Downloaded and put Mupen64 folder into the root of my HDD, put my roms into a different folder. I can run Mupen64 993 with no issue, but when i select a rom (Super Mario 64) it says it's probably not a n64 rom. I tried with multiple different ones with different file extensions, none of them are loading for some reason, i can only press B to go back to the selection.
Has anyone come across this issue before?
EDIT: Tried it again, this time using a usb drive and it worked, so for some reason it doesn't work from an HDD.
