The title of this game translates from Japanese as 'Mister Pig'.
An English version was also found, although the English version still shows a "For Japan Only" warning all text was translated into English. The title was changed to "Pig's & Bomber's" in the English version although the title screen still shows Butasan (in Japanese) above it.
