as it has nothing to do with emulation. That now resides inside the Qt -> SNES interface code. Quite amazing, I was actually saving the frame counter into the save state files before, yuck. Removed some baggage in the System class: it was friending a bunch of long-dead functions and classes. Forgot to re-add the CHEAT_SYSTEM define to info.hpp, so that's been put back.

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.

static auto Enter() -> void;
Update to v097r13 release. byuu says: I refactored my schedulers. Added about ten lines to each scheduler, and removed about 100 lines of calling into internal state in the scheduler for the FC,SFC cores and about 30-40 lines for the other cores. All of its state is now private. Also reworked all of the entry points to static auto Enter() and auto main(). Where Enter() handles all the synchronization stuff, and main() doesn't need the while(true); loop forcing another layer of indentation everywhere. Took a few hours to do, but totally worth it. I'm surprised I didn't do this sooner. Also updated icarus gmake install rule to copy over the database.

Update to v085r06 release. byuu says: Lots of debugger enhancements. Memory editor works for CPU-bus only, breakpoint editor does nothing yet. Tracing works, writes to 001-999 files sequentially. Stepping works, too. But only on the CPU. Added "privileged", which becomes "public" if DEBUGGER is defined, "private" otherwise. Meant so the debugger can stab deeply into the cores for state manipulation. Interface is guaranteed to be unstable and dependent upon the accuracy core. The about screen logo adds 100KB onto the source download (won't affect regular bsnes binaries), but too bad. I want some visual flair this time.

Update to v093r02 release. byuu says: Changelog: - nall: fixed major memory leak in string class - ruby: video shaders support #define-based settings now - phoenix/GTK+: support > 256x256 icons for window / task bar / alt-tab - sfc: remove random/ and config/, merge into system/ - ethos: delete higan.png (48x48), replace with higan512.png (512x512) as new higan.png - ethos: default gamma to 100% (no color adjustment) - ethos: use "Video Shaders/Display Emulation/" instead of "Video Shaders/Emulation/" - use g++ instead of g++-4.7 (g++ -v must be >= 4.7) - use -std=c++11 instead of -std=gnu++11 - applied a few patches from Debian upstream to make their packaging job easier So because colors are normalized in GLSL, I won't be able to offer video shaders absolute color literals. We will have to perform basic color conversion inside the core. As such, the current plan is to create some sort of Emulator::Settings interface. With that, I'll connect an option for color correction, which will be on by default. For FC/SFC, that will mean gamma correction (darker / stronger colors), and for GB/GBC/GBA, it will mean simulating the weird brightness levels of the displays. I am undecided on whether to use pea soup green for the GB or not. By not doing so, it'll be easier for the display emulation shader to do it.

uint32* output = nullptr;
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?

Note: there seems to be some kind of added audio lag in the SGB emulation now, and I don't really understand why. The code should be effectively identical to what I had before. The only main thing is that I'm sampling things to 48000hz instead of 32040hz before mixing. There's no point where I'm intentionally introducing added latency though. I'm kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be much appreciated :/ I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as well, and that would be very bad.

Still some unknown areas in there, but hopefully it's enough to get further into games that depend on EEPROM support. Note that you'll have to manually add the eeprom line to the manifest for now, as icarus doesn't know how to detect EEPROM/sizes yet. I figured the changes to the SNES PPU sprites would slow it down a tad, but it actually sped it up. Most of the impact from the integer classes are gone now.

Update to v085r06 release. byuu says: Lots of debugger enhancements. Memory editor works for CPU-bus only, breakpoint editor does nothing yet. Tracing works, writes to 001-999 files sequentially. Stepping works, too. But only on the CPU. Added "privileged", which becomes "public" if DEBUGGER is defined, "private" otherwise. Meant so the debugger can stab deeply into the cores for state manipulation. Interface is guaranteed to be unstable and dependent upon the accuracy core. The about screen logo adds 100KB onto the source download (won't affect regular bsnes binaries), but too bad. I want some visual flair this time.

Update to v085r03 release. byuu says: Changelog: - fixed cursor being visible under Metacity window manager (hopefully doesn't cause regression with other WMs) - show normal cursor when using SDL video driver - added menu accelerators (meh, why not?) - removed debugvirtual, ChipDebugger and chip/debugger functionality entirely - alt/smp disassembler moved up - fixed alt/smp incw/decw instructions (unsigned->uint16 for internal variables) My plan going forward for a debugger is not to hardcode functionality that causes the 10-15% slowdown right into the emulator itself. Instead, I'm going to make a callback class, which will be a specialized version of nall::function: - can call function even if not assigned (results in no-op, return type must have a trivial default constructor) - if compiled without #define DEBUGGER, the entire thing turns into a huge no-op; and will be eliminated entirely when compiled - strategically place the functions: cb_step, cb_read, cb_write, etc. From here, the ui-debugger GUI will bind the callbacks, implement breakpoint checking, usage table generation, etc itself. I'll probably have to add some breakout commands to exit the emulation core prior to a frame event in some cases as well. I didn't initially want any debugger-related stuff in the base cores, but the #if debugger sCPUDebugger #else sCPU #endif stuff was already more of a burden than this will be.
