Software sprites are also known as bobs.

Well, Boulder Dash is the obvious first one to mention (everything is soft sprites, showing it's Atari 8-bit heritage there...) and there's some big character-based bullets in Salamander or the Turrican series, the green attackers and men in Dropzone (again, it's from the Atari) are all soft sprites. The nasties in Extreme are char sprites too, but the they only step a char at a time so it's a little rough. One of the IK+ fighters is chars as well (the original International Karate on the Atari uses a mixture of char sprites with hardware sprite underlays to get the colours up).
The short answer is don't use 'em unless you're really desperate and, if at all possible, keep them fast-moving to avoid having to do sub character steps. If you need to go smooth, precalculate the horizontal shifts and preferably the vertical too as far as y'can, that'll help a bit. Oh, and it's a total fucker for CPU overhead! =-) |

My opinion is, that bobs moving only quantized with the chargrid don't count.

Well, strictly speaking a "BOB" is a Blitter OBject so the C64 doesn't have 'em at all since there's no blitter. Software sprites can be anything from char-stepping bullets to fully rendered and masked objects on the bitmap. |

I could be wrong, but if I remember it correctly Goonies was all multicolor bitmap.

Also Conan (by Datasoft too), and Karateka. Wings of Fury relies heavily on software sprites too, though not exclusively. |

If you are looking for software sprites, look at all the games ported from ZX Spectrum. For example "Fairlight", "Underwurlde" etc etc, there are so many of them. |

Underwurlde is interesting. If I remember, it uses sprites for the enemies, and bitmap for the bubbles & rope in the caves, but manages to retain quite high framerate. |

Doesn't Barbarian write to bitmap as well...? i seem to remember it leaving objects behind sometimes. |
