Since i have finally aquired a copy of Castlevania for the saturn, i need a system to play it. i can find them easily, but was wondering which is the easiest to make it play imports/backups. Any suggestions on which chip i should get and links to where to get one? thanks
To play backups, yes you need a modchip. You could also try the swap trick. These are the only two methods for playing copies. Neither helps you if you have imported games (copied or original).
If they are copied imports you can use Satconv to make them compatible with your system. If they are original imports you will need to use an Action Replay (or similar) or copy them and use Satconv. Ripping/burning/copying guides in the Miscellaneous section.
