The region of Xbox 360 (PAL / JAP / US) is determined by a IC, same as Xbox EEPROM?

Would be possible change this region soldering a new IC of a dead Xbox 360 motherboard of other region?

Ummm im pretty sure the region setting is the bios and in that case, noone knows where the bios actually is. Some people say its in the the cpu. It may possibly work if we knew where the bios is and then solder that chip to a different mobo but to honest i have no idea.

No-one can be sure at this point in time as we have no extracted bootstrap, kernal, EEPROM... etc. files to do comparisons on in same region and different region consoles to identify the differences, but having said that i would be assuming that they did not make the same mistake this time as EEPROMS are reprogrammable and this has long been an excuse for modchipping consoles, my guess is that they would have put it in the bootstrap, and made the bootstrap OTP so that it cannot be reprogrammed (seeing as it is highly likely that the bootstrap is on the CPU bypassed either),

On another note in my opinion it is highly likely that we wont be able to do bootstrap and kernal comparisons as they would be encrypted with the consoles per box key (RSA-2048 breaking anyone? lets talk in a few thousand years). also as they are likely to be stored inside the CPU on data lines that never leave the CPU (or touch the BGA in any way what so ever) it would be a (unt to extract

So maybe it's "easier" to patch the games? What do you think..
