I haven't tried it (haven't got a flash cart), but from what i heard from a couple friends, it's legit. I'm not sure how old this is (was released this year it seems), but i haven't seen it posted before and i just now found it. Seems interesting, though i doubt it'll get to any kind of substantial playability.

It'll probably be at most half speed.

it IS legit and IS real, cept its reaaaaal buggy and only game it would boot (that i have) is Super Mario World, btw, you don't need a flash cart as all X to GBA emus do is pack the rom along with the emu into a GBA rom, so all you really need is VBA or BoycottAdvance

Yeah, its real, its also slow, and buggy, but hot damn if it isnt progress, plus, the guy working on it is the same guy who did PocketNES, you may or may not know him as Loopy, (name not state of mind) I know he hangs around the GBATemp forums. It's a hell of a thing seeing SNES games emulated on a GBA.

There are over 30 Games confirmed to be playable with this Emu.

And the Purpose of this emu is to play the SNES games on the go with the GBA, and not on a Emulator like VBA.
