Re: What do we need for a "How to program the X16" book?

I would start with the Commodore VIC-20 User's Guide, which does an excellent job teaching BASIC. Then I'd modify the machine-specific instructions to work with the Commander. I did a pretty exhaustive look over the manuals a while back. The two that stood out were the Vic 20 and the Sam Coupe as b...

Re: What do we need for a "How to program the X16" book?

First decide what it means. What is your "target market" ? Commodore machines tended to have two manuals (according to Bagnall's book this was pushed through by the engineers for the Vic 20). One was "An introduction to programming" which tends to have a very cheerful bunch of th...

Re: My first foray into ASM. Advice?

Don't do it on the X16. Initially. There's a reason for this. There are countless C64 tutorials, books and tools available for nothing (there are for the X16 just fewer) which gives you a big choice at all levels, depending on how much knowledge you have ; everything from absolute basics through to...

Re: Lost game from the '80s: Scumbotron!

My (Neo6502) version, not quite complete. No Brains .... and obviously no collision detection which makes surviving easy but scoring a bit difficult. https://www.youtube.com/watch?v=tzpN1NQkSEk Oh! I missed that - it looks fantastic! Now playable :) https://www.youtube.com/watch?v=wik5QBKo2SI

Re: Some things I've been working on

If you can do your filling using horizontal lines it should be *much* quicker, because you can just blat a series of bytes at Vera. Incidentally, I wrote an algorithm for Stefany Allaire's machine which is a Bresenham Approximation, it's a cheat variant of Bresenham where basically everything is sca...

Re: Lost game from the '80s: Scumbotron!

Very nice implementation of a Robotron-a-like. Maybe add the control system on Jeff Minters' own version, which I always liked, and means you don't have the twin controllers issue.

Re: VERA FX demos for VCF

Awesome :) Do you think you'll release the source for these demos as well? It would be a good example of how to use the FX features. The source is already available on my GitHub. Its not (at all) cleaned up yet: its part of a hardware test suite right now. (GitHub link : Mario Kart is in "tile...

Re: VERA FX demos for VCF

Is Mario Kart for real or a cheat ? The 2Mb requirement made me wonder ; there's a pretty demo on here which looks spectacularly 3D but is really just all pre-calculated and rendered simply on the fly ; it's not doing 3D in real time. Not knocking the project, looks great ; things that Vera was rubb...
