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...

I guess that there are a number of adventure games with graphics that could benefit? e.g. Saga of Erik the Viking, Emerald Isle, Ransom, etc.

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.

Have you tried swapping the keyboards (with the ribbon cable) to rule out a faulty ribbon cable (or poor connection) as that can result in some weird I/O related behaviour.

the tube ula and the emulated second processor is all written in assembly lang?

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.

Re: Tubelink EXROM and UTILRAM

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...

Re: MMFS Development and Support

Could an "own file system variant" be implemented as a build-variant of MMFS like your E, M, T, U variants? In theory, it would be really useful for file management and archiving work even if some games break when booting from it. The "DFS emulating" version could still be used for playing those ga...

I am starting to wonder if MMFS should have it's own file system number and handle range: http://mdfs.net/Docs/Comp/BBC/Filing/FSNums http://mdfs.net/Docs/Comp/BBC/Filing/Handles This would allow it to co-exist with DFS, and in the Master (or a B with MER) files could be copied between the two.

Re: MMFS Development and Support

Not sure if this is by design or accident, but the Master Emulator ROM and MMFS do not work as expected when MMFS is the active file system. The emulated MOS commands that use the DFS, such as SRLOAD, give ""Bad filing system name" with MMFS.' On the same beeb, TurboMMC and a "real" DFS work OK with...
