Xbox 360 region backups



Dear all,

I have some problem when i run backups on my 360 about region code. My xbox 360 is asian, but since i relocated i have to use the euro discs and turn them into backup then burn them for it to read it.

The problem that i have is while i can play original asian games, and backup euro games, whenever i use an US game then back it up i got incorrect region code :s

Is it due to something special ? I even tried with some pre-patched dumps that u can find on the net, but whenever it’s an USA backup it doesn’t work…
