I'd like to know what I'm doing wrong since I see no interface, it just
returns nothing and quit automatically.

I have no playstation graphic bios downloaded, but I think it should at
least give me an interface right?

I do have my original ps1 cds backuped as ISO inside my hd and so I'm not
with the cd inside the driver...since I intend to run my ISO.

The question is what should I do?

Even if the problem would be that I have no graphic bios downloaded I
wouldn't know where to store the bios files.

I've tried to search on google but I got no useful results to me, most of
them were talking to linux users and there seems to work ok with no extra
setup.
