How do you want these formatted? For Nintendo DS cases? Do you need custom covers, and if so, do you have a particular template that you'd like me to use? Or, would you be happy with just the scans?
Both Match of the Millennium and Metal Slug are already up on the site, just as an FYI.
I've got Metal Slug (US), Millenium Fight (US), and Bust-a-Move Pocket (the US version of Puzzle Bobble).
