Magical Hat Turbo no Buttobi Tabo! Daibōken was released in 1990. But when SEGA of America got their hands on it, they changed a lot of things around and released it as Decap Attack in 1991.

From the intros. Pink dog thing gets replaced with a green skinned monster, old guy gets replaced with a mad scientist and the big bad guy has a different sprite, with changes in skin colour along with different armour.

Different option screens, Decap Attack lets you set how many hit-points you have rather than lives.

These screens are shown before a level starts. Magical Hat doesn't bother telling you the name of the level you are about to go on.

This is what the starting point of the first level looks like in each game. The gameplay is the same, but the graphics and music are totally different. Magical Hat does not have hit points (as in one hit and you die) whilst Decap Attack does.
