Seaquest 99 Title Screen Seaquest 99 Screen Shot

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 NES Title ScreenMeteor 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.
