First off, as a recent LaunchBox Premium member, I have to say well done on LaunchBox. Looking forward to playing around more with BigBox mode.
The past couple days I've been setting up my wireless 360 controllers for my various emulators, which for the most part has gone quite smooth. There is an issue though with Mame. When I play games with two players the second controller will not work. Well the controller kind of works. I can add coins, and the two player start button seems to function fine. However, when it comes time for player two to play you cannot move/shoot. Player 1 controller works fine.
Here is the strange part. It only seems to happen on games where two players take turns. I've tested it on Galaga, Dig-Dug and Burger Time. Games where two players are playing simultaneously both controllers work perfectly. Games that work fine for example are Metal Slug X and Street Fighter 3.
Hopefully it's an easy fix that I've simply overlooked. I've sent last night and some of today trying to figure this out. If anyone has experienced this or has a solution it would be greatly appreciated.
