Well, thanks for coming back with the solution and happy gaming.

@ProjectMars Did you save a game preset/override with these settings ? Check in \\retropie\configs\all\retroarch\config if you have any game override saved and delete the file.

@mitu jajaja!! Yeah, between a messed up menu and non centered menu I prefer the not centered one that is redeable. Thanks.

I will edit the autostart file and see what happens when I connect it back to an HD screen (so I can prevent any surprises if I ever take the Pi to a friends house)

I love this theme sooooooo much. I'm a proper 80's boy!
Is there a way to extract the music from this image please Coin Junkie?
I have FTP'd into the image but can't see the audio files?
Thanks for the great Theme!

@mitu Yes i edited the XML file. The default was 1920x1080 and i changed it to 640x480, which of course is 4:3.

@ss3000

Try setting the overscan in /boot/config.txt using:

overscan_left= overscan_right=

Edit: Of course if that works, you may have to reconfigure your RetroArch display settings to accomodate.

We don't support third party images. Start from scratch with the images hosted on this site and then people here will be able to assist.

@kessler94 Press Start+X to open the RetroArch menu, navigate to Settings -> Video -> Aspect Ratio, and change it to something you like. When you're done, remember to go to Configurations and save your changes.

@wheeliebar overscan_scale=1

@dankcushions Got it to work! My menus say Apect Ratio INDEX, and it's on a screen where the text runs off the edge. I got it now. Thanks!

@mitu said in custom aspect ratio X & Y:

Care to elaborate more

raspberry pi 3 b+ and pi2scart from arcadeforge

@mitu said in Resolution/Video Mode/Aspect Ratio...:

Set your Pi to 1080p and then don't alter any configurations - you don't need to choose 1080p again in the launch menu.

This worked great, but....

I had to edit /boot/config.txt directly and tell it to ignore the resolution my tv was requesting.

This was the missing magic for your simple solution to work for me.

hdmi_ignore_edid=0xa5000080

You can also set the resolution in the same file.

Otherwise, regardless of how I set the right resolution something was wrong with either the desktop, console, or retropie.

@anothervenue

How did you come by your RetroPie setup? Did you personally install and configure everything?

@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.

@ironj679 Hmm. That seems rather suspect to me. The Pi needs the config.txt to know all of its boot settings. How did you build your software setup? Those details are a prerequisite for posting questions here anyway. You should be starting with the official download of the retropie image, and it definitely has a /boot/config.txt.

@dankcushions Got it. Thanks - appreciate the clarification. I think I was simply mistaken on what the proper AR should look like for those games. Although I think as a personal preference I like Mat Mania slightly wider (1:1).

Have you tried the overscan setting?

@telengard

Did you ever figure out how to set/unset the framebuffer settings after launching advmame?

Unfortunately no. I reported the issue back in April of this year, but unfortunately the same behavior still exists in the latest AdvanceMAME 3.9. Currently, I believe the only solution is to reboot RetroPie after AdvanceMAME has been launched during a session to reset the framebuffer.

Like any big project with limited contributors, bug reports known to affect more users are often prioritized. That being the case, it might help for those affected here to add a comment to the thread. Nothing pushy of course. Just a simple "same here" type statement would do the job.

Great knowing that they do. Thanks!
