This effect maps all the colors of your objects to perfectly match Gameboy 4 green colors. Can be added to any object but gives a better result if you add it as a layout effect.
is there a c2 version too ?
the latest version of the effect and its C2 addon is published now and available for purchase in the following link.
it actually works on both, Effects are compatible. I'm also about to release a tweakable version of the plugin on itch.io soon, together with some additional effects.
