Whelp, I figured I'd give it a shot, it's probably not perfect for everyone, but it'll work just fine for me. Here's a link to the cover:
http://i.imgur.com/AkTw4AE.pngI remade the Dragonball logo from scratch in Illustrator, and the border that is used on the famicom version of the game, "Shenlong No Nazo". I also took inspiration from the french release of the game, Le Secret du Dragon, and used the copy from the back as well. The image in the center was beyond saving, and I didn't want to spend the next week digitizing it, so I found another high resolution image from Google and scaled it down to fit the border.
So I suppose it's a custom cover, inspired by retail releases.
The cover is actually going to be for a copy of Dragon Power I've got, which was originally a Dragonball game, then modified.
