Many of the developers have been working on MeeGo for months now, they have in a few posts here and there pointed out that the coding for MeeGo will allow for if not native, at least easy porting to Maemo 5.

Or you can convert the device to MeeGo when the public option becomes available. Some emulators have classically had issue's being brought to the mobile platforms BTW [PDA's, Phones etc ...]. DS, PS1 and PSP emulators being the big ones. They require a lot from the host systems to emulate.

I remember fiddling with pcsx on my pocket pc [iMate JasJar] and being more or less underwhelmed. Love the NES, SNES and GBA emulators though good work on them.
