I thought I should probably just add to this post rather than start up another one with the same topic.
So here goes.
I'm trying to get Snes9x happening and I've basically been using trial and error (Because I don't know what I'm doing). Thus far I've managed to start it up by using ./ssnes9x bman.smc and it'll tell me which switches I can use, etc.
So basically I'm disabling everything I can, and I end up putting in
./ssnes9x -r 0 -nojoy bman.smc
Which disables sound and joystick support (Fine by me, I don't have a joystick). It'll tell me a bit about the ROM and then say

/dev/js0: No such file or directory
svgalib: Cannot get I/O permissions

and just stop there.
Can somebody please tell me what's going on, or what I can do to avoid this?

Are you root when you're trying to run it or you're a normal user?

Yeah, SNES9X requires access to svgalib, which means there are two options:

Change access of SVGALIB to yourself
or
Run the "su" command and change to root

But to be honest, get and try ZSNES, it's TONS better,you don't need to be root, and has a GUI interface.
