Games in demo-quality?
Does anybody know games in demo quality?
Shouldn't it possible to create simple puzzle games that reach the demo-level?

Quote: Quoting ChristopherJamThough, I guess you could plot into four charsets instead and scroll by updating the character indices.
Would be cool but I assume every char has to be unique for destruction to work correctly ;)
every char can be unique, only you simulate bitmap with 4 charsets, every char displayed once and only once. when you scroll you only have to move ~1000 byte.
6rows*40 bytes = 240 = 1 charset, 6*4 charset = 24 rows. |

Ok, but those are unique chars for one screen. What about portions of levels outside it? Those 4 charsets are to my understanding sort of current visible data buffer. Hence I'd still have to copy data during scroll from outside chars where unique changes occur. My brain melts here. |

Well, yes - but that's exactly the same as would occur in bitmap mode.
At this point I suspect it would be helpful to have seperate terms for charset-meaning-level-data from charset-meaning-c64-hardware-feature.
Perhaps we should just call the former "tiles"? |

charset works exactly as bitmap in this case, only a virtual one. you *dont* reuse characters, they are simply used to only have to scroll 1000 bytes instead of 8000, and to display whats inside them. essentially you have a bitmap in char mode, in a different layout.
so when you scroll you have to update the new columns as with bitmaps. |

that would become really messy for a real game though. and slow too.
for demo things this is a nice solution though sometimes :) |

[shortly going off-topic in favor of a reply to AlexC]
Just updated the entry for Rigor Preview. Unfortunatly I do not own any original of that game preview but at least I've found an old excess release disk containing a "cracked" version. Hope it's ok to have that version added to the entry as dl.

Oh well, oh well. Sorry, somehow I was caught in a "nobody-has-it-and-it's-still-missing-on-csdb"-tunnel.
Will check what's already there more thoroughly next time;) |
