You can try reconfiguring your controller in EmulationStation; this should rewrite the RetroArch autoconfig including the hotkey-enable function. If that doesn't work, however...
@retroprestoz said in Start button exits games without pressing select as well.:
A buddy of mine just put it together for me to use some I'm not exactly sure what he did or all of the config files and stuff.
Unfortunately, neither are we.
It is not practical to troubleshoot a system that neither you nor we have any idea how is configured. For that reason, third-party builds are not supported in any capacity.
Start here: https://retropie.org.uk/docs/First-Installation/#installation
I suggest you to backup your roms and configs, and then install the current latest official image for your hardware from https://retropie.org.uk/download.
Restore your backed-up roms but not the configs yet -- you can cherry-pick them later but if you blindly copy them all, the one that's causing your issue will come along with the rest of them.
