12″ PowerBook G4 PT 4

Due to various factors, I’ve not had much of a chance to play with the PowerBook much this month, earlier this moth a follow up to PR/48740 happened, requesting feedback on new changes which had been committed that I’ve not had a chance to test yet.
One thing I did do tonight was to re-flash the SuperDrive with a RPC-1 firmware image which turns the DVD drive region-free.
The firmware images are hosted on MacBook.fr and cover Macs all the way back to G3’s.
Flashing was straightforward though I could only re-flash with the version currently on the drive. It was not possible to flash a newer stock or region-free image on the drive.
Aside from the firmware on the DVD drive, Mac OS also tries to enforce region locking, the Region X utility can reset the Mac OS related setting regarding content region.
