I'm not sure how much the footage from Hackers counts, but at the same time I have no idea what stages Wipeout went through in development.
I was looking for my Okami strategy guide, I either misplaced it or put it with my multiple hundreds of gaming magazines from the last nearly 20 years. As I go through all these old magazines, I've gotten stuck looking at articles from different eras in games. Going through the mid 90s and seeing early PSX/Saturn/N64 titles, I stumbled across an early Wipeout shot. It got me wondering what early builds of the game looked like, so if anyone else happens to have early shots they could share, I'd be appreciative
