Yet another person in need of Killer Instinct help. It starts to work, but...

[Aqua Bill]

Okay, so I have everything I need. I'm using U64, i have the .img. I have the rom. It starts to work, but at soon as i press a button, an error pops up. I don't know what the error says, because it goes away instantly. I can safely watch the opening... over and over again, but I'd like to give the actual game a try. It's only after I press enter.

Its Killer Instinct 1 by the way.

I've been doing this for 4 hours now, please gimme some help?

Have you tried with MAME?

[Aqua Bill]

I have, but it doesn't even start with MAME.

Wow, I'm just not too bright. All I had to do was refrain from pressing enter, and instead press the previously-set "START" button. All this work over my own stupidity.
