Thanks! Helps us noobs get a better understanding of things! I didn't know you can play either player 1 or 2 for 4 & 8 way. I thought player 1 was player 1 and player 2 was player 2....good to know thanks! Let me clarify, you can play a two player game (4 way) from player 2??
Yes, I will be showing this in video 3 but here is a summary. Everything in MAME is controlled in either of two ways...globally or via individual game settings. Individual game settings override global settings. So for a 4 way 1 player exclusive to the player 2 stick you configure MAME individual game settings.
For example...if the game is Ghost N Goblins (which is one I configured this way) you would go into the games individual settings (TAB key on loadup) and simply map the controls for player 1 to the 4 way player 2 stick. You delete the default settings then for up push up on the player 2...down same and again for the buttons you require. Then every time you load Ghost N Goblins it will be configured to play single player on stick 2.
