Thanks. I have scans of the cases and that's what I copied the shape from and ripped the art from. There's a guy who has virtually all of these games and I think the background scans originated from his collection.
To keep everything consistent I decided to vector one so that it could be used for everything. I have a bunch of these done now but I'm not sure whether to continue or quit. Most of the games are pretty poor to be honest and I don't know if just retouching/photoshopping one of these units and doing some recoloring for the buttons would have been a more authentic and faster way of doing it.
