Version 1.2 ADF was where I saw it. I did see someone on EAB having the same issue too. Happy to send you a save state if that helps with debugging. I basically get 3 or 4 frames of the first SMB level before it goes black, maybe before Pix spawns?
You're correct, the game gets black in first SMB level. I've just arranged this. You can try now. A lot of thanks for all, without your help i wouldn't see that problem. A big huge !!!
