Thing that happen....that is giving a new thing for us all. Fix old projects toss old projects and start something secretly new.

Thanks credit to your video and amazing sounds of chimes.

I love the twist in Act 2! Totally did not see that coming.

Regarding the ground prong: It's possible they didn't cut it off at all. If the game was plugged and unplugged a lot, it's plausible that the prong just broke off from metal fatigue. I've seen it happen, especially on machines that used to be owned by a vending company, or machines owned by a travelling carnival, because those were regularly moved from site to site and thus were plugged and unplugged more frequently. But if the ground prong _was_ cut off, there are two reasons I can think of. The first reason is the most obvious: Maybe they only had two-prong outlets.
The second reason would be to eliminate a ground loop hum. In layman's terms, a ground loop is caused when a circuit is connected to ground at two or more points. Because the potential of the ground varies from point to point, two or more connections to ground cause currents to flow. Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. (I don't think you'd get ground loop hum on a pinball machine that still uses chimes, but I could be wrong.)
A good example of ground loop hum would be cable TV. Even if all of the audio and video equipment in a home theatre system is plugged into the same power outlet, and thus all share the same ground, the coaxial cable entering the TV is sometimes grounded by the cable company to a different point than that of the house's electrical ground. This creates a ground loop, and causes a hum in the system's speakers. Cutting the ground prong solves _that_ problem, but you're making your equipment less safe.

Great game room. How about a game room tour video or collection video.

That is awesome! Did you see the NBA Jam arcade thing they made? They also made a TMNT one. I want to get the NBA Jam one
