Random maze generation game
I thought it would be interesting to try and write a machine code version of an algorithm I read years ago in a book of ZX81 basic programs. I've managed to get it going and I think the results look quite good so I've made a micro game around it. This program has the title screen in Basic. You can s...

Re: Moon Patrol
Looks really good but clearly unfinished. Perhaps you should release the source code and let someone else finish it if you don't want to take this any further.

Scrolling up one pixel
When I was writing my giant letters utility, I had thought to make each letter scroll up not one line, but one half line - a ZX81 pixel. The routine I wrote was too slow to be of much use, but here is is in case anybody might like to make use of it. It doesn't clear the bottom line as the routine to...

Giant Letters utility
Here's a handy utility to display giant letters on the screen. Input a string and see it turn into giant scrolling letters. This could be good for a display for a computer expo etc. It will support colour if you have a Chroma interface but works fine with a 16k ram pack only. Giant letters1.jpg Gian...

Re: TRACTOR BEAM UDG
No joy with the Eightyone emulator, it just crashes or uses normal graphics.
Wouldn't it be better if the I register was normal for the title screen then switched to whatever the new value should be for the game? The score and bonus messages wouldn't work however.

Re: Tractor Beam - Galaga style game
That is really cool!!! Can you tell something about the Making-Process?? Greetings Jens Made using Flat Assembler. It's entirely in machine code and even leaves about 1kb spare so memory efficient. As you can probably guess, the aliens are following preset movement tables. Every alien has a home po...

Re: Tractor Beam - Galaga style game
No objection. I take it UDG requires a modified ram pack and as I don't have one UDG wouldn't work on my hardware. As the aliens are all single letters, it might translate quite well into UDG

Tractor Beam - Galaga style game
Here's my latest game - Tractor Beam. Inspired by the 1981 game Galaga, this game features most of the features found in the arcade game. The aliens can capture one of your fighters using their tractor beam. Shoot the alien that got your fighter when it's attacking, get it back and join two fighters...

Masada Class reissued with 100% machine code
I decompiled my old 1994 game Masada Class and have replaced all the basic routines with machine code. So things like the "one letter appears at a time" style of message writing that I may have thought looked cool back then is now running a lot faster in machine code. I've also updated the special e...
