Maybe (probably?) I'm just doing something wrong....
I just tried to take a sneak peek into some 3.60 .PRXs (from the Slim), and when trying to use PRXTool on them I always get this:
Assertion failed: m_pElfSections != NULL, file ProcessElf.C, line 478
Yes, I *DID* decrypt them, doublechecked with a hexeditor ;)
