Oh 😞 ok thanks a lot, I've tried Yoshi's Island 2 (edit 2 of course) on snes9x on the GPiCase and it is indeed unplayable, video and audio both very slow...

@dada_savi ES = Emulation Station, en el juego que desees, antes de ingresar al mismo presiona SELECT, ahí te va a dar diversas opciones, entre ellas cambiar el núcleo y el emulador.

I use that game, what you will need to fix that is to go to the main RetroArch's in game menu, go to the quick menu, controller and there you will need to put the 2P's gamepad as a normal controller instead of multitab, doing that you will solve the issue

@acris Je te prie de m'excuser. Je pensais que c'était un problème de matos... Je n'ai même pas imaginé que ça puisse venir de l'ému...

Vraiment désolé !
Merci pour votre aide cependant...!

Select the game in ES Hit SELECT EDIT META DATA Change emulator to libretro choose any other core instead of snes9x

Problema resolvido, vlw pela dica.

Or you can change the input to "none" for the second player in the menu of retroarch. (Hotkey +A)

Tentei mexer nisso, mas nesse retroarch tem tantas opções, ai achei mais fácil alterar o emulador como indicado pelo colega acima, mas de qualquer forma obrigado pela dica.

Ein anderer Weg wäre, via RetroArch den SNES Multitap zu deaktivieren.

Spiel starten Hotkey + B drücken Quick Settings auswählen Input Settings Player 2 (Multitap) auf normalen Controller umstellen RetroArch verlassen

Das natürlich nur, wenn Du einen anderen Emulator, als PocketSNES benutzen willst.
