Interesting bootleg NES version of smw. Pretty much all the effort went into getting yoshi working on the nes as everything else is pretty bad. This game has an annoying combo of mario accelerating way too fast and enemies loading in really late, any time you jump you lose all your speed which makes jumping really annoying and the music ranges from OK to terrible. There are some cool things that I'm surprised they were able to get working on the nes. Honestly if Mario's movement wasn't so bad this game would have been decent.
Annoyingly the rom I downloaded ended the game halfway through despite a full game version existing so I might come back to it at some point.
