Quite interesting.

> The software also contains code to properly handle Gamecube optical discs

I suspect this is the real reason behind the experiment. I've been looking for years for a way to get raw DVD data, to decode XBOX discs [1]. Why can't manufacturers give us raw access to the discs? Are they afraid we might use it to break copy protection schemes?

Yes. Many CD copy protection schemes worked by messing around with subchannel data, error correction and things like that.

Great Article!

Reading it reminded me (at least to the best of my knowledge at this point in time!) that THERE ARE NO OPEN HARDWARE CD/DVD PLAYERS.

I think some person or people should attempt a completely open hardware CD and/or DVD and/or Blu-Ray player...

I'd be happy with just a completely open hardware CD player...

Micah (Scanlime) did some work on a Bluray player. Brace yourself - this is a real tour the force of reverse engineering: http://vimeo.com/110257380 https://hackaday.com/2014/10/30/reverse-engineering-a-blu-ra...

There is another "independent" firmware for a bluray players, pirate one for Xbox 360 ones :) somewhat hard to get your hands on the source.
