    iMame4All has slowdown in some games because it posts too many error messages to the console. eg Robotron 2084 (note: you have to select ‘Content Settings’ > ‘Restart Content’ in the retroarch GUI after you get the “Factory Settings Restored” message, else it will hang) – you’ll notice that when the player spawns at the start of the game, it slows to a crawl. The reason for this is it’s logging a load of error messages to the console.

    If you instead amend /opt/retropie/configs/mame-mame4all/emulators.cfg to
    lr-imame4all="/opt/retropie/emulators/retroarch/bin/retroarch > /dev/null -L /opt/retr(etc...)
    …it doesn’t display these messages, and the game plays flawlessly. Apparently this affects other games (outrun, others?)

    I’ve logged an issue both with iMame4All-libretro, and Retropie, so hopefully a fix will eventually be made, but if you don’t care about error messages and want to use a libretro mame emulator, go ahead 🙂

    Is the way to update my pi to run the setup utility again after updating?

    Thanks for the fix!

    you need to go to option 5 in the setup menu (install individual emulators) and then choose lr-imame4all, then rebuild from binaries 🙂
