Update to v098r12 release. byuu says: Changelog: - higan/video: added support for Emulator::Sprite - higan/resource: a new system for accessing embedded binary files inside the emulation cores; holds the sprites - higan/sfc/superscope,justifier: re-enabled display of crosshairs - higan/sfc/superscope: fixed turbo toggle (also shows different crosshair color when in turbo mode) - higan/sfc/ppu: always outputs at 512x480 resolution now - causes a slight speed-hit from ~127fps to ~125fps; - but allows high-resolution 32x32 cursors that look way better; - also avoids the need to implement sprite scaling logic Right now, the PPU code to always output at 480-height is a really gross hack. Don't worry, I'll make that nicer before release. Also, superscope.cpp and justifier.cpp are built around a 256x240 screen. But since we now have 512x480, we can make the cursor's movement much smoother by doubling the resolution on both axes. The actual games won't see any accuracy improvements when firing the light guns, but the cursors will animate nicer so I think it's still worth it. I'll work on that before the next release as well. The current 32x32 cursors are nicer, but we can do better now with full 24-bit color. So feel free to submit alternatives. I'll probably reject them, but you can always try :D The sprites don't support alpha blending, just color keying (0x00000000 = transparent; anything else is 0xff......). We can revisit that later if necessary. The way I have it designed, the only files that do anything with Emulator::Sprite at all are the superscope and justifier folders. I didn't have to add any hooks anywhere else. Rendering the sprite is a lot cleaner than the old code, too.

Update to v100r14 release. byuu says: (Windows: compile with -fpermissive to silence an annoying error. I'll fix it in the next WIP.) I completely replaced the time management system in higan and overhauled the scheduler. Before, processor threads would have "int64 clock"; and there would be a 1:1 relationship between two threads. When thread A ran for X cycles, it'd subtract X * B.Frequency from clock; and when thread B ran for Y cycles, it'd add Y * A.Frequency from clock. This worked well and allowed perfect precision; but it doesn't work when you have more complicated relationships: eg the 68K can sync to the Z80 and PSG; the Z80 to the 68K and PSG; so the PSG needs two counters. The new system instead uses a "uint64 clock" variable that represents time in attoseconds. Every time the scheduler exits, it subtracts the smallest clock count from all threads, to prevent an overflow scenario. The only real downside is that rounding errors mean that roughly every 20 minutes, we have a rounding error of one clock cycle (one 20,000,000th of a second.) However, this only applies to systems with multiple oscillators, like the SNES. And when you're in that situation ... there's no such thing as a perfect oscillator anyway. A real SNES will be thousands of times less out of spec than 1hz per 20 minutes. The advantages are pretty immense. First, we obviously can now support more complex relationships between threads. Second, we can build a much more abstracted scheduler. All of libco is now abstracted away completely, which may permit a state-machine / coroutine version of Thread in the future. We've basically gone from this: auto SMP::step(uint clocks) -> void { clock += clocks * (uint64)cpu.frequency; dsp.clock -= clocks; if(dsp.clock < 0 && !scheduler.synchronizing()) co_switch(dsp.thread); if(clock >= 0 && !scheduler.synchronizing()) co_switch(cpu.thread); } To this: auto SMP::step(uint clocks) -> void { Thread::step(clocks); synchronize(dsp); synchronize(cpu); } As you can see, we don't have to do multiple clock adjustments anymore. This is a huge win for the SNES CPU that had to update the SMP, DSP, all peripherals and all coprocessors. Likewise, we don't have to synchronize all coprocessors when one runs, now we can just synchronize the active one to the CPU. Third, when changing the frequencies of threads (think SGB speed setting modes, GBC double-speed mode, etc), it no longer causes the "int64 clock" value to be erroneous. Fourth, this results in a fairly decent speedup, mostly across the board. Aside from the GBA being mostly a wash (for unknown reasons), it's about an 8% - 12% speedup in every other emulation core. Now, all of this said ... this was an unbelievably massive change, so ... you know what that means >_> If anyone can help test all types of SNES coprocessors, and some other system games, it'd be appreciated. ---- Lastly, we have a bitchin' new about screen. It unfortunately adds ~200KiB onto the binary size, because the PNG->C++ header file transformation doesn't compress very well, and I want to keep the original resource files in with the higan archive. I might try some things to work around this file size increase in the future, but for now ... yeah, slightly larger archive sizes, sorry. The logo's a bit busted on Windows (the Label control's background transparency and alignment settings aren't working), but works well on GTK. I'll have to fix Windows before the next official release. For now, look on my Twitter feed if you want to see what it's supposed to look like. ---- EDIT: forgot about ICD2::Enter. It's doing some weird inverse run-to-save thing that I need to implement support for somehow. So, save states on the SGB core probably won't work with this WIP.
