I keep reading here and there that some DC games require 90 minute CD-Rs, and that you have to overburn them, and that's all well and good.
I have one question, though: where the heck do you get 90 minute CD-Rs? It may be because I live in a small(ish) town, but Walmart doesn't seem to have 'em... also, what size are most Dreamcast images, when all is said and done? The only CD-Rs I have right now are 700MB, and if that's enough for JGR and maybe Marvel Vs Capcom 2 then I'm content (for now).
