Whether I use RetroPie as my frontend or Emulation station… I’ve used them both loaded on different SD cards… and every rom in my in my inventory whether it’s NES, SNES, PSX, MAME, etc… I do not get the “insert coin” at the bottom of the screen… For use with the coin mech… Some people say they have to use tab or k as a hot key to insert credits before playing… mine just says press start or nothing at all… I want to be able to make people insert a coin in order to play.
