Go to a hardware store/ lumber yard and buy some wood. Go to the BST forum here and buy however many sticks and buttons you want and an encoder of some kind (or take your xarcade apart and use that encoder, but beware, there grounds are not common). Go to an electronics place and get some 22 gauge wire and a soldering iron or some quick disconnects. A wire stipper will be helpful, but you could just use a pocket knife if you want. If using happ parts you will need a 1 1/8" spade bit. You will need a drill and a saw with the appropriate blades. cut the wood into your desired shape for the top panel and drill the needed holes wherever you want them. If your feeling frisky cut some more strips of wood for the bottom support of your panel. Glue those in place. Cut the wire to length and wire the buttons and sticks to the encoder. Plug the encoder into your pc and load up mame. Play all the Thunder Jaws and Survival Arts you can stomach.
