I downloaded the LARGE download for the SH3 and put MAMECE onto my storage card. I've tried to access games but it just gives me a blank screen. Any reason why?

Second, if i have other emulators using a gx.ll file or whatever will that one file do it for all of them?

Have you got, the roms in the right place?
say,
mamece/roms/????.zip


See ya Later
