interesting little demo. I think I can improve my routine in WGWTWTOTGS and make something cool with it.

It should begin "In Krestage 3 the...". When editing is disabled, can we at least have a preview? :/

Krestage 3 the 50 pixel sprites depend on flipping MC mode at the right spot. They are X-expanded sprites with an extra expanded pixel. The way it works is that it fools the MC display logic to start with pixel 1 of 2 when the sprite is already on the last (hires) pixel of the sprite. pixel two of the MC pixel is then displayed even though the sprite data is all shifted out.

Sure you can split colors within the sprite. Note that the exact position of many split effects are dependent on which generation of C64/VIC-chip you are running the effect on.

I believe the 50 pixel wide trick is done by toggling the mcol/hires sprite toggle at the right time. Although the extra 2 vertical lines are a repeat from previous definition.
More colors are possible non interlaced via pal blending. And also the color mix varies according to whether or not specific colours are in even or odd lines etc

I also learned more about how the VIC chip works. Initially I thought that it fetches ALL data (bit pattern, colors, x-position) at the right side of the screen. But it fetches only the bit pattern. You can still change for example the sprite colors before the bit pattern is displayed on screen.

I do not understand yet completely the 50 pixels wide sprites in Krestage 3. In the comments of that demo on youtube it is mentioned that you have to change the x-expansion register at just the right time.

Which makes me wonder: can you give sprites EXTRA COLORS by changing the color registers at just the right time?

@MrXaliasH Lol, I started this when I was learning to make a stable raster interrupt. When I saw "Krestage 3" I thought that was a nice application.

thx for this proof of concept!
for newbies (as i am) those hacks may be usefull ... someday ... when i master the timing problem comming with those damn raster interupts ^^

@oswald. Probably because it is not of much use same as the 50 pixel sprite method. Although nice proof of concept

btw, if sprites are reusable horizontally (eventho no new data shows up) why this hasnt be used so far?

Almost as weird as Krestage3 itself.. in a positive way of course :).
