Having just recently taken up speed running I ran into a bit of a problem with my front loader NES. If I would too quickly hit either the power or reset buttons I could hit the jossel the unit just enough that it would disrupt the cartridge inside screwing up my whole run. I became inspired.

In this photo you can see that I've added a silver power switch to my controller on its upper left corner, and a reset button near the top center. I've modified a network jack to allow me to plug those buttons into the NES. Originally I was working with a USB port but when it came time to glue things into place it just wasn't working.

Hopefully no one tries to plug an actual network cable into this machine, I'm really not sure how that equipment would deal with 12 volts over its data bus.
