Try burning at 4X first cos thats the most obvious solution. If it doesn't work and you really want to rebuild it http://www.exploitstation.com/videos/cdvdgen.htm but it seems pretty pointless to me
SO just use DVD loader and it will work! You DON'T have to rebuld it. and if you want it to work with HD Advance or HD loader Download this patch from ps2hd.com.
Hi Folks,
if you like to play psychonauts via HDD,
you need the ToxicLoader.
This is a version of HDLoader with the code-core of ToxicOS 0.2. It is known to enhance compatibility with some games. This version also has the "crazyc" patch applied, as well as all other ES recommended patches. Includes 48bit LBA support.
you'll get it there:
