A Mickey Mouse racing game made by Rare a few years after Diddy Kong Racing. An "all cups" TAS would be pretty neat I think.
Here's the RTA leaderboards:

The game has had a few new shortcuts discovered recently, which is pretty neat.
There's a debug code that you can input on the title screen (DpadRight, DpadUp, B, B, DpadUp, DpadLeft, B, Z). With it, you can view your X, Y, Z positions and your current angle. Probably wouldn't be allowed, so looking for these in RAM Watch or something would be the better alternative. There's also a cheat code that lets you see the checkpoint system in the game (only useful for testing stuff).
What is going to be a problem is making a verification movie that unlocks everything possible. Due to the progression system in this game, making an acceptable "All cups" TAS for the site would require it, since the process of unlocking the final circuit with the fastest characters available to reach the ending would take a really long time.
So, what needs to be done? Well...
- Unlocking the extra 2 circuits, Victory Vehicles and Frantic Finale. VV requires to beat the first 3 circuits in Professional difficulty. FF requires obtaining the secret 4 car parts hidden inside all previous 4 circuits.
- Unlocking Ludwig von Drake (he's the fastest for the vast majority of the tracks in the game). Unlocking this guy requires winning Frantic Finale on Professional difficulty with a Platinum Trophy.
- Unlocking Dewey. He is unlocked once you beat the first 3 tourneys on Amateur with a Gold/Platinum trophy.
- Unlocking Louie. He is unlocked once you beat the first 3 circuits on both Amateur and Intermediate with Gold/Platinum trophy.
- Unlocking Huey... oh boy this kid. Basically, you have to insert the Game Boy color version of Mickey's Speedway USA into an N64 Transfer Pak and he will be unlocked automatically. THANKFULLY, this is possible to do in BizHawk thanks to the Multi-disk Bundler tool. Is this able to be used in a movie file? I don't know. Probably, I hope it is. If it is it would be the fastest unlock in the game, and he is pretty good in this game.
Or well, you can just skip all that hassle by using the Japanese version, where you only need to get one Ghost Medal.
- Unlocking Mirror Mode only requires to beat all 5 circuits.
- The extra track, New Orleans is weird. To unlock this track, you must go to Practice Mode, go into the farm zone and look for chicken eggs, squash 20 of them and you hear a tune that means you've done it succesfully. Either that or get all 20 Platinum Trophies. I'm mentioning this just in case anyone wants to do Time Trials for this one track specifically.
- There's also a Digital Speedometer "cheat" that you can unlock by winning a Gold/Platinum Trophy on Mirrored Motor Way Mania. Useful for more easily measuring your top speed (if the exact RAM addresses and values aren't found.
Maybe I'm overthinking things, maybe you don't need to beat all cups on Amateur and Intermediate to unlock the final cutscene and ending. Maybe it doesn't even trigger again after doing everything. Perhaps you only have to play through Professional for the first 4 cups but leave the last one unbeaten for a verification file? I might have to ask around their Discord server for more info.
