Impossaball for C64

Was Impossaball ever converted to C64?

CPC: http://www.youtube.com/watch?v=IPcHyG4S-q4
Speccy: http://www.youtube.com/watch?v=ey5VbkSBSjA

If not, then someone should do it.... (not me)

It can't be done since it features advanced 3D effects which are impossible to implement on the limited C64 hardware. CPC and Spectrum both have 4 MHz CPUs whereas the C64 only has 1 MHz.

a few parallax arranged SF sprites wont make it to 'advanced 3d effects' in my book. apart from that I'd agree it's probably not possible to make it in a playable speed, counted 18 softsprites on a screen...

If the YouTube videos are anything to go by, it doesn't play at 50 fps on the Amstrad or Spectrum either.

50 fps for the player sprite and 25 fps for the rest should be more than doable, and would be pretty playable, I think.

And no, this is not me volunteering!

cpc is at <~12 fps already, and c64 has less raw cpu power, good luck playing with that :)

It's running at 12 fps since the CPC and Speccy are limited to rendering both the background and objects in bitmap mode. On the C64 the checkerboard is very cheap, ~1500 cycles gives you 7 x-expanded sprites multiplexed, with d021 for color. One sprite is free for the ball, and rendering ~15 objects is challenging but not impossible.
