Pretty simple but very usable. It has all 28 bars! unlike some games (def not lego man), also completely stamps! NES palette aswell. This is PEN!!! to use this your game's tiles and background should be rendered with pen (i don't know why you wouldn't, pen rendering is just easier to manage, less sprites and clones as well)
Capcom - Mega Man and musics Polygon games - Gaming @NMario84 for the epic NES palette color effect and brightness values
