World Heroes

Posted: by Frank Gasking

1994 Working Designs / SNK

Platform: PC Engine

In the early 1990s, World Heroes (a popular Neo Geo fighting game developed by ADK and SNK) was being ported to the PC Engine Super CD-ROM by Working Designs. Known for their quality localisations and close collaborations with Japanese developers, Working Designs were said to have had a good working relationship with SNK, which included this unreleased port.

WorldHeroes

According to direct conversations with one of the Shirley brothers at Working Designs (likely Don Shirley), the PC Engine version of World Heroes was reportedly fully complete. The port was being developed with direct involvement from the original Neo Geo development team, ensuring arcade-accurate gameplay and visuals within the limits of NEC’s hardware. Continue reading →

Splitz Game Boy prototypes

Posted: by Frank Gasking

I loved Split Personalities on the Commodore 64, and I was massively surprised to learn that a Game Boy version was produced in later years called Splitz. It had completely passed me by, and I first discovered the game when finding a series of prototypes in relation to the title.

The game works incredibly well on the platform, so if you haven’t played it before – I recommend checking it out. In the meantime, we have a series of prototypes of the game from various stages of development, and thankfully with dates for most. Continue reading →

Micro Machines 1 and 2 Twin Turbo GBC prototypes

Posted: by Frank Gasking

More prototypes added to the Games That Weren’t archive, where today we’re adding a series of Micro Machines 1 and 2 Twin Turbo prototypes for the Nintendo Color Game Boy. These all vary a lot, though we were unable to attribute accurate dates for all of them.

mm screen large

MM2DEMO.gbc is one of the most interesting, as this seems to be a very early iteration where the Game Boy original game was being converted over and re-colourized. The music map is quite glitchy and the sprites are not yet reworked, but you can have a race and even see remains of the original title. There is likely more tucked away, though we think just the one level has been re-done. Continue reading →

Trax

1993 Enigma Variations

Platform: Nintendo Gameboy

Our next entry into the archives is a very brief racing car game development that was being done by Roo Bowen for Enigma Variations back in 1993, and may have been based off their work for Nigel Mansell’s Grand Prix for the Commodore 64.

trax large

This is an extremely early prototype for a first person perspective racing game and a neat track routine which you can accelerate and brake and move around a bit – but nothing else at this stage. It is possible that the prototype was just produced as a proof of concept and not taken any further. There is no evidence that a proper game was under way. Continue reading →

ShockWave

Posted: by Frank Gasking

1991 Digital Magic Software

Platform: SEGA Mega Drive

Described as a sort of strategic Space Harrier game, ShockWave sent enough shockwaves to impress magazines of the day for the Amiga, but did you know that a SEGA Mega Drive edition was later on the cards in 1991?

Thanks to an article with Digital Magic Software in June 1991 (published July 1991 in Games X magazine), they reveal that the group were bringing in equipment to do Mega Drive games, and Shockwave was being lined up as the first title. Continue reading →

The Addams Family: Pugsley’s Scavenger Hunt (Gameboy) Prototypes

Posted: by Frank Gasking

Following on from the NES Pugsley’s Scavenger Hunt prototypes, we bring you two more this time for the Nintendo Gameboy. One is dated from the 22nd April 1993, though the other prototype is unknown – but we believe it is slightly earlier.

When comparing the April build, there doesn’t seem to be any noticeable differences compared to the final retail version apart from the header. We have very likely missed something, so if anyone spots anything different between the April edition and the final retail version, please let us know. There are noticeable differences in the code – but we’re not quite sure what they are without more in-depth digging. Continue reading →

Croc (Gameboy Color) prototypes

Posted: , last updated: by Frank Gasking

Today we are bringing you a very early test build of Croc on the Colour Gameboy which is of part of the first level map, but with a lot of content and presentation missing at this stage and no enemies or collectables. Score panel isn’t finished and contains junk characters.

croc large

Here you can move Croc around the slopes and up on the platforms, before hitting a dead-end. However, if you keep pausing and unpausing whilst jumping, I found that you will essentially “jump climb” up past the dead-end to be able to see a bit more of the map. Continue reading →

Posted: by Frank Gasking

Our sixth update of the year for our ever-growing Commodore 64 archive is mostly updates this month, with 3 new entries, including Dominion (a long lost shooter), details about a Stephen Hendry snooker game from Zeppelin that fell through and a rather risqué adventure game which many feel could have been a fake.

All finished off with 16 updates with various new scans and also new updated screenshots for the Mega Games entry after the recent better quality BBC Commercial Breaks upload, and news of an Alien 3 prototype. Oh, and keep an eye out on the site tomorrow! ;)

Dominion – a full shoot-em-up recovered!
