I can get USB Loader GX to run Black Ops ONLY when I install cios 249 rev20 base 57 to slot 249. If I install rev20 to slot 250, and attempt to load the game with 250, the game freezes at Loading. Setting the GX default to 250 dosen't help, either. The reason I want to run Black Ops on 250 is so that I can still have rev17 in slot 249, in order to run Triiforce. Have the latest GX; ran PimpMyWii 1.43; 4.1U; latest homebrew.
