I'm not fully following you. Replacing the Zinc.exe in your Mame setup with an AutoIt wrapper would do the trick based off the rom passed to the wrapper. I'm just not seeing the need for Joy2Key...I understand that s11 requires a different controls binding...but that can be switched out by simply telling ZiNc to use a different config....say we have two different ones CRTL_SYSTEM11.cfg & CTRL_OTHER.cfg by passing the ZiNc executable CRTL_SYSTEM11.cfg when launching a System 11 game, would result in the correct controls for System 11....when playing other non System 11 games passing the ZiNc executable CTRL_OTHER.cfg would then result in proper controls for non System 11 games....that is IF we are only dealing with two different configs being required. hmm actually maybe I can do it myself based off your above config. [player1] coin=j1b9 start=j1b10 right=j1right left=j1left down=j1down up=j1up btn9=j1b1 btn10=j1b2 btn11=j1b3 btn12=j1b4 btn13=j1b5 The above over all works okay. I've attached a file that lists what system a given game is to, rom name, and numeric value used to pass to ZiNc.exe * Update * Uploaded some base control configs based on what Adultery & TX_TRINITY posted above. These appear to be working fine with my Logitech Dual Action thingy-ma-bob. Now the question is...should we just leave it to base configs per system...or should we get out of hand with things and do up configs that have combo's where they apply? I can code in a wrapper to apply these ether way, to ether by altering my prior wrapper or creating a new one that plays nice with how GameEx has things done. I'm just looking to see if there is interest and help creating the combo's. * Update Again * Now have a full set of all 8 systems...that said I'm still not happy with things...button placement can very greatly from game to game...so thinking of going to per game configs...rather than just bulk system ones. * Update Another * Added FX1 per game configs Added RZ per game configs - Missing Bloody Roar 2 (JP) Added S11 per game configs - Missing Prime Goal EX (JP) Ver. A Added S12 per game configs Added TPS per game configs Added ZN1 per game configs Added ZN2 per game configs Missing all KN1 game configs
