Quickly tries several games...
Overall it's a HUGe improvement, bringing SNES emulation into the realm of real playability for GP32.
In most games, with sound OFF, you can get good speeds with 3 - 5 frame skips. How many frames per second is that exactly? Not sure how the increments are setup. But skip 3 seems fairly smooth.
With sound ON, you have to use MANY frameskips for good speed, maybe around 6 - 8, or more. And on many games you simply can't really play them with sound - way too choppy.
RPG's are very nice with sound on tho, since smooth scrolling isn't so important. But the sound tends to click and crack quite a bit unfortunately.
SRAM support and kep mapping work well too.
Superb step forward for SNES emus on GP32. Can it get much better? If so, we're in for a major treat someday. If not, well, this is much better than what we had previously.
