@spyhunter10 Do a clean install of the latest version of Recalbox and try again: https://archive.recalbox.com/ Did redoing the installation solve the problem? If not, what hardware are you using? Are you using the correct BIOS? Is ROMSET correct? Have you tried changing the emulator / emulation core? To avoid problems with Arcade games, read: https://github.com/recalbox/recalbox-os/wiki/Easy-Arcade-on-Recalbox-(EN) https://github.com/recalbox/recalbox-os/wiki/Advanced-Arcade-on-Recalbox-(EN) https://github.com/recalbox/recalbox-os/wiki/Check-your-roms-version-with-clrmamepro-(EN) https://github.com/recalbox/recalbox-os/wiki/Add-system-bios-(EN)

@Yonder Hi For God Knows which reason, retroarch defined buttons like : 1 -> B 2 -> Y 3 -> A 4 -> X Which is totally illogical with their idea of A to validate and B to cancel (thus making it work with any pad). BUT : you can use the "core remap" feature : buttons will be remapped according to how you set them up. You do it once for all for every 8bit core

For now it's not officially supported.
