Ambush:Reloaded . Hope there are no flicker.

Cool, except I’m not very good at C. Fortunately, bank switching isn’t rocket science, I think I’ll manage. ;)

Re: F'n Balls

M’kay, this is a little puzzling. The loader is trivial enough to fix. Replace LD A,$11 at address $5b17 with LD A,$14. Now, the runtime code at $f1da is tricky—I can’t find it on the tape image. I guess it’s generated at runtime. P.S. It is. There’s a lot of block moving and memory rearrangement (d...

Re: Why is a simple B&W line drawing 4 megs?

JPEG compression is adjustable, so it doesn’t have to be four megabytes. However, JPEG is lossy, and the amount of data retained vs. lost determines the size of the file. Now, simple images with little variation in them, will compress well without losing much quality. However, in your example, the t...
