Ok after installing several wads (N64,SNES,NES) most are working, however there are a few that do not run and just give me a black screen. Notably: N64 - Kirby and the crystal shards SNES - Super Mario RPG Im pretty sure I have the US version of the games, not PAL. Should updating my IOS fix this? Such as d2x? I'm not sure what the problem is..
