Found it. I was misled by the official Rpi documentation.

rpi_config_txt_video_option.png

The solutions below only refer to the display rotation, see notes.

Solution 1: Legacy video driver config.txt: Neither dtoverlay=vc4-fkms-v3d nor dtoverlay=vc4-kms-v3d enabled, but display_hdmi_rotate=2 cmdline.txt: No video=... option

Note: The RetroPie Image for a Rpi3 ships with the legacy driver enabled. The EmulationStation binary is compiled against that driver and works out-of-the-box. This should also not affect any precompiled emulators.

Solution 2: (fake) KMS and Kernel option config.txt: Either dtoverlay=vc4-fkms-v3d or dtoverlay=vc4-kms-v3d cmdline.txt: Add video=HDMI-A-1:1280x1024@60,rotate=180. Note the use of HDMI-A-1 and not HDMI as the documentation (see above) states currently. (I have a PR filed for that.)

Note: You will have to source build emulationstation with that config to make it use the video driver. I did not testdrive any emulators with this solution.

@bluecoffee said in Pi4 with vertical screen orientation - newest advice?:

Suggests that I should be modifying the file autostart.sh.
Is this correct?

Yes.

Could someone outline the steps that need to be taken in 2022 using a Raspberry Pi 4.
There also seem to be lots of conflicting questions about

Does this only affect Emulation Station, but not the actual games themselves?

Yes.

Does this cause a performance hit like the old method did?

For EmulationStation, not so much.

Do I need to modify each emulator to run vertically as well?

Yes, though for RetroArch you can change the main configuration and it will be applied to each core.

See this topic for a similar question and some recommendations on how to rotate the screen.

Hey there @ajlino ,

I am in the same boat as you with this issue. I have a 2 player cocktail table built running Retropie on a Rasp Pi 3.

I understand that not many roms support cocktail mode where the screen flips for P2, but I was hoping at least games like Pacman, DK, Galaga would work since the versions of roms I have appear to support this. But for the life of me I cannot get this screen flip to work at all on any game. I did manage to get Galaga to flip for P2 but it was all messed up and not playable.

Did you ever have any success on getting this screen flip in 2p mode to work? It's frustrating seeing videos online of people getting this to work with no issue at all, and I am following the same exact method.

Yes, we need to document the rotation/size options. The screenrotate parameter should be 1 through 3 (see this commit), for your usage values 1 or 3 would have to be used.

Does rotation work without the super-resolution (with or without xrandr controlled rotation) ? What other parameters are you using for starting emulationtation ?

Run emulationstation --debug <plus your other params> and post the output on pastebin.com. Run also xrandr --verbose and post the output.

You need to give more details about your setup and what exactly have you tried - start with the info asked in https://retropie.org.uk/forum/topic/3/read-this-first.
The Pi4 doesn't support the same rotation options as previous models, so editing config.txt will not work.

I would add that in the /boot/cmdline.txt parameters, I changed the resolution to 768x768 and everything is now centered and looks correct....except, the top few lines of the [TAB] menu in Mame are cut off....

This is so strange.....

@dankcushions arrrrgh. Thanks. Definite performance issues when rotating the whole system, and PiFBA is the only core that's giving me issues otherwise. Now I'm off to see if I can compile FBNeo with Cyclone and see how that runs. Thanks for your help!

@djsinestro did you resolve? - pm me - pacman@videoarcade.tv

@MISTERHOLLYW00D said in Text Rotate:

Is it possible to rotate retroarch menu? When I bring retroarch up it’s still sideways

No, that's a RetroArch's limitation - even if it can rotate the emulator video, the menu's orientation can be rotated only when using the desktop display driver and it will not work on RetroPie.

You're using a PI3, so you can use the rotation offered by the firmware.

@mitu thank you.

At least it wasn’t a silly checkbox that I Missed.

@gomisensei That worked perfectly, thanks!

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.
