Latest RetroPie release has video issues

@mitu None whatsoever. This is just vanilla install with nothing done to it. All I'm doing is commenting / uncommenting the display rotation.

That looks like a problem with the firmware on the RPI. You can try to see if the problem goes away with either of:

using an older RP version - 4.4 (https://retropie.org.uk/2018/04/retropie-4-4-is-released/). Flash it, then use the same config and ROM to see if the problem persists.
upgrading your current system with sudo raspi-update to the latest kernel and firmware for Raspbian.

I get a command not found for sudo raspi-update when I hit F4

Sorry for the typo - it's sudo rpi-update.

@mitu I did the update first. After reboot, my buttons were reconfigured for me but the same problem persisted.

I then found a 4.4 image from archive.org and flashed it with Etcher.
Set up wifi
Copied just outrun.zip to the ROM folder and restarted ES
Still washed out colors
Replaced HDMI cable
Same thing.

I remember i changed the default brightness and gamma on mame2003-plus a while back it was for too high. It was originally changed because some people mentioned it was too dark in some games but made others too bright. So i restored the default mame078 settings to mame. Im pretty sure mark filtered these through to mame2003. First thing you should do is make sure you mame 2003 is updated to the latest version via the retropie setup script. Then make sure the gamma and brightness are set to 1.0 in the quick menu-> options.

ps i think outrun looks like it should with a gamma of 0.5 thats my personal taste though

I took the initiative to install Raspbian Stretch along with the latest current release of RetroArch v1.8.1 and it's doing the exact same thing. So my claim of RetroPie having video issues was incorrect. It's a Pi / RetroArch thing. I'll play with the gamma and see if it makes a difference. Kinda sucks that I can't get a 33-year-old game to reproduce video properly on the Pi. I might just use this thing for another purpose altogether.

You could try advmame instead of RetroArch and see if it fares differently, or don't use rotation in the OS and instead rotate Emulationstation and images only.

I don't have my pi3b+ set up right now to test, so I used my pi4 with raspbian buster with retropie pi4 branch repo. Retroarch 1.8.1 installed from cmitu's repo.
PC is using the same retroarch version, same tv, same tv picture settings, no shaders, no bilinear filtering. GPU is set to 32bit color depth, 8bit output color depth, RGB, Output dynamic range set to full. Fb-neo. Hdmi. Pi does seem to be a tiny bit brighter if you look at the road.

Turning down the gamma to "0.5" has made a remarkable difference. What a strange default option in RetroArch! Thanks to everyone who threw in their $.02
