@meleu I got you, that's exactly what I ended up doing. Thanks again for the assistance with that. Sorry I've had a long day and my communication skills are at a minimum right now which is what my wife has recently told me. ;-) Thanks again.

If your aim here is to play these games with two controllers but still choose the player you want, try using the 2-player clones.

For example, tmnt2po lets each player choose which turtle they want to be.

How did you "reset" everthing? I too was using tab to configure mame 2010. Trying to mess with player 2 in the tab menu, i changes all the n/a to "none" and now nothing works for player 2. Even binding my keys in retroarch on player 2 wont fix the prob. I think i have to reset the mame tab settings like you did.
Thanks
