Basilisk II PSP Problem

I got your "mac.rom" but it boots to a floppy w/ question mark and by common knowledge
it means error xD
i made my school comp do this once when i was very little hahaha xD
But i mean Im not sure if someone got this emulator working?
or not,.
;/
Im not asking for the image specifically ( I KNOW I CAN"T FRONT ASK IN FORUMS)
but if someone knows where i could get full help on how to run this emulator and such
thanks
