Alright, well im a little further than what I was.
The two roms I was playing with now show up, and when clicked on, the screens come up.
They have a bunch of "garbage" until I hit the alt button on my keyboard, then everything looks correct and the screen goes into attract mode.
No sound, just picture.
What key is a "help" key for keystroke info?
I am just playing around with mame on this computer to get a grasp on how everything works, before i start building a dedicated unit.
