Hello again! I'm working on an arcade machine i have here at home. using Arpicade, The monitor as opposed to cga/tube is now VGA. as the arcade didn't come with a CRT Tube monitor.
I'm using the Mame 251 as it runs the game perfectly, and uses the trackball controller perfectly (It's a racing game that uses an opto board as opposed to a pot, so it acts like a trackball as the opto IO board is a track ball variant)

Now. everything is perfect. but when i run the game. the game will run horizontally perfectly. but squished to high heavens vertically. in the video mode of Mame 251, if i set the 'non-interger scaling' to Y only, or 'On' it fixes this issue. but then if i exit. or restart the Raspberry pi. it'll reset what i set the video mode to. and cause it to revert back to the squished picture. as 'Non Interger Scaling' reverts back to 'X Only'

Any clue on how i could fix this? I feel dumb for asking. but i've been searching through the SD card partitions trying to figure it out and i'm just incredibly dumb it feels like ahaha

Hello ^^ i've seemed to have gotten it all to work after much tinkering around. Everything works perfect now except that the Audio i can't seem to figure out how to force out through the headphone jack of the Raspberry pi 4, adding amixer cset numid=3 1 to the run.sh's did not seem to fix it.

Edit: Ended up fixing this too by changing the config.txt file aroudn a bit in the boot parition. However if you intend to do stuff like this you should use a separate powered amplifier between the sound and the speakers because hte sound is rather low otherwise. using USB speakers plugged into the RP4 causes a grounding loop and insane EMI/noise to rip out.

Glad you figured it all out.  Sorry I wasn't around to help.

Was that using ARpiCADE_4 or _5 ?

No worries,  i saw you had some life things going on so i understand :3

It was the Arpicade 5 image. For some reason or another when i use Arpicade 4 with my Raspberry pi 4, it says the image is out of date, and i need to update something? I couldn't figure it out. luckily Arpicade 5 just immediately loaded up no problemo.

The controls of the arcade machine are using a Trackball Opto board. to wire the steering wheel using the original Opto board, i used a Ultimarc I-pac, and wired it to move on Y axis for the trackball section as opposed to the spinner section. So for future reference if people here intend to use Arpicade with real hardware, Assuming your arcade machine uses a Opto IO board for your steering wheel. or a trackball ect ect. I-pac will support it out of the box with Arpicade. 

Something i should note about using USB powered speakers. On my Raspberry pi 3. i'm using old compuet speakers that plug into the USB port. the same ones i tested on the RPi4 with the EMI noise. using a Raspberry pi 3. the speakers exhibit 0 noise. Possibly something to do with the power of the raspberry pi? or perhaps the way the Pi 4 is versus the Pi 3? Couldn't say. butr basically the take away from this is. don't go out of your way to buy a different amplifier or something to power the sound if you already own speakers that plug into the 3.5mm jack on the RPI4. it might work with no noise.

Hello RubyRoo, I'm struggling so much with all this and it seems you might have fixed an issue I have.

Were you using an LCD with VGA or CRT? I can't get any signal through RaspbettyJAMMA, and HDMI out from the pi gives me a massively squished horizontal image.

I've been chasing my tail for weeks and I'm about ready to give up. What edits did you make exactly to the config file to get it all working?

Thank you!

What's happening:

Pi5 + RasberryJamma attached to arcade controls via Jamma, and VGA to old Dell LCD (1920x1080).

Qsound, SSF2.zip + SFXJ.zip in Arpicade roms folder, and highres.txt in root. Run.sh updated with /boot/firmware/launchers/mame251.sh ssf2xj

Pi boots, reads highres.txt and reboots. VGA monitor does nothing, stays in low power mode, doesn't recognise a signal.

When connected to HDMI directly into Pi:

Pi boots to Arpicade menu (4:3). When game is selected it plays in a very long, thin ratio.
