I'm getting some major visual glitching when using Crimson Eye. From what I can tell, it only shows up when you have Frame Skip set to 0 in VBA (60FPS), which is why the youtube video accompanying it makes it look perfect because it's in 30FPS.
Glitching of this manner appear on every other frame when playing at 60FPS. I don't exactly know how this would be fixed but I wanted to bring it to your attention in hopes that it can be fixed. I really want to use it because it's really well ported but not when it's this glitchy.
