Cavern FighterWell I thought it was about time I started to get something new out there! Obviously still going at restoring all of the old titles, but I have also discovered (and recovered) the source code to a few games I was working on. I have dusted off the Z80 coding part of my brain and got one of them up and running enough to take screens shots.
The game is called 'Cavern Fighter', it is a take on the arcade classic Scramble. It has a full six levels, similar to the original arcade game, each level introducing a new element, taking you towards the final confrontation at the end of level six.
The game is basically working, with collision detection, scoring, but still needs some more play testing, more game sounds, music, title screen and intro mode. I publish more as I make progress over the next few months or so.
It has been designed so that it will still work on Spectravideo machines (although not sure I will limit it to the SV-318's 16K of memory) and MSX 1 machines. But I have tried to use appropriate techniques to make it as colourful and vibrant as possible. Last Updated (Saturday, 24 April 2010 21:23) PyxidisStrange name but still a cool game! A vertically scrolling shooter, with ground and air based shooting, multi-colour sprite use, challenge stages, power ups and end of stage bosses. To get this one to fit in the SVI-318's 16k of RAM (12k practically available), I had to make the 3rd level a little shorter than I had originally designed and drop the music that I had created (probably a good thing - music is definitely NOT my strong point). The game is quite challenging and it can take a bit of effort to get through all three stages, and then the movement clock is doubled making a harder set of the same three levels to get through. I still to this day regret that I was never able to produce the 1,000 copy sample requested by ASCII corporation in Japan, it is interesting to postulate on what would have happened next. Pyxidis was still the biggest selling title from Electric Adventures (followed by Video Graffiti and Frontier), with many of my later teenage computer collection funded by the sale of the titles.

Birds of OrionThe 2nd full machine code game, BIrds of Orion is a typical blast the aliens from the bottom of the screen game. Once again like Meteor Swarm the difficulty level is pretty hard. The aliens are animated, and the action is pretty fast and furious. Released in 1986 for both Spectravideo SVI-318/328 and MSX machines. Runs in 16k.
Beyond Basic 1 to 5 - ReprintedI have managed to get five parts of my Beyond Basic column (1st published starting 1988), that look into ways of extending MSX Basic using machine code routines. These articles include machine code listings and sample programs.. The five parts I have re-typed are: Last Updated (Saturday, 13 June 2009 19:07) |
