The Garibaldi track was still clearly WIP by that point. (Interestingly, the data for the demo release was compiled only around a month before the final game's release)
2 of the "ice pipe" shortcuts are technically there, but they hadn't modeled the entrances to them yet. So you have to drive into a collisionless rock wall to enter them.
the long shortcut with the jumps across the River lacks the ice on the uphill section at the end. You can see it in my video but it's rather in the background if you missed it.
There's also a part where either the hitbox for a billboard is way oversized or (more likely) theres collision for fences but no model for those yet.
Snowdream has entirely different rail textures for showoff mode. They are far thicker and sort of "metal" looking. I think they probably wanted to make the rails more noticeable so decided on the ketchup/mayonaise rails instead for the final game.
Since Snowdream and Garibaldi are the only tracks featured in the demo, theres unfortunately no way to see if there had been any other differences on other tracks.
By going through the games data there is one thing I noticed though:
- The demo tracks lack 3 linked sound files/banks. 2 labeled "construction" and 1 labeled "Ufo". So I think the mercury city UFO was either a late addition or it originally had no sound effect. Same with the construction sites.
Some other things of interest:
- It looks like the game was originally going to feature the regular "Space Raiders - Song For Dot" track just like SSX. Because in the beta files, the listed BPM is much lower. If you use the beta BPM setting in the final game, the "It's tricky" jingle is way to slow and goes out of sync.
- Slayboarder is listed as "Slayrmx" in the beta files and I think it also has a different BPM setting. Maybe there was a different version that got scrapped ?
I think there was a third track where the BPM didn't match. Probably one of the Rasmus tracks that got remixed for tricky.
