Has anyone got a working configuration of Retropie working with both the Picade controller and a second USB one for player 2?
Picade works perfectly. I plugged in a USB X-Box 360 controller and configured that using the standard tools, and that works fine. The problem I have is that they both control player 1 and don't appear as player 2 - so when I press start on either the Picade or the Xbox controller, the game pauses rather than adding player 2 as a new player.
I've tried manually adding the button configuration to retroarch.cfg but got nowhere with it - if I disable the autodetection then I get nothing working on the USB controller once I get into the games (RetroPie menu works fine, but the game doesn't respond to anything).
Any ideas? There are some good two player games out there that would be great, and some not so good ones (eg Raiders of the Lost Ark on the Atari 2600 needs two controllers!)
