It depends on the emulator. It needs to provide a way to insert coins (or change dip switches for free play mode)

Ok, that's what I was leaning towards. I've tried all of the RetroArch NES cores and NES. emu, and it doesn't appear that they offer DIP switch support. I'm tending to think that there isn't an NES emulator on Android that does. Maybe I can find a MAME solution. I miss owning a PC. Thanks for your assistance. Have a blessed new year.
