I wanted to design a simple hardware that could be assembled on a prototyping board. Except from the blue pill board it use only 2 IC. One 74HC84 quad xor gate used to invert chroma signal phase. There is a 8 buttons gamepad that use one 74HC164 shift register. All other components are passives. 

here a demo of the console in action. It support SCHIP mode + my personnal BPCHIP mode.
