I recently played through the awesome retro-styled platformer Shovel Knight for the first time and, while the pixel art is incredible, I kept thinking "I bet this would look even more amazing on a CRT." The game runs at a higher resolution on PC, so getting the low-res scanline-y look I crave wouldn't really be possible (or at least would be a significant hassle) through a 31 khz PC monitor. However, thanks to j_selby's out-of-the-blue Citra-libretro core, we can now run 3DS games via RetroArch--including Shovel Knight--and apply all sorts of fun shaders to the output!
