My friend got a used PSP2000 on firmware 6.60 Motherboard is a TA-085v2 It was successfully modded to 6.60 ME1.6 it can't play ISOs at all, with or without an ISO loader. Did I miss a step, is there something else to enable playing backups? I've googled the crap out of it but clearly i'm blind. I can't find anything, no tutorials, nothing. It's like 6.60 came out yesterday or something.
