Williams Defender arcade. Clock 1 million, clock waves, pick up all 10 + a humanoid trick.

This is Williams Defender green label on MAME, factory settings. On wave 1 I pick up all ten and force 5 through to the top of the screen. This is a bug and I always wondered what happens as they start to crawl down the screen when they reach the bottom. Gary Whittingtham has done this and I wanted to do the same myself. You can see they eventually settle back on the mountain. I've clocked Defender many times but never taken the time to keep playing. I wanted to see the waves clock to 0 and get through the first half of the second million on the lives you get for every score after 990,000 and before 1m. I just about make it.
