So we were having a discussion the other day on how mod chips for game consoles work. Well, here's an explanation.

It was pretty much like I figured - there's uncopyable data on factory discs, which of course won't appear on a copied disc. The modchip helps compensate for this using a microcontroller (which is typically a simple CPU packaged with other stuff like memory all on a single chip).

I don't know what the deal is with Playstations and black CD-Rs, though, and if they really do work or not. Seems to me like they shouldn't work without a mod chip, even if they're as black as the night itself, mayor.
