Re: Scanning

That's an interesting approach to the task. In my case, I'm on Windows 10 with a Brother A3 multi-function printer/scanner/fax/copier thingy that I was given for free by someone who was having all sorts of nightmarish issues with it. Turns out after much delicate ink-soaked paper remnant removal fro...

Re: Disassembly of Orlond's Meanies (written by Terry Blunt)

Does anyone know why the negatively numbered keys are numbered the way they are? Is there some sort of pattern to it? Scrub that, the code using keyboard scan codes. The BeebWiki at MDFS is a fantastic resource for keyboard scan codes. I guess it's a reason based on the layout of the tracks of the ...

Re: Disassembly of Orlond's Meanies (written by Terry Blunt)

I've taken a quick look and it seems to be using OSBYTE &7A to read the keyboard. This is at address &5631.

I'm now going to check around here to see where it checks for being hit by a meanie, but I'm feeling like I'm getting closer.

Since you've already found where the number of lives is stored, you can easily give yourself infinite lives by replacing the DEC 80 with a couple of NOP's. Yes, I've done similar so far, but when you lose a life (and it can happen quite often) you are taken right back to the initial starting locati...

I thought some of you more artistic people would have increased the number of spheres, changed their positions, etc. and rendered a new scene or two. Maybe due to the time it takes to generate each scene that soon would get boring. I love the nULA version with increased grey shades. Very nice, but h...

Re: Any short type-ins for unattended Beebs?

Attempt to write a program that draws non-overlapping filled circles onto the screen.

That takes some doing, and gets you thinking too, or try to write a mandelbrot drawing program (slow in BASIC but entertaining nonetheless).
