When I load the FAT rom from akmenu4.nds, I get a black screen on top and bottom. If I load it normally from my games folder, I get a Guru Meditation error. I use an R4i.
if they get permission from 4j (the studio who helped put minecraft on consoles), they could put the console edition tutorial worlds in the game, as seeds
and i mean all of them (if not, maybe a few highlights, like TU1, TU31, and TU69)
