I was setting up to make a TAS of this game, just to see if it exposed anything useful for regular runs, and while I was getting memory addresses for the main parts of the game I found a weird bug.

If the memory address for player health is frozen at a value below 4 and there are no lives left, you respawn one level later when you are hit. Video evidence:

With this you only really have to fight the megazords and rush to be killed by the nearest enemy so I was able to do a rough TAS that was sub 8. I thought this would be cool as a category so I made it into a codebreaker cheat code so it's easier to use.

Cheat code: 3300268C 0001

Looks like an interesting idea. Would run it as a laugh if it was accepted.

so in reality this is just a quicker paced boss rush

Pretty much yeah
