lol thanks i reinstalled the thing cause i thought if i removed the configs for the emulators that would do it and obviously it didn't. I'll give that a go if I have the issue again I hope that won't give me the same issues.

@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.

Nevermind. I was able to test even though I'm away from it and I have an idea of how it works.

Thanks for the help.

@dankcushions Ok thanks. I will try your suggestion.

In order to conserve resources, I run my setup at 800x600 (hdmi_group=2 hdmi_mode=9).

I'm more fond of original aspect ratios so 720p/1080p is pointless for me. If I need to stretch the image to 16:9, I just use the telly/monitor menu.

@addison Try to disable the overscan settings - https://github.com/retropie/retropie-setup/wiki/Overscan

@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).

@redbatman yep, same difference.

need more info about your setup

@simonster I can try that, I'm tempted to just rebuild my retropie system and see if that fixes the problem since I've already sunk hours into troubleshooting this and could have rebuilt/restored everything in 1/10 the time :)

I would think if anything retropie running on OSMC would be slower since OSMC is still running in the background and using up CPU/Memory.

@retrocraze you may try to set the resolution you want (smaller than your tv native resolution) in the config.txt file and, in your tv video aspect options menu, set "original" or something similar, depending on your tv brand.

@dankcushions thanks for your help! totally fixed my problem!

@edmaul69 Games like OpenTTD and Duke Nukem 3D, listed as ports in the /home/retropie/roms folder, but only the obes you can download from the optional packages

@mattyl42 hook a keyboard up to the pi and press f4 in emulationstation. It will kick you to the commandline. Type:

sudo nano /boot/config.txt

After you make your changes press ctrl +x and then y to save.

you can change aspect ratio to 16:9 via https://retropie.org.uk/docs/Configuration-Editor/ - you can either do it for all libretro emulators (most of the emulators on retropie), or for individual ones.

this will stretch the original (typically 4:3) image, but if that's what you want...

Ok guys, I have just redone the SD card and it's working perfect - as far as I can see the config file is identical to what I had it as. I have no idea what happened there but to be honest, its now working and the kids are happy so all is well.

Thank you all for your help and suggestions.
