Hi there I just want to tell you guys that the warning screen DOES NOT appear on Japanese XBOXs. I'm pretty sure it is about some region thing on the DVD-ROM.
I have the clear japanese limited edition, i swapped in a US motherboard to allow it to play US games only. Using the original RCA drive, when it loads DOA3 and DOAX, the warning screen doesnt show up, it goes straight to the NINJA team screen.
Then I added Xcuter 2, and tried to load DOA3 and DOAX again, still no warning screen.
But then when I swapped in a Samsung drive from a US xbox, the screen started to show up on both games. In other words, before putting the samsung drive in, i NEVER knew that there was such an annoying warning screen.
BTW, i cannot explain why the warning screen is still loaded when the game is dumped into the HD.... I just wished that someone could find out how to remove it
