Okay, so after I familiarise myself with the control of the DS version of the game, I think it's time for the next part, the routing. For this, I mainly focused on the first level, which is Skatepark. The rest of the level I may cover about later.

So, the goal for this map are as follows:

1. High Score - 25,000
2. Pro Score - 50,000
3. Sick Combo - 150,000
4. Pro Combo Score - 5,000
5. Sick Combo Score - 15,000
6. Collect S-K-A-T-E
7. Collect C-O-M-B-O
8. Nosegrind (Up + X) the Dozer Blade
9. Spine Transfer (R) The Pools
10. Find the Secret Tape.

The C-O-M-B-O letter is located along the right side of the train track, which is near the spawn point. The S-K-A-T-E letter is located outside of the warehouse, near a halfpipe with ramps on both sides align together. The Dozer Blades can be found right next to the crane. The Pools is literally right next to the player when spawning on the far side of the quadra-pipe. The Secret Tape can be found in the area where the tutorial for spine transfer a bit higher.

Here are the moves with its respective button presses and its points without the combo: (Y + Up) - Impossible - 100 points (Y + Down) - 360 Shove It - 100 points (Y + Right) - Heelflip - 100 points (Y + Left) - Kickflip - 100 points (A + Up) - Nosegrab - 300 points (A + Down) - Tailgrab - 300 points (A + Right) - Indy - 300 points (A + Left) - Melon - 300 points (Y + Up + Right) - Inward Heelflip - 350 points (Y + Up + Left) - Hardflip - 360 points (Y + Down + Right) - Varial Heelflip - 300 points (Y + Down + Left) - Varial Kickflip - 300 points (A + Up + Right) - Madonna - 300 points (A + Up + Left) - Japan - 420 points (A + Down + Right) - Airwalk - 450 points (A + Down + Left) - Benihana - 360 points (Up + Up + A) - 360 Sal Flip - 700 points (Down + Down + A) - Ollie North - 600 points (Up + Up + Y) - Kickflip to Indy - 900 points (Down + Down + Y) - Hellflip Varial Lein - 900 points

So, where do I begin?

Okay, now I made a route for this level. It's not perfect, but it is a starting point https://www.reddit.com/r/speedrun/comments/iyyaw2/skatepark_classic_mode_route_idea_tony_hawks/
