Reesy has updated the Snes emulator for the GP32, heres what he says:
Hi,
I've been messing around with OpenSnes by Yoyofr, I finally got it to compile using ADS and I have added some more cpu speeds to it. This build is not using the asm cpu core as it is not in a ADS compatible format so I'm going to need to convert it over the next few days. Once I've done this I may have a go at adding a faster spc emulator to it ( pocketspc ). If you plan on compiling this you'll need to use the Debug release of Gamepark SDK for ADS as the release version is broken.
Later
