Re: New version of Centipede for the BBC Micro (in progress)

Sorry, i've been very slack with this, but I haven't forgotten; lost a day to sound as usual.
Here is a small update with some sound, should support keyboard and joystick (fire to activate, then you can use both).
I've still got nearly 5K free and can't think what to do with it all :lol:

Re: I got my new beeb!

Looks in nice condition, as has been said, no extras is good for compatibility and less to go wrong. The MMC is good for when people remember the beeb and fancy a quick blast of something they vaguely remember, but it can be tempting not to give a game a fair chance. It is also an easy way to add mo...

Macro changing palette for me too.
It might be a good sanity check to produce a table of addresses executed per frame. Summarised in ranges would be good just to see where all the time is going, but I probably won't be using it ;)

Hopefully you have the rom by now, if not, I think the rom is on the disc image. You can extract it with the MMC utilities or been. If not, I'll dig out mine and post it tonight.

Re: Acornsoft P-System

I'm fairly sure one of the c compilers targeted it, but it may just have been their p-code. From my memories of a review, C's p-code was a little faster than basic, but the standalone c was a little faster still.
Please no flaming about benchmarks ;)

Welcome,
Most of the docs for the turbo mmc apply to smart spi.
If you are planning on using the floppy, read the cautionary posts.

Re: Fixed: Enhanced Exile + TurboMMC compatibility? (patched Exile)

Those sideways ram boards use pb0/1/2 to select the write bank, which tends to make the next mmc operation fail.
Resting the MMC causes the currently selected SSDs to be reset which them brakes games launched from the STL archive menu to fail.

Re: if you make me mad, i will

Having the assembler built in was what really drew me to the beeb and as you say, makes mixing ASM and BASIC easier.

I haven't read the full list of requirements from the BBC, but having a built in assembler makes sense for getting the country programming.

Maybe not the best thread, but here goes. I would like a utility to load a chunk of memory into sideways RAM that is compatible with the various MMC devices/ROMS: TurboMMC, SmartSPI and MMFS.

Re: Memory-efficient decompression for embedded computers

Phantasm, when I was doing mine, I found that rather than having 1+7+8 bits, other ratios were better, but I like your idea of having 8 flags together and then whole bytes for size and offset.
