cocktail mode help

[jrallen81]

Hi everyone,

I am modding an arcade1up head to head (cocktail), replacing the guts with a pc. Under video options, there is supposed to be a cocktail mode in mame but I literally don't see it. Or is the issue I need a different ini or layout file? I'm in over my head here if someone can help. mame documentation not that helpful.

In games that support cocktail cabinet modes you can need to hit the "Tab" button while in the game and then go into the "Dip Switch" option. You can change the cabinet mode there. I am not sure if Mame supports this for all games or only for those that traditionally were on cocktails. That is what the dip switch setting is doing is basically emulating what the original hardware options would have been.

I recently completed a cocktail cab build and the method that worked for me was to run my mame through retroarch.  Retroarch has a shader that will split the screen. "cocktail-cabinet.glsl"  Some games you may have to mess with the parameters to make sure your 2 split screen merge correctly.  But it's not too hard to do.  As far as just straight from mame itself, Unless it originally was a cocktail game (Pac-man, Donkey Kong ect...) you'll need to go into dipswitches and set it to Cocktail.  That will cause the game to flip when it's the other players turn.  If that is all your concerned about then that would be the method for mame. But needs to be done with every game you have set.  If you're looking for the split screen experience then you probably need to look into using retroarch since you will need to use the shader for that method.   Good luck
