Re: BASIC V POWA ! :)

Yes double buffering is possible, but this is an OS feature rather than BASIC. You should read this - it's the manual for BASIC VI. :D This is the same as BASIC V except it has 64-bit floating point. https://www.4corn.co.uk/archive/docs/BBC%20BASIC%20Reference%20Manual-opt.pdf The manual describes a...

Re: BASIC V POWA ! :)

Is it really powerfull ? It was said to be the fastest interpreted BASIC in the world, but of course much of that speed came from the Archimedes machines that it ran on. There is actually a version for the 6502 (called Advanced BASIC), but I would expect this is no faster than BASIC IV. The differe...

Re: Arculator v2.0 released!

Ok thanks for the advice - I never would have considered removing the support podule as I assumed it must be essential. I’m not bothered about emulating the A500 personally, but if you do try please be aware that the rom does seem to be incomplete (although perhaps they are all like that ... and the...

Re: Arculator v2.0 released!

Having watched Paul Fellowes' excellent ABUG talk, I thought I would have a play with it using Arculator v2. I can get Arthur 0.3 running, but I don't seem to be having any success with Arthur 1.2.

.SSD images don't contain any protection, so I don't think that could be the issue.

*HELP

Re: Cholo challenges

Chris is right - this is almost certainly to do with other roms making PAGE higher. Have you got ADFS for example?

Unfortunately on a Model B switching off roms is not that easy.

Re: New RPG for BBC model B

I think it may work on a 1770 FDC, it’s just that you need a Beeb not a Master.

Just thinking about it, I reckon this is a contender for “Most impressive BBC game written in BASIC”. I can’t think of anything better.

Re: Most efficient ToUpper function in BBC BASIC?

That works for me too, in BeebEm. I understand why it prints the first line of output ("Inside"), but at first I was struggling to see what mechanism resets the contents of the global buffer at T% to "Outside" after exitting the procedure. I assume that it can't be affecting the global variable - is...

Re: New RPG for BBC model B

This is a very impressive piece of work! I'm not into RPGs so playing it is a bit beyond me, but I can contribute the following:

- The background files are indeed in VIEW format.
- The game doesn't run on a Master, even if DFS is selected (this leads to the "this disk title is not ..." message).

Re: Full screen parallax effect (Acorn Electron)

I think it might be that in order to look truly 3-dimensional, it has to resemble an actual scene, whereas what you have got is a series of "textured ribbons" moving at different speeds. Obviously I can appreciate that plotting scenery onto them is probably not practical!

Re: Most efficient ToUpper function in BBC BASIC?

Rather than doing

Code: Select all

C%=C%+((C%>90)*32)
, surely you could say this:

C%=C% AND &DF
This would force bit 5 to zero if it's high.

Re: Cholo challenges

Yes I also found the Ovine remake. The graphics are really good and as you say it is more or less the same gameplay. The only slight disadvantage is that user-interface type things that I knew how to operate on the BBC version seem a bit less obvious - but then I only played it for a few minutes.

On a Master, memory won't be the issue. I suspect the loader is issuing a *disc command, which drops you back into DFS.

It is straightforward to add DFS though, so that's not a major issue. There is another advantage regarding space/practicality: The base unit has a 240V output port, so you can power a monitor from it. This means that the monitor, disc drive(s) and computer only need one plug socket. Also, if you rem...
