This game was released in North America as Dragon Power, and a whole hell of a lot of stuff was changed. Like, instead of running around beating up stuff as Goku, you run around beating up stuff as this weird little monkey thing. And of course, a weird little monkey thing was considered MUCH more acceptable for North American audiences. Anyway yeah, that's pretty much the game. You run around beating up stuff. As Goku. And there's lots of cutscenes interspersed throughout the game which gives it an illusion of plot. Despite it being Dragon Ball, it's a pretty fun little game, if you like those sort of odd Famicom games.

This patch reverts the original mapper of the game to MHROM.
The translation by TransBRC used the mapper 34 hacks as base.
