Okay, I'll post this issue here since reporting it to google code is pointless. This is a very peculiar, yet very noticeable glitch in Snes9xGx 4.2.6 and on, where SA-1 games are affected. Now, the version I am using, 4.2.8, had the IRQ changes reverted, since that was detrimental to the framerate, but something is still amiss. Steps to reproduce emulator bug: 1 - Load Snes9xGx Wii 2 - Open up Kirby's Dreamland 3 3 - Start moving so the screen can scroll left or right 4 - Horizontal/Vertical scrolling should be constant 60fps, but it's somewhere in the range of 50-55fps. Now, I have the Virtual Console version as well and I wanted to compare running it on Snes9xGx Wii and the VC. Oddly enough, the VC version has full speed during vertical/horizontal scrolling, but Snes9xGx does not. They're both being emulated, I know that, but seriously, this is perplexing. Video showing how it should be - http://www.mediafire...itlc89ie9xn92q1 Think of Snes9xGx changing frameskip up and down, making it choppy versus being smooth. Surely, if the VC version can do it, then Snes9xGx should be able to do so as well. It can't be the Wii's fault, can it? To sum up: Why does Snes9xGx run Kirby's Dreamland 3 at a choppier framerate than the Virtual Console version? Isn't there ANYTHING that could be done to optimize it? Or is this because I'm running off an SD card? Information - Version: 4.2.8 official ( http://tinyurl.com/3nclvar ) Wii System Menu: 4.3 U/NTSC Snes9xGx Forwarder: http://tinyurl.com/3gjvsp5 HBC Version: 1.0.8 Tried both boot.dol and boot.elf files. ROM: Kirby's Dreamland 3 (U) [!].sfc Checksum: Okay ROM Size: 32mbit Region: NTSC-U Heck, other games (like Final Fantasy VI) are affected as well (framerate dips). Why VC games don't experience the same slowdowns as Snes9xGx is beyond me.
