Everything fine with 1.2.0.5. I'm not sure if this was happening before or not, but when I enter the menu (by pressing the START button) and then return to the game list, it displays the USB games. It's not a major issue since I can change to IDE again. Everything else seems to be working...
1.2.0.4 Beta
* PS2 Fat SCPH-50000 NTSC-J (without modchip)
* Running OPL From MC0
* 1 USB (32GB) / 1 iHDD 1TB / 1 Generic MC (64MB) with FMCB 1.966
Steps:
I set the compatibility mode (1, 2 and 6 just for testing) for Guitar Hero, then pressed back to the game list and this error appeared on...
Some problems that I noticed.
Running OPL from MC0/MC1 won't launch any game, my solution was running it from the usb instead.
Transformers, Downhill Domination & Crash Twinsanity wont launch with exfat, I tried later with Winhiip and works.
Some Games running fine atm:
God of war I
Burnout...
