Jester [MD/G – Cancelled]

Jester is a cancelled platform game that was in development by Sega of America for the Genesis / Mega Drive. There is not much info on its gameplay and only few levels backgrounds are preserved in the gallery below. Jester was canned after a problematic development and it is unknown how much was completed before the cancellation.

Thanks to Alan for the help in preserving some media from this lost project!

Thanks to Jason for the english corrections!


Cybernauts (DNAction): The New Breed [SNES GEN MD – Cancelled]

DNAction: The New Breed (AKA Cybernauts: The Next Breed) is a cancelled fighting game that was in development for the Super Nintendo and Genesis / Mega Drive that would have been published by Accolade, Inc. in 1994. Accolade made its name in the late 80’s and early 90s with franchise’s such as Test Drive, Hardball, and Bubsy but started losing steam around the mid 90’s which caused the company to want to shift focus and reinvent itself. It is possible that this change of direction in the mid 90’s was the cause for some games to be cancelled in development such as DNAction. Accolade was also purchased by Infrogames in 1999 so any hope of the game being revisited seems to have ended there.

Although The game was never released, some info about the project and various character renders were found in old gaming magazines as Games World #1, Banzzai #21 and GamePro #56,  plus some  in-game screens from an early prototype found in Player One #43. DNAction used pre-rendered sprites for characters and backgrounds, created with Silicon Graphics in the same way as Killer Instinct.

The game was to be placed in a future setting with scientists being able to genetically enhance humans to create their own superheroes. Some, however decide to use their powers for evil thus pitting a rivalry between those who received super powers. There were at least four planned playable characters: Pitbull and Hotshot who were members of Matrix Alpha, the superheroes trying to help society. Then the two members of the evil organization Overlord: Ground Zero and Tracer. An additional 4 characters were shown, Shockwave and Banzai (Overlord) then Recoil and IronClad (Matrix Alpha).

Thanks to Celine and Rod_Wod for the contributions!

Zero Tolerance [Beta – Mega Drive / Genesis]

Zero Tolerance is a FPS developed in 1993 / 1994 by Technopop and published by Accolade in 1994 for the Sega Mega Drive / Genesis. Zero Tolerance was a unique game in that there weren’t many FPS console games back then. Just like other Accolade games, Zero Tolerance came in a unique Accolade game cartridge. Zero Tolerance also supports a link cable where two Genesis systems can connect and play in the same game.

Let’s begin with a look at this image:

Sero Tolerance Beta

Here we have two beta / prototype cartridges, and a final copy of Zero Tolerance. I’ve gone through the early prototype and compiled as much beta material as I could find.

Differences between the final and beta / prototype versions are:

  • -There’s no music in the prototype. Sound effects are still present.
  • -Nearly all the logo’s at startup have been slightly changed.
  • -The options menu in the prototype has significantly less options.
  • -The characters between games are completely different.
  • -In the proto, you do not start with a weapon.
  • -There’s no text at the top of the screen when the map is displayed.
  • -The counter on the left, which tells you how many enemies remain on the level, is not functioning in the prototype.
  • -The name of each weapon and it’s number of bullets remaining, have swaped places.
  • -Some of the text on the wall is a different colour.
  • -The image on some doors is different.
  • -The robots on the High Rise Roof make a different sound.
  • -In the proto, when picking up a weapon it just says “WEAPON COLLECTED…” instead of the weapons name.

Technopop has released Zero Tolerance as freeware. This means you can download the Zero Tolerance Genesis rom legally and for free. A sequel, Beyond Zero Tolerance (or Zero Tolerance 2) was also in development by Technopop, but it was never finished.

Megalol noticed that in Sega Power magazine from september 1994 the screenshots in the game’s review are actually from a beta version. Infact, you can notice a couple of small differences in the HUD (name of the weapons in different place, ID card) and Level textures.

Pulseman [MD GEN – Beta]

Pulseman is a side-scrolling action platform game developed by Game Freak and published by Sega for the Mega Drive / Genesis in 1994. The game was released in cartridge format only in Japan, with the North American version being released via the Sega Channel as an “exclusive”. When first announced, Pulseman was originally named Spark.

Derboo found a screen of the beta Spark  from the Korean gaming magazine, Game World #5 (1994). The on-screen display changed, and the screenshot shows a boss from the game with a slightly different sprite in a totally different situation.

The palette is also different, but the article also shows artworks with the characters colored just like in the final game, so it was probably just the prototype palette for the underwater effect.

Thanks to derboo for the contribution!

Smaartvark [GEN MD – Cancelled]

Smaartvark (also know as “Arnie the Aardvark” and “Miniature Aardvark TV Repairmen”) is a cancelled platform / action game that was in development by Codemasters for the Genesis / Mega Drive. The title is a wordplay between “aardwark”, a medium-sized mammal native to Africa, and “smart”: infact the main protagonist of the game was an aardwark TV technician, as we can see from its sprite in the screens below.

There are not much info about this project and we dont know why it was never released. It seems that the player had to repair a TV by entering in its channels and defeating the bugs that cause the problem.

Thanks to Rod_Wod and Celine for the scans!
