The Adventures of Bayou Billy

From NES Hacker Wiki
Jump to: navigation, search

The Adventures of Bayou Billy is a multi-genre game that combines aspects of beat-em-up, shooting, and driving. You control Bayou Billy in his daring rescue of Annabelle, his girlfriend who has been kidnapped by an evil crime lord. The game suffers the same problems of most multi-genre games, it tries to do several games at once, but only succeeds half-way on each of them. Add to the fact that the play control is pretty awful and the game is also extremely difficult, and you get a game that couldn't live up to the hype. The original Japanese game is pretty hard, but it's actually easier than the North American release which is practically impossible.

This game is pretty dialogue happy for an action game. It has a three character sets. A limited one for the title screen, a full upper and lower for the dialogue in the cut scenes, and a smaller set with numbers for the menus and game play screens.

Texts are virtually the same that the American version but several letters or numbers due the differences between license advices, year of production and more.
