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 ;)

Re: first post / introduction

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.
Have a look at bbcmicro.co.uk for some more modern 2000+ games to add to your beeb.mmc and lookup *DBOOT

I seem to remember that for program listings, the code was already therea and typing just made it display, but I can't remember the details.

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.

My approach of ON ERROR seems OK, but it isn't very nice. I was wondering about checking which ROM was the c...

An analogue joystick will work or analogue mouse on an emulator, but a paddle is best.
It is actually an emulator running the original arcade ROMs from Exidy.

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.

Re: if you make me made i will

It may not help, but I think if the disc isn't there, it tells you, so a beeb.mmb with only the menu could be used to find out the disc number.
SmartSPI supports multiple archives, so you could have them on the same SD card :)
