Would use some Arduino or Rasberry Pi to host the PS/2 keyboard and remap it there and then pass it along. Figure the usual boards and a code project. I've yet to see per keyboard mapping on Windows.

I have a ps/2 keyboard controller that was originally designed for an arcade system, however the software designed to reprogram the rom does not connect to it anymore. It functions well, but they keys are just locked to whatever they were last programmed to be. Sooooo, what I would like to do is to remap the PS/2 keyboard (it appears to windows as any standard keyboard) but NOT remap the USB keyboard that is also attached...otherwise it would be unusable.
Is there a way to accomplish this?
