Err... There were a lot of different versions of Jojo, but I recognized the one I've been downloading(USA 981202) It said On ROM Check: "Best Available" so I clicked it and it worked! O.o It's now "Rewriting Data" and says it'll take a while. I have no idea what I did, I have about 5 different ROMs and 4 different CHDs and Idk what's working or not, and I have the exact same setup on both my other MAMEs and I have no idea why they don't work there :/ but I don't mind... thank you so much! If I stumble into any problems, I'll let u know.
