@padre unfortunately, the ppsspp core isnt likely to make it to 360. It would require writing a new PPC dynarec to get full speed and even then it would be doubtful.
EDIT: nvm, they just merged a PPC dynarec upstream, apparently, so a 360 port is planned, though it won’t be in the next 1.1 release. Possibly 1.2 or whatever, though.
