You could check with fox1 here, or hobbyroms.com, but for that many roms you are almost better off learning to burn them. You'll likely pay more than a burner would cost to have someone make these unless you get a bro deal.
Thanks skate, I've been away from the forum for a few years and don't know who is doing what anymore. I've never thought about buying a burner and learning it since I see it as a one time thing, but I'll consider your advice. Thanks again!
