You should have the neogamma backup disc loader installed for disc loading, which should load most game disc. CFG usbloader will give you the most flexibility, after my guide it defaults to ios250 base 57 r20. But you can use ios247 r20 base 37 r20, ios249 base 38 r17, ios248 base 56, hermes ios222 base 38 ios223 v4 base 37/38 v4 ios224 base 57 v5.1. Most games will run just fine on base 57, some may require you to use the other. This is easy to setup in the game settings inside the loader. So at the moment, you have all the up to date cios, so if some game guide say use this ios or that, just set it to that in the loader. USB loading is more enjoyable than discs.
