Wonderful work! I used a couple of these in place of my current overlays!
I have a request that might be easy for you. There doesn't seem to be a great Vertical Lynx overlay. Any way you could make one since you already have the source material for lynx? Thanks!
@mitu Thanks for the links, I'll have a look and try to figure it out. I don't think it's shaders though as when I go into that menu for either it doesn't say any shaders are set and when I enable one I get serious lag issues. The only difference I could see was the colour palette was different. But when I change that to be the same I only get a very slight green tinge. So I'm a bit stuck on what's causing that 😅
@supercatfooz You can choose what image to show as splashscreen through the RunCommand options - https://retropie.org.uk/docs/Runcommand/.
It is possible to copy your own image in the emulator's config folder and have it display when launching a game (for that emulator). See the section about Adding custom launching images in the doc page above.
