I solved my own problem! I modified the EmulationStation startup script to toggle back and forth between horizontal and vertical mode on a restart. So, now I can rotate my monitor, restart EmulationStation, and my menus match the orientation. Here is the updated file: /opt/retropie/supplementary/emulationstation/emulationstation.sh #!/bin/sh esdir="$(dirname $0)" while true; do rm -f /tmp/es-restart /tmp/es-sysrestart /tmp/es-shutdown "$esdir/emulationstation" "$@" $rotate ret=$? if [ -f /tmp/es-restart ]; then if [ -z "$rotate" ] then rotate=”--screenrotate 1” else rotate=”” fi continue fi if [ -f /tmp/es-sysrestart ]; then rm -f /tmp/es-sysrestart sudo reboot break fi if [ -f /tmp/es-shutdown ]; then rm -f /tmp/es-shutdown sudo poweroff break fi break done exit $ret

@mitu ... Will report back lol

I'm using the following setup: Raspberry Pi 3 Model B RetroPI: 4.5.1 Retroarch: 1.7.6

im not sure what your issue is here the tate mode does rotate right this is what arcades do

@chizzer thanks for the reply ill give it a shot

@polyfusion said in Help - Retropie Rotate 90 degrees with 4:3 Aspect Ratio: . I'm using a 64GB image that has version v2.7.3RP What do you mean a 64GB image? Retropie isn't available as different images. If you got a third party image from elsewhere, you really should be looking there for support.

I found one! A friend asked me for a seperare Tate-Card to switch to when using his Tate-Display. Simply use the Arcade-Sytem instead of seperate Mame and FBA-Systems. Enter a game with Mame2003-core, activate rotation and save the system configuration file (not game or core override!). Done. The rotation setting will also apply to all FBA-games.

@langest said in Possible to rotate screen per rom file?: Now I am only wondering, where should I put the rom specific file? As the posts above said - and it's also mentioned in the Docs - , next to the ROM file.

@cybermrc you probably figured this out by now, but the cocktail switch only serves to flip player 2 upside-down. It won't induce the initial rotation.

I'm thinking about a cocktail table and was wondering if you ever figured it out?
