@mavica_again sure! I actually just made one to replace the one on the wiki
the more muted one is directly based on a hardware capture and is roughly true to how it ends up looking on a real CRT
the other one is contrast scaled to use for converting fullcolor artwork and preserving the total number of colors (along with relative color intent, hopefully)
@mavica_again here's how it comes out on TV! (it says press start because I just pasted it on the title screen file)
