- This all starts from mapping what contacts go to what keys on the USB keyboard. I decided to use the minimum number of wires and just remap the keys in the emulator. So I went with 2 columns (pins) and 7 rows (pins) , so it's 9 solder points for all 8 buttons.
- Chopped as much of the nes controller as I can to make room for all the new components. While making sure not to disturb the plastic supports. As to not to change the feel of the button presses.
- Removed the USB hub and USB flash drives from there plastic enclosures. And soldered everything together.
- Downloaded an Emulator and some ROMs and put them all on the USB Flash. I'm thinking of adding an autorun.inf/autoplay that well launch the emulator when the nes controller is plugged in.
That's it a quick weekend build... about 3-4 hr.
