Is there a way to get a cocktail cab experience for basically everything on Rpi4?

@mitu Which file would I modify? /home/pi/RetroPie/roms/ports/I.K.E.M.E.N GO.sh or /opt/retropie/ports/ikemen-go/ikemen-go.sh?

Yes, that would be the start script. You'll need to add your own startx command there and make sure that the configs/ports/ikemen-go/emulators.cfg file doesn't containt the XINIT: prefix before the script, since that would start startx before your script.

@mitu Which file? I mentioned two.

@mitu I tried editing the /opt/retropie/ports/ikemen-go/ikemen-go.sh file like so and I keep getting errors:

#!/bin/bash
export MESA_GL_VERSION_OVERRIDE=2.1
xset -dpms s off s noblank
startx -g 1x1+0-0 -e --rotate right --reflect y 'cd /opt/retropie/ports/ikemen-go && ./Ikemen_GO'

This is the contents of the run log:

I already added my pi user to the tty and video groups, so I don't know what to do

This looks like an error from the legacy xserver wrapper - do you have the xserver-xorg-legacy package installed ? If so, remove the package and try again.
Does the command works if you're executing it from the terminal, after exiting EmulationStation ?

Jesuszilla

@mitu I do not appear to have that package installed.

OK, so the error is not caused by the Xorg wrapper. I don't know what's the cause of the error then.

Jesuszilla

@mitu I notice sudo startx has no problems starting but I just get a black screen and no audio. What do I do?

mitu

@Jesuszilla sudo is never the answer and it shouldn't be used as a brute-force option.

What do I do?

Try replicating what runcommand does to start an X session - using the same command and arguments and add your own argument(s) to it. Experiment directly from the terminal until it works, before creating a script to be run from EmulationStation.

Jesuszilla

@mitu Well I got a little further by duplicating runcommand,sh into a separate runcommand_cocktail.sh that I intend to use solely for IKEMEN-Go and other ports that don't have shader configurability. I successfully managed to get the image to rotate and flip (though the latter is not really what I wanted).

The contents of the file are as follows:
https://pastebin.com/tM4Qa7aB

However, the --reflect option appears to only reflect the single image (video is backwards; I tried both X and Y), not mirror an image on two sides like I want. What's the next step to mirroring the image on both sides? Do I need to set up a virtual output or something? What's a good guide to look at for this? I have to go the script route because xrandr returns "Can't open display" every time I try to run it, either over SSH or locally on the Pi, doesn't matter, so I can't even get basic monitor info this way.

Not sure what options are available for rotation, but 'xrandr' can only work from an Xorg session, not from terminal/SSH/etc. You can add the 'xrandr' command and its arguments to the 'ikemen-go.sh' script, before the actual port command and after 'xset' - assuming you're using the original script which uses XINIT: to start the port and not your own command line that starts the Xorg session

#!/bin/bash
export MESA_GL_VERSION_OVERRIDE=2.1
xset -dpms s off s noblank
xrandr # arguments here...
xterm -g 1x1+0-0 -e 'cd /opt/retropie/ports/ikemen-go && ./Ikemen_GO'

@mitu xrandr doesn't do anything if I put it there; it only does anything if I use a modified runcommand script
