Re: [D_File] Something's wrong in this code.

I think the problem is you are poking the DFILE system variable (16396 and 16397) to change the location of the display file such that it points to each of the 10 different screens in turn, but crucially the two bytes are not changed at the same time. This means that after location 16397 has been wr...

If you have real hardware with tape loading, I’ve read you can load with RAND USR 836 to stop auto-run. (This I’ve never tried myself.)

Does anyone have a scan (or photos of each page) of the book "50 Rip-Roaring games for the ZX80 and ZX81"?

Re: SYNTAX ZX80 and other docs

Volume 1 only consists of 2 issues - November 1980 (number 1) and December 1980 (number 2). January 1981 is volume 2 number 1. So the archive isn't quite so bad as you think.

You've done a really nice job with the graphics, working skilfully around the limitations of pseudo hi-res. :) Horizontal movement will be challenging unless you opt for moving the sprites one character cell at a time. But I think that would work fine and would still look good. It w...
