Okay, thanks for the unzipping tip. Newb problem, but I was tired last night when I was trying it for the first time. Now it says that it loads it, but it doesn't do anything. It's just a blank black screen.
[20051222.03:12:01] FAIL: MMU9: Zip file has no GBA binary. I get that when I try to run ROMs on DSemu. Can anyone tell me why or how to fix this problem?
