Sinclair ZX80 / ZX81 Forums

[gus]

This is to share with all of you my little programming work. Today I just finished the first version of The Crystal Frog.

I'm really happy to announce this because this conversion give me a chance to stress test my new Quill Interpreter for the zx81.

The Crystal Frog was released on 1984 by KERIAN (UK) LTD. and you can found a lot of information on the WOS


The Crystal Frog is a very huge adventure. Some numerical facts: 60+ Locations, 40+ Objects, Vocabulary with more that 150 words, Status and Events Table with more that 300 Entries and more that 100 Messages...
So you will need a Sinclair with 32K RAM at minimum and if you like to test it on the real hardware... well a Lot of patience because a long load time (I will release a TK85 high speed version if there are any other Microdigital users out there)

In case your choice is to run it on an emulator, please remember this:

1) If you are using a Sinclair machine, you will set the RAMTOP before load the game, so please POKE 16389,192 (for a 32K configuration), then issue the NEW command and finally LOAD the game

2) If you prefer to use a TK85 32K configuration you do not need to set RAMTOP, the TK85 ROM makes it for you but if you are using EO, the Load File Menu Item will not work (I need to post it on the emulators forums) so you just Open the .P file and the type LOAD "" as usual.

Maybe someone want to try it out, I can assure that you can resolve the adventure with a perfect 100 % score

Here is an screenshot of the Intro Screen



And of course you have the P file on the attachment

I hope you like

>K
LOAD""

Note: Otla/XuR Fast-load is ok on EO.(SAVE"MYGRP.FL" under Vb81 XuR - Loaded in 33 sec.)

Update:

1) If you are using a Sinclair machine, you will set the RAMTOP before load the game, so please POKE 16389,192 (for a 32K configuration), then issue the NEW command and finally LOAD the game

Sorry !!!

HI Gus,

Can I add this adventure and the Quill to the ZX81 software page on my rwapsoftware.co.uk website - it is surprising how much software has been developed / released since starting this discussion board - it was certainly a worthwhile project!

Hi Rich,
That would be great !!!
I think that The Crystal Frog is in his final release, I will try to make a cassette cover in order to make the final version
The Quill is more a work in progress, but you can put both if you like

Thanks for your help and suport

Hi,

I will try to make a cassette cover in order to make the final version

I'm THE frog's specialist, on this chat !
I will try to draw a cover !

[gus]

Good !

But I thinking why are you the frog specialist...
So I know that the Citroen is a French Company and here, in Argentina, we call autorana (*) to the Citroen model's 2CV and 3CV

(*) in spanish means frog-car
