4 Controller working but not ingame

gzuz

Hey, im new to retropie and my only goal was to play games with 4 or more players. Everything worked fine until i wanted to play with more than 2 Player. My controllers are all connected and working in the menu. Once i start a game (snes or ps1) the controller are still recognized in the bottom left corner. If i want to chose players im only able to chose for Player 1 and 2, all other controller are not working anymore in the menu. I read a lot about "multitap" and that i have to enable it with hotkey+x in the game.

Problem 1: My main controller dont have a hotkey
Problem 2: A controller with hotkey leaves the game with "hotkey+X" and doesnt open any rgui

I googled a lot but i dont really understand what to do since i cant open anything with hotkey+x or select+x...

Pi Model or other hardware: 4,B 2GB
Power Supply used: 5V 3A ISY
RetroPie Version Used: v4.7.1
Built From: Pre made SD Image on RetroPie website
USB Devices connected: 3x PS Controller
Controller used: 2xDATA FROG Classic, 1x Shanwan PS3 (i tried also 2 bl ps4 controller)
Error messages received: -
Verbose log (if relevant): -
Guide used: -
File: -
Emulator: lr-pcsx_rearmed

I would be so happy for any help!

Only the P1 controller has access to the Hotkey, so you can do any configurations for a game in the RGUI with a controller that has a hotkey defined (the one you chose when you configured the controller in EmulationStation). Make sure that controller has also an X button configured, otherwise you can't open the RGUI with the Hotkey + X combination.

To enable Multitap - and get more than 2 players working - you can do so from the Options menu, where you need to toggle on the Show other input settings, close the RGUI, then open it again and in the same Options menu, can set _Multitap_1 to ON and Pad 2 to Pad 4 to dualshock.
Since not all games support Multitap and enabling it globally would probably break input for it, make sure that you use the 'Create Game Options file' menu at the top of the Option list, then toggle off the Multitap option(s).
