- This is a new chunky2planar routine.
-
- I decided to release it on internet to stop people from using
- does ugly copper-chunky screens and 2x2 pixels 16 colors screens.
-
- Actually this source contains 2 different routines:
- They are both optimised for fastram.
-
- Version 1:
-
- Dithered-laced, 2x2 width pixels, 256 colors.
- Linear chunky buffer.
- CPU time pr frame: 6-7 ms.
- Frame rate: 50 fps.
-
- Version 2:
-
- Dithered-laced, 2x2 width pixels, 256 colors.
- Linear chunky buffer.
- CPU time pr frame 5 ms.
- Frame rate: 35 fps.
-
- The last version has a lower frame rate, but it used less
- CPU time. This version should only be used on a little more
- complexed rendering.
-
-
- BTW: Dithered-laced means that I use a sprite mask. This causes
- a ghosted look. I try to avoid that by scrolling the pixels back and
- forward 50 fps using 2 copperlist. I think it looks pretty good, but
- if you for any reason don't want the small lace flickering and want
- to have a ghosted look instead, its not hard to remove the second
- copperlist. :)
-
-
- The routine is is based on $dff102 scroll trick used in blitterscreen1.01.
-
-
- The blitterscreen assembler source WAS A BIG MESS
- (probably the worst source I have ever seen, that's my opinion anyway! ;)
-
- So I decided to make a new routine. Which I hope is a little easyer to
- understand. :)
