It's unfortunate that so much of this specific content is locked up as video. The part is $35 shipped on AliExpress, a great way to begin experimenting.

Unedited video is the fastest kind of content to produce, and the slowest to consume.

I have a much easier time digesting information​ at my own pace.

I prefer this video, showing someone playing Wipeout: https://www.youtube.com/watch?v=PH0wAmMbFgI#t=1m37s
