gaaaahh!!
finnaly.. i find some info with the same problem i have.
I modded a ps2 with magic3, booted a backup.. and worked great.
but.. on the SAME SPOT it locks up on Kingdoms hearts (in intro, with alice in wonderland.. and a few other places).
so, if someone can please confirm that this is really the case.. i dont have to unsolder the chip AGAIN
(maybe some info on whats wrong?)
