Sinclair ZX80 / ZX81 / Z88 Forums

Pokemon, did they work on the real HW eventually ?

Not yet, didn't had time that weekend but hope on this weekend.

Some of the games are working on real hardware, some not.

mastermind.o => ok
joust.o => ok
luna.o => ok
hilo.o => ok


blackjack.o => no
(start after run, bet okay, after choose of cards the display is corrupted after a few seconds, seems to be a wrong value in I register / wrong pointer to char table)

tictactoe.o => no
(start after run but program wiped out, come back with K cursor immediately)

worldpuzzle.o => no
(crashes after start, no display at all, black screen)

riskdice.o => no
(start after run but program wiped out, come back with K cursor immediately)
(crashes even in emulator, first 2 questions answered, after black screen forever)

fast-furious.o => no
(crashes after start, no display at all, black screen)

Thank you for the report !
I'll do my best to try understanding what's bad..

I revised the source adaptions I made for the ZX80 but at the moment I couldn't find much.
It could have to do with some critical register I'm not protecting enough.. what I don't understand is, in example, why tictactoe is crashing while joust doesn't they are both using the same console functions, and why it is not crashing the emulated Z80. Joust is bigger and tic doesn't use advanced mathematics or things which might corrupt special registers.
Here's a slightly modified version, just to see if the problem persists.

More crap.. really ! It is a direct compilation of "Monty Python's Bridge of Death":

Don't say you weren't warned

It is the only game in this list I wrote myself.
Shame on me, presented it in the minigame compo in 2003 and classified second to last !
Well there are many good reasons for this .. not telling, but don't expect a killer app !

I've developed a version of Tic-Tac-Toe for the ZX80 which is now finished. It works on the unexpanded machine so there is no AI - it does however check for a winner - this was the most memory costly bit of the whole symbolic listing so you're welcome.

Any tips to save valuable bytes are welcome as it'll help with my next game.

It is nice already (and cute).
My cent is on the compare expressions, you may substitute: IF J=0 and IF A(I)=0 with IF NOT J...
I also wonder if the "TO" function on a string vector could help in place of a DIMensioned variable.

This version is for 4K ROM, so the string manipulation as per the ZX81 doesn't work.

Booleans on ZX80 (4K ROM) BASIC are returned as -1 for true and 0 for false.

Thanks,

Shaun.

So here's another 4K ROM ZX80 release for you. It's a cost-reduced version of a fruit machine simulator.

The player starts with £5.00; Type R to roll the reels. Any other key to leave the fruit machine.

Here is the win table:

£££ = £10
$$$ = £8
XXX = £5
OOO = £2
--- = £nil

££? = £4
$$? = £3
XX? = £2
OO? = £1
--? = £nil

As I ran out of memory to add in any mini games, not that one can achieve much with the 4K ROM and BASIC anyway

Enjoy,

Shaun.

PS, This game will be part of a collection released through Monument Microgames.
