Re: Clone Wars (Scramble): vote
Well to be honest it doesn't have a title and there is no release date as it was just done as a laugh for a competition. You could call it "Crap 256 byte Scramble" I suppose Don't you prefer to call it something else, for instance "Scram256" (as the name in your files)? It's def...

I vote for my Crap 256 byte version that was done for a competition I will add it to the archive. What's the exact title of this game? What's the release date? What's the competition?

Re: What differences in programming Spectrum and CPC
I only did one conversion from Speccy to Amstrad (Gunboat by Accolade).
That was fairly easy because it was solid(ish) 3D so most of the drawing was just horizontal lines.

Re: unsigned to ascii
As above, if it's a simple score counting down, just store it in consecutive bytes as ascii chars (48-57 decimal). To decrement the score just decrement the bottom char and if it goes to 47 ('/' char), set it back to 57 then go to the next char and decrement that. That way the score is always in the...

Re: Race games - how is it done?
I told Psygnosis that if they wanted to see more details like dips, hills, trackside objects, other cars etc. then they'd have to pay actual money but it never got any further - for "political" reasons it didn't get a green light - but it was a fun thing to code up I remember. It was inde...

Maybe start from this link. It's not directly Zx Spectrum related but tells quite a lot abouth algorithms.

Re: BBC micro differences and similarities
Non-interesting fact No.1 I wrote my first game on the Spectrum simply as an effort to get enough money for a BBC Micro and a copy of Planetoid (although it was originally called Defender until renamed for fear of copyright issues) https://www.youtube.com/watch?v=9f5Hzm7B4xU&t=5s My ploy worked ...

Re: Basic VAL function
The above is all relevant and correct but it was especially useful in Sinclair Basic on the unexpanded ZX81.
With only 1K for screen and program, every byte was even more important than on the Spectrum.
It may have been that it became habit and as mentioned, if you can save bytes then why not?

Just back from holiday... No it's not in a magazine but I was the coder of the C64 version as all the 8 bit versions were done by us.

Re: Themed picture quiz - miscellaneous stuff and sundry
Originally called Sphericule till USGold made a deal with Accolade and they decided that the Americans wouldn't like the name Didn’t know that, or I'd forgotten if I did, is that in a magazine somewhere? Perhaps it could be added as a comment in ZXDB. In this case I prefer E-Motion, a rare case whe...

Re: Amstrad CPC
You might also notice a similarity with the BBC micro. Could be because they both used the Motorola 6845 video generator.

Re: Double buffering on the Spectrum
As already mentioned, there is no definitive answer. Being pedantic I'd like to leave the double buffering term for the 128k ability to swap memory whereas I'd always call the term of writing off screen then copying to the visible screen as back buffering. But that's a moot point. Most solid 3d stuf...
