@olivierdroid92 Thanks. I already remap on retroarch menu. But A, R button of 2P is not working.
My favorite board is x64. I want to play tekken tag with my friend. tekken tag is possible playing in mame2010.
A, R button of 2P is not not working also on RP3, RP3+, X64 all board with all game pad, gpio too.

Hi @alexander, use the select button as hotkey. It has always been recommanded.

@leosabino Upgrade to the latest stable version (currently Recalbox 6.0 Dragonblaze):

You will have to back up your files and start from a clean install because the updater will not be able to upgrade from such an old version (there were many changes).
After that, test and return here to say if it solved.

@zachstep I did not understand what kind of setup you tried to do, did you map the control on Emulationstation and tried to set it up in Retroarch?

@acris Thank you!

@anthunder RecalBox 4.1 is a very old version, upgrade to version 6.0 RC2.

@erniman
If you want just look if the system is up or down, you can easly and just connect it (with resistor =>1KOhm) to the power pin of one USB plug. Because PI switch off power on USB if the system is down. Even when power subsist on the board.

@voljega : Thank you. I didn't know that.
