Sinclair ZX80 / ZX81 Forums

Maybe the most ambitious Pacman was posted by Brian Lewis, pseudo-hires and the behavior of the ghosts was supposed to mimic the the original.

PS this thread should probably be moved to the games section.

There are literally dozens of versions, commercial and mag type-ins. All the early 80's arcade hits had ZX81 versions, Defender, Scramble...etc. There are probably 20 or more versions of Space Invaders. Of course the quality varies greatly. Most of these are available in the ZX81 software collection...

Versions of Applesoft's HLIN and VLIN commands for the ZX81.

See enclosed .txt file for more info.

If not too hard would it be possible to make the disassembler window resizable? I find it a bit constricting, especially when the contents of the registers are being shown. I'd also like to see wider columns, these are sizable, but restricted because of the size of the main window. Just a suggestion...

A few are "Open Access", like the Quicksilva article I posted yesterday. Here's another one https://www.tandfonli...

First hand account of working for Quicksilva. Lots of interesting information. Nice downloadable PDF available.

Using the ROMs find line address routine at 09D8 LINE-ADDR. may work better. or not, for your REM loop. For a given BASIC line number this subroutine will return the starting address of the actual line or the starting address of the following line if it does not exist (C reset). 09D8 LINE-ADDR PUSH ...

This line...
10 LET X=16623

Produces a false error message!

This line...

10 LET X=Val "16623"

Avoids the error message.

I've seen this bug before with other values as well, weird huh.

See the attached.

High Rise Hive is a HogRogProg game. See HogRogProg Collection in the games forum for more great games by them. I really like Bug Burst myself.
