Thanks for the clairification. I'm trying to test a few different versions of MAME, I have (I think) all of the proper SNES bios' and a game. I cannot load the game via MAME32, but in the command line versions 131 and 136 I can load the bios' but when I select the SNES one, I type ok, then get some load sucess screen and then blankness. Any ideas?
