The Adventures of Bayou Billy is a TRIPLE HARD ACTION GAME starring a Crocodile Dundee-wannabee who must save his Daisy Dukes-wearing girlfriend from a New Orleans mobster. It features beat-'em-up, gun shooting (with optional Zapper support) and vehicular combat stages in an attempt to mix-in a bit of every arcade genre that was popular at the time. It's best remembered for its funky theme music and somewhat absurd difficulty level. Watch the crocs!

Regional Differences OH GOD

Unused Graphics

A frame of Annabelle leaning in to kiss Billy intended for the ending sequence. In the actual game she just closes her eyes as Billy approaches her and it cuts to both of them already making out.

Unused Text

Version	Offset	Text
Mad City	0x17AD0	ダン グールド
The Adventures of Bayou Billy	0x16283	DAN GOULD

A name that is unused in both versions of the game. It appears among the names for all the enemy characters listed during the ending cast roll. This was likely the name intended for the Diver Man/Frogman enemy character, who is simply credited as Diver Man in the Japanese version, the same text string used for his role, presumably a mistake due to a coding oversight. The Frogman enemy was renamed "Jacque Killstow" in the English version, which uses an additional text string that was added to the game's code at offset 0x166B2 right after Michael Maezawa's name.

Version	Offset	Text
Mad City	0x17D22	ニュー　オリンズ
The Adventures of Bayou Billy	0x1652B	NEW ORINZU

This string appears among the text used for the ending staff roll, between "TITLE DESIGN" and "Mt. FUJIO" (DAMIAN FUJIO in the Japanese version). New Orinzu is, of course, a reference to the city of New Orleans where the game takes place, although this was more likely intended to be a nickname for someone in the game's staff than an actual acknowledgement of the city.

Version	Offset	Text
Mad City	0x17BB0	キャスト
The Adventures of Bayou Billy	0x163FC	KI UTO

キャスト means "cast". This text string was likely meant to appear just before the ending cast roll, but in the final game it just goes straight to showing the names of the characters without any setup. The English version of the ROM just replaces it with semi-gibberish (it almost looks like it was going to be transliterated as "kiasuto" until someone realized that it was going to be unused text anyway).

Version	Offset	Text
Mad City	0x13DF0	NEW ORLEANS
The Adventures of Bayou Billy	0x13C08	new orleans

Another unused text string referencing New Orleans, this appears just before the text string that spells out the game's title that is used just before the opening cutscene. Presumably this was meant to be setup text or even a working title for the game. In the English ROM, the text appears entirely in lowercase letters due to how its different character set are arranged.

Curiously, the instructions which tells the player which input device to use on each stage can be found in the Japanese ROM at offsets 0x13D4B (for the regular controller) and 0x13D71 (for the Zapper), even though they were not used in Mad City.
