Anyone have plans or know of an adapter to use an NES pad on the PCE? The replacement controllers are getting expensive for it, and I've got a whole bunch of NES pads, plus the Max, some joysticks, etc.
I saw it. Fancy but also pricey. It shouldn't be that hard to put some resistors and maybe a shift register inline to take the NES signals and convert to the PCE. I found a project that converts the Genesis pad. I know the signals are different but something low cost should work, like an Arduino or something.
Have not tested the above so can't say whether it works for sure.
PCE 2-button controller schematic:
Tried to make this circuit minus the turbo functionality for a pad hack to an arcade stick (DB15 / NG standard) but did not succeed - connections / wiring all seemed fine so not really sure why it did not work but maybe you will have better luck.
