Yes, I have a BIOS. I tried another one, just in case I messed mine up. But, after a couple of hours, I finally figured out what the issue was. I was using an ISO. In the help, it said that ISO was supported, but it wasn't working. I switched over to a .bin/.cue, and things started working beautifully. (btw, what does a .cue file do?)
But, back to my confusion, is there a list/description of what each option does both technically and practically?
Also, I have been trying to save the file path for both save states and the in game saves and whenever I navigate to the desired directory, there doesn't seem to be any option to set that directory as the one I desire. Any hints? Thanks again for the help.
