Never saw the point of the other speeder footage - just too long to award a bonus. This seems to be better.
Star Wars was rushed out at the time, and some "unfinished" or unpolished features were effectively left out, by simply bypassing them or not calling them in the code.
If you are familiar with the full background of the 20th anniversary code project, it started when after several years, someone accidentally found the Ballsave "Freeze" feature when they were cleaning the game, pulled a ball out of the shooter and put it in the trough, and the game responded by kicking it back out and doing the Ball Save thing. Due to unfinished code, the ball save was being dfissabled by the first switch the ball hit (in the shooter lane) so no one had ever seen it before, fixing this was the first goal.
During the project, they also found undocumented combo shots that either didnt work or were near impossible to achive, so these were also made playable in the 20th anniversary code.
The guy working on the code also stated that the videomode was in there, but bypassed as it was unfinished, hence why you see that start of the videomode, but it doesn't actually do anything, it has been known for some time, that there should have been a video mode that was never finished, all they did was jump the code to the end where it awards the 10 million to get around it being unfinished in time for release.
