dugan26 Posted October 6, 2022 Share Posted October 6, 2022 Hi All - Thanks in advance for all the support. I finally have configured Mame and my arcade games with the help of this forum. i am having an issue on games like Donkey Kong where i want to use two players with two controllers. My current state is i have two players playing but sharing a controller - meaning passing it back and forth. However when i play Gauntlet i can play 2 players same time with two controllers. What am i doing wrong? Quote Link to comment Share on other sites More sharing options...
Lordmonkus Posted October 6, 2022 Share Posted October 6, 2022 You need to map player 2 controls to the 2nd controller. Quote Link to comment Share on other sites More sharing options...
JoeViking245 Posted October 6, 2022 Share Posted October 6, 2022 At least for keyboard inputs... Even though (for some reason) MAME shows P1 and P2 in the Input Assignments, it's still an alternating controller game. Whereas Gauntlet can actually be played with 2-4 concurrent players. Your DK work around is to double up the P1 input assignments. The problem with that is, while P1 is playing, P2 [controller] can mess with P1. At least that's what my testing came up with... couldn't get P2 to have its own key assignments. I don't know if it's different using actual controllers (like Xbox controllers). Didn't test it.

Just spit balling here, but maybe using cocktail mode and some custom layouts might be able to get the results you are looking for. 1 Quote Link to comment Share on other sites More sharing options...
JoeViking245 Posted October 7, 2022 Share Posted October 7, 2022 Did some more testing based on what @Headrush69 said. Setting the DIP switch to cocktail, then restarting/resetting the game does make P2 controls work as assigned. But if you're on a single upright monitor, the screen does go upside down for player 2.
