I've seen some people take those Jakks Pacific Plug and Plays and put in real arcade buttons and joysticks, in order to make it more authentic.

I have a great Pac-Man plug and play, and I wanted to put it in a box with an 8-way joystick and restrictor plate, has anyone done something similar to this? It looks pretty simple, but the menu button on mine has a very strange setup that I'm not sure if it could be replaced with a regular button.
