Need help with a game! (JoJo's Venture in MAME)

[Crash40]

1. download and extract the copy of Mame as suggested in last post
2. run it
3. find the game in the Mame gui
4. right mouse click on the game in the Mame gui
5. move the mouse to audit
6. left mouse click on audit

It will list any issues with the set

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.
