The controller of the original Nintendo Entertainment System is a classic, but it may not be known for its good ergonomic principles. In any case, using it for a long time can become awkward. To help alleviate this situation, [Taylor] A simple way to convert the NES controller to left-handed operation is proposed.
The key to cracking is simple. The buttons of the controller are swapped from left to right, so that the controller can be inverted. In this direction, use the arrow keys with the right hand and the operation buttons with the left hand-the opposite of the usual way. Therefore, the left and right and A and B on the D-pad must be switched, so all the controls are in a logical layout.
This is achieved by using a small mod board [Taylor]Own design. The original HD14021BP chip is removed from the PCB of the controller and installed on the module board. The module board can then be soldered back to the controller and rewired to swap buttons.There is also a version [Taylor] Thanks to some on-board DIP switches, the design can be switched between right-hand and left-hand operation.
This is a neat hack that can save the thumbs of some dedicated Tetris players. Or, you can always make your own NES controller from scratch. Video after the break.
