Thanks.
Sorry about that - naive mistake from my end on the random selection logic refactoring.
I just submitted a fix, and I'm providing a patched binary here:
https://github.com/pjft/EmulationStation/releases/download/2.4.0/emulationstation
In case you want to install it yourself.
Thanks for flagging this.
To install, exit ES, and in the terminal (or via SSH), run:
mkdir ES-update cd ES-update wget https://github.com/pjft/EmulationStation/releases/download/2.4.0/emulationstation chmod +x emulationstation sudo cp emulationstation /opt/retropie/supplementary/emulationstationand then reboot.
Should be good.
Sorry about that once again.
