It seems that the version is not working on >2K.
Probably the SP or copy in highmem.
Will try to fix it.

Maybe it is just that ZX81 loading routine tries to expand the display file as it always does for 4k or more RAM ?

Could be. Will take a look. Screen is indeed on a illogical place.

Compressed screen was the problem.
Now I have 2 versions due to compressed screen.

I need to find a way to built 1 version.

This game is really the first program not to have room for expansion of the screen.
I have an idea, but I need to test it.

Well, the idea didn't work,
but another idea did.

I have set a shadowscreen in higher memory.
Machines with less memory will fall back to available memory.
It costed 5 bytes to fix it, but I managed.

Game now tested on 1K, 2K, 4K, 8K, 16K, 32K and 48K.
All runs perfectly.

New download in the gamesection. New source will follow later.

See also remarks in the sources of game 11-20.
Spacetrip is a fact. See other topic for that.
