He won't give exact details as to how he did it though. This is all he said on another forum:
you Russian never give up i like that
you followed me here
as i admier your developer (NEMNO) AND some of you I CONSIDER FRIENDS TO ME (silentman) and (Alexandermoove) AND as UR NOT PART OF THOSE ASSHOLE AT 3DOZERO LIKE THAT LUNATIC 3DOKID i will tell you i managed to overclock only the gold star 3do by replacing two crystal on the main board
THATS THE ONLY HINT I WILL GIVE YOU. YOU CAN START FROM THERE
