Re: Which C Compiler?

Interesting. For a Pi-hosted solution then a good start would probably be to port ncurses/curses as that would make a lot of command-line tools and games easier to port. Does anybody have interesting open source projects for a 6502 based Acorn computer in C out there I would love to have a look? Fro...

Re: Doom?

Maybe the textures could be dithered when read by the pi (or just preprocess them so they are stored processed) in order to add more nuance?

Re: Software for Constructables (Model-making, pattern making etc.)

Slightly off topic wrt to OP, I guess, but I remember seeing Beeb-controlled CNC-machines during a factory open day visit to GEC in Rugby as a teenager.

Re: A blitter for the beeb?

mlouka, I'll look at those suggestions - do they use GXR extensions do you know? I doubt it as they work on the Model B but I suspect that they use the built in vdu-calls for drawing which I guess would make the calls easier to identify/hack. There are probably some Master-only educational titles t...

Re: Which C Compiler?

I haven't tried benchmarking to compare it with BASIC but it seems reasonably quick. My flappy bird clone is playable even though it looks a bit primitive as I only used lines to indicate where the bird and top/bottom of the columns are. I used a modern text editor -- just made a little script to qu...

Re: Which C Compiler?

I wrote a flappy bird clone in December/January using Beebug C to create a standalone executable. I had no problems with the compiler but I ended up using a little BASIC program to set up the display and slim font in order to use Mode 5 on a Beeb and Mode 1 (129) on a M128 as I ran out of memory on ...

Re: BeebEm Mac - Info

Why does it have to be moved in that way? :?: I guess that's just another way of removing the security restriction? It's not really of any consequence as this will all be resolved soon enough anyway. I don't think it has to do with security as you still need to give it permission to run. You can ex...

In case others will find this useful, this is my little cheat sheet for the FX calls. Print it out at 100%, cut it to size, then leave it on top of your beeb for easy access.

Very nice. Will this require the VideoNuLA or will it run without with “interesting” colours? I’m also a little curious about how you are doing this.

That's because *CO. matches *CODE in the MOS as the MOS is checked before any sideways ROMs are checked. If you really really want to embed abbreviations in code you should only abbreviate it to such an extent where it still makes sense in English, ie *Config. *Desk. *Del. not *co. *des. *de. Stric...
