Thank you.
Known, but for me an unusual method. Although a couple of places it is inserted in the program.
A couple of hundred bytes can and will. From the original rules do not have enough earthquakes ... ;)

Found a good book - ExplorersGuideToTheZX81.

What If?

IF developers zx81 initially added 1KB RAM at 2000h?

Elementary diagram, and initially a possibly computer graphics would be greatly improved?
Two additional sets of characters, or turbo loader, or ... :roll:

P.S. With this addition, my game will work, I'm sure. ;)

Fixed two small mistakes in game.

UDG may be transferred to a separate file downloader, 3 or 4k will be free.
And it will be possible to test renumber Vb81XuR - he flew out earlier. ;)

But it is if I have free time...

P.S. And, here and fasten the same transfer standard 1k for UDG.

P.P.S. Tried to remove the UDG in a separate file - approximately 1600 bytes free.
