This is a custom Retroarch overlay for the Sega Game Gear. I made it by merging these overlays:
-OrionAngel's Game Gear Overlay (Used texture for screen glare)
-flatuswalrus's Better/Fixed Game Gear Overlay (Used most of console)
-Images of a master system background and game gear logo I found on google
Included are four versions, so you can pick between having logos and a glass screen. I also included the source pictures, if anyone wants to modify it in the future.
And yes, I know the screen is off center. It bugs me a bit too, but I'm not skilled enough at photo editing to fix it.
