I had the same issue on my PC with that stick. There's a TINY little note in the instructions that I found:

"DINPUT Mode: press and hold 'Start' and 'Y/triangle' for 3-5 seconds to switch to DINPUT mode."
(with the switch down in DIN/PS3/SNK position)

That might help.

@daviddraper said in MayFlash F500 configuration:

@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.

David,

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.

@djinnocide Thank you for your help. I tried to do a reset of the configuration, and now it works. But I had to configure every emulator for the Fightstick, one by one to make them to work.
Maybe it can be the new version of RetroArch (I noticed there's a new graphical interface). In the older version the configuration it was automated for all the emulators (maybe also in this new version, in different way).
Now it need some work to configure the keys and find the correct mapping but it's ok.

See you.
