I've gone with compiled sprites, and decided to ignore sub-byte
masking, at least for now. That gave me 18 or 19 sprites until I wrote
code to erase them afterwards, which cuts it to a measly 3. Suffice to
say, I'm going to look into other approaches for that step; it's
taking something like 6.5

If I have, say, 40% of a frame to spend on it, how many sprites, and how

Maybe around 4-5 sprites of 16x16 pixels? IIRC my Pac-Man emulator has about
half a frame to draw 6 sprites of
That's really encouraging; I'm now obsessed with getting a complete
game working at 50Hz and in that context I think even just two or
three sprites would do it. The arbitrary 40% came from what was left
over in the current demo but it strikes me it's also very close to the
amount of time between
No apologies required, looks very good to me. So if you're not in a
position to turn it into a full game, would you consider turning it into
a bit of middleware?? A bit cheeky I know but I'm sure it would find a
good home somewhere, probably for many. I made some experiments with
'full
I read your blog a few days ago I think; it's Splitting Images isn't

people like myself going to have to find out what people like David

It's very cool to see scrolling that quick and smooth. :-) We just
need someone to use it in a game now!!

It's exceedingly rough and a pretty simple effect that I'm sure has
been exploited a hundred times before but I thought I'd throw it up as
is as my part in maintaining the fantastic momentum we've had lately.

It's explicitly not a mere demo effect;
Nice!
When you say the tiles are 'precompiled', have you used a sprite builder
to print the deltas? If so, I'm confused about the left-hand clipping
if there's no real scrolling involved. Surely you're not printing all
those tiles each frame?

No, there's no deltas in that sense. I just mean that I've got two
routines — DrawBlock and DrawBlank — each of which draws a whole tile
at (hl) and then returns. Betraying my dense level of thought, they
both look essentially like this:
ld (hl), b
inc l
ld (hl), c
