i put ps2psxe in the MC0:boot/ folder and specified the path, and it shows that the path is MC0:boot/ so i know its working.
i try and do Start Emulation or whatever and it says "cannot find ps2psxe in path" or something like that. i tried googleing and the only "solution" was to specify the path, which i did
if i specify the path on USB it works fine. even if i specify the BIOS on MC and PS2PSXe on USB, it still works. so i have a feeling it has something to do with ps2psxe being on the memory card.
