Hi,

I typed in the Poster magazine#1 program: The Valley of Adventure.

An adventure software example using ASM and Basic.

Thanks to Bogul regards scanned pages.

Hi all!

This basic program seem difficult...
But, the programer use some constants to avoid to use numerics values.
When you use a numeric value, it take more memory: number string+5bytes.
In case of constant string, it take only the variable string space.

Constants:
O=0 ; H=1 ; H1=2 ; B=3 ; K=4 ; R=23

I found 2 buggs:
1/ The "Beware..." bug.
The F value returned by "3040 LET F=USR 17040", may be up to the last monster index.
You had to add:
3045 if F<=R-K-H then goto 3051
3050 LET F=INT (((R-K-H)*RND)+ H1)
... R-K-H =23-4-1 = 18 (Monsters)
First monster index is 2.
2/ The fist level tower "Zaexon's tower"
... I don't understand this code !!!

I also add the Ratings liste in 560... a long...long ... "Print" line.
550 LET XR= (...)+H1
560 Print at (...) ; "MONSTER FOOD" AND XR=0;"PEASANT" AND XR=0; (...)

Have fun!

I would like to hear more about this adventure. It sounds interesting. What type of game is it? Is it a text adventure? What is the general gameplay like?

Necropost-bump!

This game was a huge part of my early computing life, playing it first on the PET and then on the ZX81 after typing it in from the poster with my Dad.

As a new ZXpand owner, I've downloaded the above to have a play but found it's the un-corrected version, with bugs that cause the program to crash.I have a copy on tape of the fixed version from bitd, but I'm having trouble loading it Does anyone have a copy of the corrected version, or a link to the corrections?

On a side note, I've been trying to track a copy of the PET version down (from the Computing Today listing) but have had no luck. I'm resigned to typing that in

Had a thought to check through ZX Computing magazine

Well done Fwapp !

I can debug it... 8 years after the type-in...


[EDIT] ...I had to download it from my web site...

No - thank you for posting in the first place

I've been desperate to play this for a very long time. I've been trying to get my own copy to load with no luck, and really did not fancy typing it in (again)!

The Valley was a large part of my early programming experience too. I converted the original PET listing to work on the ZX Spectrum.

I recently tracked down the original PET listing along with some conversions and enhancements if anyone is interested. I’ve long since lost my Soectrum listing.

I also did a version of Super Star Trek for the Spectrum but that’s been lost too!

Hey Dave - I'd love to see what you've got related to The Valley. I tracked down a copy of Computing Today with the original PET listing in, but have yet to type it into my PET.

This is the link to where I picked up the original PET listing and hints, tips and extensions

If you need further help, please let me know. I was thinking of gathering all my BASIC research material together on my website but haven’t got it organised yet!
