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.
