For example, with Lovers in a Dangerous Spacetime, it worked great the first time, but then the next day when we fired it up, we can only get 3 players to work (2 controllers and 1 keyboard). Unfortunately when I play other Steam games I'm having serious problems getting them to work properly when there is not a single-keyboard-for-multiple-players support. Usually these work relatively well for MAME and I can make them work fairly well with other games via JoyToKey (especially games like BroForce where one keyboard can be arranged to control four players at once). I have 2 Mayflash F300 Arcade Fight Stick Joysticks and 2 Mayflash PS2 PS3 PC USB Universal Arcade Fighting Stick Joysticks.
