Haha, are you kidding? I can make an exhausting long list of awesome games for the GBA. Among them are Final Fantasy VI (the newer, better localized edition) and lots of awesome Mario games. Also the Sonic Advanced series and a lot of stuff I've probably forgotten about. There are a slew of great RPGs that are perfect for the N900. It shouldn't be too hard to emulate, my old 6120C with a 300mhz CPU handled it just fine. Better than VGBA that's for sure.
