I am making Retroarch Overlays sized to fit 3DS starting with Game Gear. Also some Retroarch Menu Themes. Instructions and templates included.

They are in the Retroarch Overlays Folder with a template to make game specific overlays.

Megadrive is for 1x resolution of 320x224 which you might have to set. The core config had it full + wide screen on my 3DS.

Turbo Duo is 256x224. I don't use that core so I don't know what the default is.

Those are really nice. I liked the work you did on the MegaDrive and TurboCD overlays. But two issues (i) they did not include .cfg files, which I think are necessary to load them and (ii) they did not fit the resolutions using integer scale and Core Default Aspect Ratio. Creating CFG files is no big deal, but I had to tweak the overlays to fit. Please find my revisions attached.

Yeah I couldn't test it since I don't use that core. I looked at what the resolution was on the original and fit that according to how it would theoretically space itself in the 400x240. Also why I didn't have a config for it.

What was the custom video scaling you used?
