I am beta testing the Sony version. As far as the GB/GBC cores are concerened the emulation is almost perfect and in most cases, seems to be a little too fast. The GBA portion hasn't been implemented yet, so I can't comment on that yet.
Originally posted by Mas how large is the screen on a standard clamshell clie like mine or the nx70 series? from the screen shot of the zodiac..the emulated screen looks even smaller than the NesEm !!!
It can be viewd in it's native resolution or it can be scaled to fit the entire screen. Both modes look real good. The "stretched" mode doesn't look awkward either.
