There exists an unfinished TAS, which was somewhat hard to find, so I'm making a post here to make it more accessible to non-Japanese speakers.

I believe it has imperfect strategy, especially regarding not picking up the 2 Bomb cards from Bomber Wall, which makes the Phoenix fight 2 turns longer. Regardless it has interesting card pickups for Golem and Bebuzzu 2, which I want to look into. It's also interesting to see the limits of some minigames and battles.

It was originally posted on nicovideo in 3 parts:

A reupload that coalesces them into one on YouTube also exists:

PS.: I do plan to come back and get WR on this game, but the difficulty of Bomber Wall on emulator and the inaccessibility of DS capturing methods is making it tough :(

In boostin' with filmore and probably other races too you can save several seconds by driving off the track at a specific point to get reset ahead by the game. I would consider this an exploit ,not a bug and its not mentioned in the rules, but I still wanted to make sure if this is allowed to do in a glitchless run.
