I've changed my region in the eeprom to region 2 for a PAL xbox.
Does this mean that PAL/NTSC-U games will not cold boot before nkpatcher does (UXE installed)...?

If so... great, can't think of ways to f*ck the exploit. otherwise... meh sad.gif

that's pretty much the case. the game will only cold boot if it's own region is being used in the eeprom. the exception is multi-region games...they will always cold boot

You can set nkpatcher shadow eeprom up, and then experiment with different settings to see what can happen smile.gif

If you change it to other region thats not 1,2 or 4 on the real eeprom you will have absolutely nothing to boot to because the bootstrap xbe for UXE can ONLY be run with one of the 3 regions.

to completely stop coldbooting from retail games zero out the language ID in the eeprom.

It should be possible to set the region to 0x8, 0x10 or any other power of two up to 0x40000000, because the UDE/UXE update.xbe has region flags 0x7fffffff. Multiregion games (with any combinations of 1, 2 or 4) wouldn't then boot directly either. Not tested though so if you can't recover then don't do it.

It's cleaner to zero out the language ID, because the kernel won't even try to load d:\default.xbe then.

EDIT: note that xbedump will forcefully set regions only to 0x80000007, so that would need to be modified to e.g. 0xffffffff.

Yeah... i zeroed out the language ID. Too bad i don't have any games to test it... are the XBL Arcade files legal to distribute or not?
