Hello room! Not sure if this is the right place for this but here it goes.

I have a modded 360 system. I’ve acquired several d/l’s. they say :

This release is pre-patched with SS, and stealth-patched with DMI and PFI Tested on a Toshiba-Samsung TS-H943 with IXtreme 1.3 firmware │ 1. Unrar 2. Burn with clonecd 3. Play and enjoy!

However only 1 burned copy works, the others say unreadable. Can anyone help me here. Thanks!
