Yoshito Yasuhara conveniently voices both Hol Horse and J. Geil (who work as partners), and Tsutomu Tareki voices Polnareff and Alessi (who face off in the manga).
Yuji Kishi voices N'Doul, Daniel J. Darby, Devo the Cursed, and Vanilla Icenote only in the original JoJo's Venture.
Assets for N'Doul suggest he was originally meant to be a playable character, as he has life-bar portraits that react to hitting or getting hit.
An alternate player 2 colour, a VS screen/super move cut in image, and a "New Challenger!" cut in.
Others include sprites for Enya Geil, Cameo and his Judgment Stand, and Gray Fly/Tower of Gray, suggesting they were either going to be playable or appear as minigame bosses (which they were in the PSX version).
There are also some unused vocals, one of which is Young Joseph saying Caesar's name at a much quieter volume, and Vanilla Ice ranting at Iggy for making him attack DIO's image.
Keep Circulating the Tapes: The arcades are extremely rare to find, and the Playstation and Dreamcast versions don't fare any better, costing at least $60. The Xbox Live and PSN versions (which are unedited and uncut) have been unavailable since the end of 2014 following the transfer of video game rights of the franchise from Capcom to Bandai Namco.
Market-Based Title: The original arcade game was renamed "JoJo's Venture" in America, while Heritage for the Future was just titled "JoJo's Bizarre Adventure". The XBLA remake simply calls it "JoJo's Bizarre Adventure: Heritage for the Future" universally.
N'Doul was originally going to be a playable character as he has a second player alternate colour, animated lifebar portraits, an image on the "Here comes a new challenger!" screen and super move portraits as well.
An unused sprite and life-bar portrait data in JJV suggest Hol Horse was originally going to debut in that game.
The same sketch also shows concepts for Alessi transformations, one of which appears to be young Phantom Blood-era Dio in boxing gear doing his thumb-in-eye punch, hinting that that would have been an Alessi form for either of the DIOs.
Facts
Much like in the manga, the Japanese version of the game prints DIO's name in English all-caps to reflect a change in what his name was paying tribute to (The band "DIO" that Ronnie James Dio himself formed.) The English version follows suit in the story text by always printing DIO's name in all-caps as well while other character names are still case-sensitive, hence why this game's article writes DIO in that fashion.
Quite a number of Midler's newly drawn images of this game were based off of Yukako Yamagishi from Part 4. Specifically, Midler's "super combo KO" cut-in appears to be based off of an image of a very angry Yukako from Volume 32, Chapter 302.
