Squidge let us know he has released a new version of his SNES emulator for the GP2X.
I've changed the graphics routines on this one, and it seems to be a fair amount quicker. The main problem was trying to sync with the LCD refresh - why oh why can't we just use a vsync interrupt?
The proper way to exit is to hold down SELECT for at least 2 seconds, as I've said previously, but some people may not have read the entire thread. This version also has a frame rate limiter built in, so games shouldn't run too fast. It uses rlyeh's timer routines for this however, so I've no idea if they handle overclocking.
Next version will have command line support, and possibly a menu
