Every thread like this usually has some noob asking dumb questions, which saves me the trouble of having to ask them. Looks like I get to be that noob in this one.
I copied the file over to my USB drive. I made the drive E. I copied the dolphin file into my documents folder. I ran the reg 1 and then merged reg 2. I made a shortcut on my desktop to the attract mode exe on E. It starts up fine and I'm able to scroll through all the machines and games. How do I actually start a game? When I press the A button on the gamepad, the game screen in the arcade cabinet blinks for a second and nothing happens. I've also tried hitting the start and select buttons, which seem to do nothing. What dumb thing am I so dumb that I'm overlooking?
