I didn't quite like the first version that I made as much as I was hoping I would. Enter, PRIDE-6 v2. An updated design with some extra overlays for Gameboy Color and Gameboy micro. I've also included the PRIDE-6 v1 overlays, just in case you'd like to have that option, but if you like v1 more than v2, feel free to head on over to the v1 repository.
Included are Gameboy Advance SP and Gameboy Color overlays with normal and holo-style bezels, with and without grids, with the necessary configuration files. Credit to AntiKK for allowing me to edit his overlays and use his config files because I can't code to save my life.
NOTE: You can put these wherever you want, really so long as you can navigate to them and they aren't in any vital system folders. I'm just recommending the ideal location for them with the other overlays.
