The levelname

and the level

So far I have taken the compressed levels from the ZX Spectrum and made the read/display routine on the ZX81. I have decided to dived the 188 levels in 2 parts. 100 and 88. The reason is that the compressed levels are built in blocks of 20 levels. At this moment I have movement and I am working on r...

For years I had the idea to make a ZX81-port of this PC game that was ported to the ZX Spectrum by Hajo Spuunup and improved by me.

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

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

Haha.... you did the same trick as I did in the character8 display.

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! LoHiRes.p Wel done, you are close to my current idea in the display so I am gonna take a look in your screen.

I had an idea how to make it work for all 8 lines.

My first try last week did not work flawlessly but my current approach is working.

This is character 8 with the even lines inverted so you get 4 lines on a character.

I need to write a manual how you can do both methods.
