I've been working on a 3D game using the same maze design as 3D Monster Maze. I didn't steal any actual code from 3D Monster Maze. I just used screenshots to work out the maze dimensions. No point in reinventing the wheel. This games had nods to both 3D Monster Maze and Mazogs with things like the '...

Looks good, I like the game over sequence. I'll have to read up on how to play this game. I had no idea what I was doing.

I wrote the base 1k game. It was called Chain Reaction. It's posted here somewhere. It wasn't in hi-res of course.

Got it, thanks. Will check it out later.

To answer some questions: It's written in flat assembler, so machine code with a basic front end. The Basic actually gives you the maze generation routine and the address of the maze data, so it you want to use it for something, you've got what you need. It runs find on Eightyone emulator set to 16k...

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...

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.

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...

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...

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.
