I would like to turn my NES classic and snes classic into portables. I seen alot of portable DVD players on Ebay with hdmi. Could these be used for the screen? Would love to hear suggestion on how to split up the buttons and control pad to each side of a housing. Also has anyone found a power supply that will allow for charging while the snes classic or nes classic is being played on. If anyone has pictures or a like to a build of these, I would greatly appreciate it.
