yep that's correct. however new games have the media check. to get around this install the x2 4977 bios on to you'r chip but if you can not just use a tool called iso craxtion to patch the .xbe files prior to burning.
you can get craxtion from here
www.craxtion.com.
p.s before people go all postal and complain. isocraxtion does not use any microsoft copyrited components so it should be safe to post the location here. if the mods do disagree with me just remove the address
