I've installed 3.71 m33-4 and yes, I do have the 1.5 kernel add-on installed. It works fine for some homebrews such as gpsp and cavestory. But others like Tyrian, PSPRevolution and the Super Nintendo emulator refuse to boot. I've tried multiple times to just switch the kernels from 3.71 to 1.5 and change the folders they are placed in (GAME to GAME150 and vice versa) yet nothing I have tried is working in any way.
Can somebody please help me out here?
