On the GC, there are 3 known drive revisions, as http://tmb.elitedvb.net/dvd-game/index.php/DriveVersions explains. Now, there is a rumour that a GC-D2A chip exists, it was rumoured to be on a launch-day japanese cube. I would be very interested in knowing if this rumour is true, did anyone with a launch GC dare to open it and look for it? It's written on the small chip (CPU) on the drive.
i have a launch day us cube that i will be opening soon for inspection, i ll try and keep you informed ;p
I think might have some useful info http://www.ps2-scene.org/forums/showthread.php?t=52394 I have a LU 101X and is indeed a launch system. I had to pay a girl $100 extra for it because she waited in line for so long. Dang old women. James
