The games have been opened, but are back in their original boxes and are still with their original batteries. They're all in good, lightly used condition. I'm looking to get $110 shipped for the set, and can only ship to the lower 48 states.
Use DiscJuggler to burn the discs. That software works far better than IMGburn, and with it you're able to get games to boot that won't work when trying other software.
To get past encryption, there's Jagtopia which will let you run any game that can't boot on its own. It's free and you can burn it to a CDR.
