I'm running the gamma backup launcher and a USB loader. What CIOSs and IOSs should I have by now? I updated my system to 4.0 a while ago , but I've downgraded back to 3.3. I might go back to 4.0 because I'm not sure what's causing my problems... Some games that people say should work with the USB launchers aren't working for me. They still freeze. So I'm wondering if maybe I've erased an IOS or CIOS that I should've have? What should I have for sure if I look?
