@agrajag Good times. I use my keyboard as my primary controller for my Daphne roms. Intellivision, because of its unique rotating dist controller, strikes me as a pain to use with a fight stick. I have used an 8BitDo SNES style gamepad to play Intellivision games, but it is not ideal.
Dumb question: How do you go about changing controllers? That part of Retropie is a mystery to me at this point. Everything I have running is setup to run on the Mayflash and since it's seen as a generic Xbox controller (and my other controllers are almost all Xbox wired and wireless actual controllers) I'm really concerned about being able to easily switch back and forth.
For example, I want to play the game Dungeon Explorers on SegaCD or TurboGrafx with four of us, but I have NO idea how to essentially remove the Mayflash, plug in four game controllers and have it all just work without screwing up all the work I did to get the Mayflash to work.
