Tims' Checkers
Tims' Checkers
Just released a new yet old game for the ZX81. It's old because basically it's Checkers / Draughts. It's new as I've only just published it. And once again it's old as it's based on some articles published in ZX-Computing back in 1982-83 by Tim Hartnell.
All feedback welcome, this is a beta release and there are bound to be some issues or enhancements that must be squeezed in some place. The Game is available from my blog page. https://zx81keyboardadventure.blogspot. ... -tims.html

The size of the screenmemory might be brought back to/with app. 3K with a different display method.
Re: Tims' Checkers
I was even thinking of an altered display from my 1K hires game SPY vs SPY.
This is not pixelperfect, but would work too.

Re: Tims' Checkers
I had thought that udg mode might work a little more effectively memory wise. At the moment adding any more code slowly eats from the bottom up into the wrx screen. Other than that I guess it's a trip into assembler rather than just using the z88dk libraries .dr beep wrote:The size of the screenmemory might be brought back to/with app. 3K with a different display method.

Re: Tims' Checkers
Really interesting post and links thanks!
C for the zeddy? Who knew? Certainly not me. This of course means I now have something else to add to my 'to do' list:-
Learn to solder, mostly so I can fit my ZX8-CCB
Learn some basic electronics
Learn enough Z80 to write a passable game in 1k
Learn C
A whole host of stuff on my Beeb (finish learning 6502, BCPL, Forth, finish my TurboMMC explorer, write the same for ADFS, the list goes on). I actually have C for my Beeb but it won't compile on modern hardware such as MMC or my Datacentre or even my BITD Opus Challenger floppy disc drive!
Strictly speaking I kind of know C having written several embedded programs for smart bar code readers about 10 years ago but being honest I really had no idea what I was doing! It all worked and we got paid so no harm no foul I guess.
I am in the car so research is a bit difficult but is there a 'Hello World!' project for C for the zeddy anywhere? Having something that compiles and goes makes getting started so much easier!

Re: Tims' Checkers
Just have a look at Z88DK:
https://www.z88dk.org/wiki/doku.php?id=platform:zx81
And if you do not find enouth C exaples there: I can post the C-source of ZeddyFox: the brower for the ZX81 using ZeddyNet (all written in C and Assembler)

Re: Tims' Checkers
Also, there is an excellent document written by members of this site. I got and keep finding a lot of really useful information out of it, plus It's a great intro into the otherwise initially slightly obtuse information on the z88dk page.

Re: Tims' Checkers
Z88dk wouldn't exist on the zx81 in the current form without the huge support we had from this German zx81 lovers group.. it is along story, I can tell later.. but zx81.de can be proud of it.
