I know you already bought the boot cd, but they also have a Game Hunter available for $13 USD from
www.consolesource.com that I purchased to play my backup CD's. I too like the idea of keeping my originals in a safe place.
You can add cheat codes to the hundreds that are already there on the Game Hunter. I was told by the tech support people from where I bought it from that it has room for 10,000 more codes.
