Software Releases

EA Classics

EA Classics is a combined single cartridge release of the 1st three of my games written completely in machine code that were released for the original Spectravideo and MSX machines in the mid-80's.

So far it is available for the Colecovision, but I will be releasing it for both the original Spectravideo and MSX computers in cartridge form shortly.

Pyxidis

Pyxidis is a vertically scrolling shoot em up game released for the original Spectravideo and MSX computers in 1985.

A release is planned on cartridge for the Colecovision, followed by re-releases for the original Spectravideo and MSX computers.

Seaquest 99

Seaquest for the Atari 2600 was one of my favourite games back in the day, and a game that should have been brought out for other systems. 

So Seaquest 99 is a TI-99xx version of the game i.e. it will run on Colecovision, original Spectravideo and MSX machines.

Cavern Fighter

Cavern Fighter was an unreleased game of mine from around 1986, I finally completed it in late 2020 for the Colecovision and I am in the process of back porting it so it can run on the MSX and original Spectravideo.

It is a take on the arcade game Scramble that I used to love playing when I was younger.

You can watch a video of the Colecovision version here.

MSX/Coleco Sprite & Tile Set Editor

This is an application written in C# .Net for home brew developers to create both Sprite and Tile Set designs for their home brew projects.

The sprite design section allows:

• multi-layer pattern design
• animation sequences
• export to assembler and C formats
• import data directly from existing source code

The tile set editor section allows:

• characters can be designed in groups of four for larger objects
• powerful colour editting and copying

I intend on adding more features in the future.

The application is free to use, but I have included a Donate button if anyone would like to contribute to the cost of the certificate.

Meteor Swarm (NES)

Meteor Swarm was one of the very first games I wrote in Z80 assembly language for the original Spectravideo.

Later I ported it to the MSX range of machines, both of these versions were released on cassette tape.

Whilst programming the Game On Expo Championship cartridge, I added a basic port of the game as the third mini-game.  It was ported as is i.e. did not really take advantage of any of the NES's particular features.

So I decided to make an enhanced version of the game, that better utilised the NES capabilities, some of the enhancements include:

• two play modes: hyperspace or shield
• more graduated difficulty level
• enhanced use of colour
• additional enemy with the exploding mine

Sydney Hunter & The Caverns Of Death (NES)

Sydney Hunter & The Caverns of Death is a classic style platformer, very much suited to the Nintendo Entertainment System.

The game and concept are owned by Collectorvision, and this game will form part of the series of Sydney Hunter games released for multiple systems.

I will be developing the game mechanics, based on the engine for the Sydney Hunter mini-game I made for the Game On Expo Championship cartridge in 2015.

The original art assets have arrived and the initial phase of cutting up into tiles, tile maps and sprites has begun.

Game On Expo Retro Gaming Championship Cartridge

The Game On Expo Retro Gaming Championship cartridge for the Nintendo Entertainment System (NES) was developed for John Lester (Gamster81)'s new Retro Gaming expo in Arizona.

The cartridge contains three mini-games, with each person having to play through the games with a maximum time limit of 6 minutes and 21 seconds.

The mini-games included in the cartridge are:

• Sydney Hunter & The Curse of The Mayans
• Pedal to the Metal
• Meteor Swarm

Berzerk

Berzerk is a multidirectional shooter maze game, released for arcades in 1980 by Stern Electronics of Chicago. Berzerk places the player in a series of top-down, maze-like rooms containing armed robots.

The Astro Date is 3200 and you are the last survivor of a small group of earth people who came to explore the planet Mazeon. Soon after landing, you discovered the planet is a dark, apparently uninhabitable place. But by then it was too late to turn back because your space craft had been destroyed by Automazeons.

This version is for all ColecoVision consoles, no SGM required. Game play is a replica of the arcade, including the full original maze layout and robot placement logic.

The game does feature the speech samples from the arcade, but due to the limitations of the Coleco's sound chip no where near as clear. The original arcade had dedicated speech hardware that allowed it to play samples (unheard of at the time the arcade game was released).

The voices and sound effects are played during gameplay, without effecting the framerate, making it very close to the arcade games in that respect.

EA 70's Arcade Classics

EA 70's Arcade Classics is a collection of three classic arcade games released in the 1970's.

Lunar Rescue

Lunar Rescue is an arcade game released by Taito in November 1979. The gameplay has some resemblance to both Taito's own 1978 hit Space Invaders and Atari, Inc.'s Lunar Lander.

Depth Charge

Depthcharge is a single-player arcade game released in 1977 by Gremlin Industries. The game, presents the player with a cut-away view of a section of ocean, on the surface of which is a destroyer with submarines passing beneath it

Stunt Cycle

Stunt Cycle is an arcade video game by Atari, Inc., originally released in 1976. In the style of the Evel Knievel craze of the mid-1970s, the game allows the player to perform simulated motorcycle jumping stunts.

All three games will come on one cartridge, and be available for ColecoVision, MSX and Spectravideo SVI-318/328 systems.

Kangaroo

Kangaroo was a popular platform arcade game, released after Donkey Kong made platforming fun, where you as Momma Kangaroo have to climb to the top of the trees, avoiding harzards (such as lots of cheeky monkeys), to rescue Little Joey.

Will be released on cartridge for the MSX, Spectravideo SVI-318/328 and ColecoVision.
