Hi,

Thanks for the feedback!

About the technical side:
1. Rubber-bars are made by changing 15 inks. Only the Red and Blue components are changed (1 byte). The Green component is the same for all the colors. So there are potentially 256 colors in these rubbers.
2. The foreground bars are made with the same technic but with 10 colors changed in the hard-sprites (2 sprites for a bar). The first line of the 6 hard-sprites is automatically repeated thanks to the 1-line rupture (R4=0 and R9=0) There are potentially 256 other colors in these vertical bars!
3. Changing all the 15 + 10 colors and the offset is done every 3 lines.
4. 64 steps of rotation for rubber-bars and 64 steps for the vertical bars.
5. The whole is moving with a MODE 0 pixel-precision thanks to the smooth scroll ASIC abality.
6. The balls are made with hard-sprites.

This intro is an improvment for PLUS of the existing effect of the Benediction's part in the 30 Years Megademo. I decided to make it just after the ReSeT #28. Thank to Brink for his music and to Pandafox to have accepted to do all the graphics from scratch in less than a week..

64K ?

That might do a nice GX4000 demo too

I don't know anything about creating a .CPR, but I think some people are able to do it!

All you have to do is making a version which is fully controllable by a joystick (it isn't the case with the current version), the using nocart, anybody can convert it.

I had the time to test it on GX4000 with C4CPC and sadly it doesn't work

It seems the cartridge does not boot properly...
I used NOCART64 to copy the DSK as CPR file, and that worked fine on my GX4000
