loadman does understand what I'm after.. If I launch a game from the 270 orientation (as opposed to the 90degree orientation), I want the ability to remap the controls on the fly so that the launching side act as player 1 and the opposite side act as player 2 (when by default they are mapped in the opposite direction). I can do this manually by calling MAME with an alternate ctrlr file on games I'd like to do this with in this case.
Simply remapping the game controls is not always an ideal solution, because there or some games I want to be able to be launched from either vertical orientation (ie, walk up to whichever side you want, and the launching side becomes player 1).
Rather than a plugin solution, I'm requesting as a future feature request for mala, that this could be an option added to the MAME Config>Options>Auto Rotate section where only available when "Rotate MAME with MaLa" is selected and allows you to pick a ctrlr file to use for each orientation (0, 90, 180, 270). Just a thought...
Anyway, just a suggestion, still LOVING MaLa as a frontend. -james
