Yes I see,but most people don't have more than a 3 button MP4.
My MP4 is a Rockchip 2.8in Touch screen which might actually be able to play NES,Genesis,GBC,
Because it has three buttons on the bottom and if someone could impliment a code for touch screen movement it would,
allow for D-pad movement with the Touch screen and use the bottom buttons for A/B and maybe start.
I wouldn't want to stop someone from the idea,by all means go ahead,I think it would be a great idea,and a great learning experience.
Im just saying it probably wouldn't work for most people
BTW you've got a really nice player.
