Re: Circle floodfill ideas?
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...

Re: BeebAsm
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...

Re: Acorn Art Thread
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.

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.

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).

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 &...

Re: High Score Challenge S11 - Donkey Kong Jr.
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.

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.
