ok, i'm trying to make a gba that's complete with all the megaman classics made for the gb mono. some of the games actually work but some will display a blank screen. i'm wondering if the goomba's able to use sgb files, too. what is an sgb file, anyway? i only remember gb files, back then. i renamed the sgb file to gb and it worked but i'm still not sure if that was right. honestly, i'd really like to see the release of "megaman anniversary collection / mania". i was on a gaming site and it said the game was cancelled. really sad to see that.
