I love this thread! I have a Williams Bonanza and a CCM Twin Rifle. I had to fabricate parts to get both of them working. Bonanza works 100%. The Twin Rifle works except for the electronic gun sound. If anyone can send me a schematic of the sound board I would appreciate it. The Bonanza is the best gun game I have played or seen. I really enjoy it. The Twin Rifle is very fun also with 2 people but not as fun when shooting alone. The hardest part was replacing a missing gun stock on the Twin Rifle. Finding a gun stock from a real gun and doing a lot of drilling/cutting and wood filler to get the stock to work with the game was a lot of work to make sure I got all the holes right and everything perfect. The Bonanza uses a 4 track tape player instead of an 8 track player. It needed a little work to get it working but it works great. Here are the pics.
