Apparently, I am unable to enable the SPU IRQ hack with ePSXe. I checked the option to enable it, but the sound was still messed up in Metal Gear Solid. I restarted the emulator, and the SPU IRQ hack option was disabled again. Can someone explain why this is? The SPU IRQ hack works fine with PSXEven, but unless I'm missing something I can't use my gamepad with PSXEven. So, can anyone either tell me why the sound hack doesn't work with ePSXe, or how to use gamepads with PSXEven?
