Updated to v067r21 release. byuu says: This moves toward a profile-selection mode. Right now, it is incomplete. There are three binaries, one for each profile. The GUI selection doesn't actually do anything yet. There will be a launcher in a future release that loads each profile's respective binary. I reverted away from blargg's SMP library for the time being, in favor of my own. This will fix most of the csnes/bsnes-performance bugs. This causes a 10% speed hit on 64-bit platforms, and a 15% speed hit on 32-bit platforms. I hope to be able to regain that speed in the future, I may also experiment with creating my own fast-SMP core which drops bus hold delays and TEST register support (never used by anything, ever.) Save states now work in all three cores, but they are not cross-compatible. The profile name is stored in the description field of the save states, and it won't load a state if the profile name doesn't match. The debugger only works on the research target for now. Give it time and it will return for the other targets. Other than that, let's please resume testing on all three once again. See how far we get this time :) I can confirm the following games have issues on the performance profile: - Armored Police Metal Jacket (minor logo flickering, not a big deal) - Chou Aniki (won't start, so obviously unplayable) - Robocop vs The Terminator (major in-game flickering, unplayable) Anyone still have that gigantic bsnes thread archive from the ZSNES forum? Maybe I posted about how to fix those two broken games in there, heh. I really want to release this as v1.0, but my better judgment says we need to give it another week. Damn.

Updated to v067r23 release. byuu says: Added missing $4200 IRQ lock, which fixes Chou Aniki on the fast CPU core, so slower PCs can get their brotherly love on. Added range-based controller IOBit latching to the fast CPU core, which enables Super Scope and Justifier support. Uses the priority queue as well, so there is zero speed-hit. Given the way range-testing works, the trigger point may vary by 1-2 pixels when firing at the same spot. Not really a big deal when it avoids a massive speed penalty. Fixed PAL and interlace-mode HVIRQs at V=0,H<2 on the fast CPU core. Added the dot-renderer's sprite list update-on-OAM-write functionality to the scanline-based PPU renderer. Unfortunately it looks like all the speed gain was already taken from the global dirty flag I was using before, but this certainly won't hurt speed any, so whatever. Added #ifdef to stop CoInitialize(0) on non-Windows ports. Added #ifdefs to stop gradient fade on Windows port. Not going to fuck over the Linux port aesthetic because of Qt bug #47,326,927. If there's a way to tell what Qt theme is being used, I can leave it enabled for XP/Vista themes. Moved HDMA trigger from 1104 to 1112, and reduced channel overhead from 24 to 16, to better simulate one-cycle DMA->CPU sync. Code clarity: I've re-added my varint.hpp classes, and am actively using them in the accuracy cores. So far, I haven't done anything that would detriment speed, but it is certainly cool. The APU ports exposed by the CPU and SMP now take uint2 address arguments, the CPU WRAM address register is a uint17, and the IRQ H/VTIME values are uint10. This basically allows the source to clearly convey the data sizes, and eliminates the need to manually mask values when writing to registers or reading from memory. I'm going to be doing this everywhere, and it will have a speed impact eventually, because the automation means we can't skip masks when we know the data is already masked off. Source: archive contains the launcher code, so that I can look into why it's crashing on XP tomorrow. It doesn't look like Circuit USA's flags are going to work too well with this new CPU core. Still not sure what the hell Robocop vs The Terminator is doing, I'll read through the mega SNES thread for clues tomorrow. Speedy Gonzales is definitely broken, as modifying the MDR was breaking things with my current core. Probably because the new CPU core doesn't wait for a cycle edge to trigger. I was thinking that perhaps we could keep some form of cheat codes list to work as game-specific hacks for the performance core. Keeps the hacks out of the emulator, but could allow the remaining bugs to be worked around for people who have no choice but to use the performance core.
