I guess it's possible the Master is using a different algorithm, or there is some kind of rounding going on. Bresenham circles are, I think, slightly more pleasing if you use (R+0.5) or (R-0.5) as the radius. The half gets doubled in the formula so you're still doing integer arithmetic. It could be...

I don't know who they are but they've been slowly releasing a bunch of old Acorn source code and documentation:

That would be great, thank you.

LineParser::GetValue sees the dot and thinks it is a floating point number. istringstream is used to parse the number and it fails, as expected, returning the value 0. This causes it to report the new stream position as -1, which gets cast to an unsigned value of 0xffffffff, so beebasm thinks it has...

This is really nice.

If not no worries I'll write a script to convert assemble and produce a listing file.

I wrote a hacky awk script to convert it to beebasm format. The script and the resultant symbol file are attached.

I didn't notice you'd got it working until I'd nearly finished changing it to run on .net core. So in theory it should run natively on macOS now. Note that the instructions are quite different.

The animated bus works fine using the old version on Windows and using the new version.

Yes, it's this one: https://stardot.org.uk/forums/download/file.php?id=54199&mode=view That gif works fine for me on Windows 10. The failing line of code is the one I thought might have a problem with a static gif because it reads the inter-frame delay: byte frameDelay = (byte)(ushort)((BitmapM...

Any idea what's wrong? Silly question, is it an animated gif? A non-animated one might confuse it. Or edit the compilation line in build.bat to read: %CSC% -debug -define:DEBUG -out:bin\img2beeb.exe src\Program.cs src\Properties\AssemblyInfo.cs -reference:WPF\WindowsBase.dll -reference:WPF\Presenta...

In 2018 pixelblip started making animated images, and, again, somehow -- how?! -- a few of them were converted , by ctr, into a format that could be played on a real Beeb (or in emulation). :shock: =D> =D> I did a little tidying and uploaded my code to github: https://github.com/mungre/img2beeb The...

Level 18! This thing is a time vampire.

Finally did 13 with only one life lost, straight through 14, floundered on 15.

..and got to the funky 'stick' level. Almost got it done

That's what I thought!

Still level 13. I can do the hard bit, but not the really hard bit.

I can't figure out how to get the tripod and still finish level 11, but I can get all the horseshoes now. 12 was OK, 13 requires a great deal of precision. Which I failed at.

Level 11 is fiendish. It seems to have two things that need to be done last.

I wasn't going to play again today but then I was waiting for my dinner to cook...

Level 10: 120,560

I had this back in the day but it never appealed. Liking it so far though.

48,755

Only a small bump. I've been trying a different playing style - only shooting the attackers - and it's taken me a week to beat my old score.

5,360

I got to level 4 but only 4,840. I guess flying ones score more?

No, Apache can do content-type for you. You just need to tell it that ssd files have mime type application/vnd.acorn.disc-image.ssd (or application/octet-stream if you prefer). I haven't used Apache in years but a quick Google suggests you need to add this to a config file: AddType application/vnd.a...

On Windows 10 it works fine for me in Firefox but Edge is guessing the type because the response doesn't have a content-type header. The generic content-type for "this is a binary blob so don't try to display it" is "application/octet-stream". Alternatively, Tom Seddon is using &...

Cheers. For me it was actually the first screen the second time through. I'd had an absolutely blinding run hitting loads of enemies with fruit and then I threw it all away! I've completed that level once before but my score was nowhere near as good.

Had an amazingly good run (by my standards) and then lost all my lives(about 3) on the same level!

Ditto. I also thought this will give me a clear lead over fwibbler...

37,100

Level 1!

29,000

I decided to have just one more go...

17,800

Level 3!

12,000

I didn't know this was a thing on the beeb. It's a bit tricky.

7,200

It's worth remembering that this is a dispute in America governed by American law. The law is different in the UK. For example, "fair use" is not a thing, but the use of a trade mark in an educational video is not a protected use anyway. Of course, if you post content on American sites you...

Thank you! It is a useful reference.

Another random guess using only reads: a read of &BExx latches xx, then a read of &BFyy writes yy to cmos address xx. Stephen's method does look simpler though.
