I have installed the debs and tested, really it can play .psf(Sony Playstation) .dsf(Sega Dreamcast) .ssf(Sega Saturn) .psf2f(Sony Playstation2) as 0.4.2 changelog listed. but as we thought, it plays slow and cutdown, even non closable some while.

Can anyone fix and update it? make support .gsf(Gameboy Advance) .usf(Nintendo64) .2sf(Nintendo DS) as IOS does?or even 7z files?

Perhaps our N900 is NOT as strong as we expect?
