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.

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 :(
thanks for the answers! Unless anyone tells me not to ill use this in my next runs!
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.
