I plan on creating dumps for the following Xbox 360 discs that are marked as undumped:
Halo 4 (Disc 1) (Poland) - mastering code 1F887267
Call of Duty: Black Ops II (Poland) - mastering code 54A88BB6
Additionally I plan on verifying Xbox 360 versions of FIFA 12 (the one with Polish language), Prince of Persia (also the one with Polish language) and Rock Band (Europe). Also filling missing data like barcodes. Later on I'm gonna go through my PC game collection and see if I have anything useful.
I recently acquired equipment necessary for dumping and confirmed it works correctly by doing my own dumps and comparing hashes.
