i have cfw on both my slim and fat psps. I watched a youtube vid on how to do it, installed the emulator exactly as he did, and it says that it can not play the emulator. it also shows that a few of the folders are corrupted in my memory stick under the game blade. Is s9xTYL-0.4.2 not compatable with 3.71 m33, but is compatable with 3.71 m33-4? If that's the case, how might I upgrade to the -4 variant?
