I just got the 2.3 image. Having the same problem that controller two does not work in games (even though this command the controller will program, just not function. sudo chown pi /opt/retropie/configs/all/retroarch.cfg
cd /opt/retropie/emulators/RetroArch/installdir/bin
sudo ./retroarch-joyconfig -j 1 >> /opt/retropie/configs/all/retroarch.cfg)

F1 not working in games either. For some reason it only shows up if I launch and exit the doom port but F1 is never pressed, just shows up when exited out of the game and configuration does not save.

When I open the menu inside of emulationstation, there are some glitches with the menu. If I go to scrapper all the text inside of that are square looking letter instead of readable letters.

Also installed Quake 3 from the setup menu but when launching the game it says failed to launch and cannot find ioquake3.arm.
