Dr Beep, your ZX81 work is truly inspiring!

Your new approach got me thinking and I've came up with a twist on your original idea and put together a simple 1K demo.

I hope you like it!

I am working on a game using this method so no time trying the trick you worked out.

The current game I am working on is a 2 part game.
100 and 88 levels, so 2x16k needed.

Very interesting.

I wonder what the Lambda 8300 will do with code like this. The Lambda 8300 does not support pseudo hires or WRX hires, as all video output is handled internally in the ULA, including the charset.

Do you need a piece of code to try?
Easiest is the BASIC code with the telephone.

I might be able to modify it, as the D-file is in a different location. If I remember correctly the D-file is hardcoded on the Lambda 8300.

I'll try to modify the Basic version and see what happens.
