catbox really is doing god's work, when they work, and until they get nuked for CP/bad actors uploading bad shit expressly to get it nuked. Fuck it here's a megaup link. They tend to last forever, just make sure your adblocking's good.

These are presets I use for GB, GBC, and GBA. Place these in retroarch/shaders. Interframe blending set to simple (core setting in MGBA and Gambatte, not a shader) can make a lot of difference in games like Castlevania II - Belmont's Revenge. The cloud castle backdrop will display in a lighter shade instead of flickering, which was the trick they pulled off to get extra colors thanks to the GB's slow pixel response. You can set pixel response in the shaders too, but I find it much more invasive and distracting than the core's interframe blending.
