Wow, that's a surprise. First FakeNES, and now this. The homepage says to stop distributing RBA, so maybe that means that legal issues were involved (like multiplayer)?
Mmh.. we don't have so many good GBA emus and now one more is gone...
And he hasn't released the source, that's a shame...
But I don't think that's a nintendo thing! Come on, how will BigN do this?
