[QUOTE=hunterk;18174]Since you’re on Wii, I assume you’re running at 480p, so you would make your overlay image with dimensions of 720x480. If you’re using 4:3 aspect ratio (I think that’s the core-specified aspect for NES, SNES and Genesis), you would leave a transparent box 640x480 in the middle and put logos or whatever in the remaining 40 pixels on either side.
You can put the files anywhere you have access to, presumably on your SD card in the RetroArch directory. The cfg files are very simple for borders (like 2 lines) and you can just copy any of the existing borders’ cfg file and just change the file reference therein to match your overlay image.[/QUOTE]
Yes. Well, actually I’m running it on vWii (Virtual Wii on WiiU) And I ASSUME it’s running in 480p upscaled to 1080p on the WiiU itself. I THINK Wii’s widescreen resolution is more like 854x480… Do I still have to make the overlay 720x480? And one last question: What about Gameboy, gameboy advance and Game Gear? Do you happen to know their resolutions? Thanks for all the help.
