Event id #2655 : 8K Intro Competition 2017
Inspired in part by Didi's past intro creation competitions (many thankings for those!),
have a four week lightning competition to help you survive the holiday season
- single file one part intro (fade in/out acceptable)
- has a logo+changing text+music
- file size of at most 8192 bytes, including load address (so, 8190 bytes of data).
- no more than 5 seconds decrunch/precalculation time.
- once page is running, exits within 5 seconds of pressing space (should be obviously fading out)
- don't trash any RAM from $2800 to $cfff inclusive (unless you restore it on exit).
- entries uploaded to csdb as runnable .prg, optionally embedded in .d64,
- max three per participant, withdrawals allowed, older entries will be displaced if you've too many.
- competition start: 8th December
- entry deadline: 5th of January, 14:00 (2pm) UTC
- voting deadline: 12th of January, 14:00 (2pm) UTC
- entries will be ranked by CSDb rating, including private votes.
- entries with the same weighted average will be ranked by their percentages of 10s, 9s, etc.
No prizes, just fame :)
Thankings to Jeanette, Krill, Groepaz, and various ICC2016 commenters for helping me to crystallise plans.
Any errors in judgement all my own - I've ignored a lot of good advice :D

So can we use $d000-$fff9 for generated speedcode or gfx buffers? (Accessed from $0801-$27ff) |

Wonderful! 8k is inally a halfway decent limit! \o/ |

Have fun with it. Maybe better not to have the same rules every year. :) |

8KB is very decent limit, big enough for some half-decent graphics, a decent tune and some code that should rise above the simple swinging logo + 1x1 scroller. |

This means in runtime? Usually depackers fill the holes ($2800-$cfff in this case) with zeros. I've been trying the Exomizer level option (which should leave the non-used memory untouched when depacking $0400-$27ff and $d000-$ffff), but can't get the depacker source to work, yet. It'd save some time if I can just use the sfx option. Then you can pretend there's game bytes at $2800-$cfff. :) |

Quoting HeinThis means in runtime?
Yes. I was assuming game gets depacked from that area after the intro exits, possibly getting moved down to $0801-$b000 first depending on the packer requirements.

Interesting. Perhaps I should be louder about nucrunch offering a stream containing multiple disjoint areas... Or is that what the Exomizer level option is?

I'd prefer to leave the rule as it stands; while I considered adding a specific payload, I didn't want any of the entries taking advantage of whatever the contents were (which would in turn have tied those entries to only being able to intro that particular file). |

Exomizer level option should indeed leave the non-packed areas untouched when depacking.
So my question is still open: Would it be allowed to just pack the whole memory with Exomizer or Pucrunch, even if after depacking the area $2800-$cfff is filled with zeros (which in a real life scenario would be the packed game anyway) and those zeros are left untouched when the intro is running?
If not allowed, still fine, it just shifts my focus a bit towards a field I'm not so much interested in. And there's hardly any gain or loss concerning the 8kb restriction, so it feels a bit of a waste of effort to me. In the end I might know about packers and depackers, tho. Good for picking up girls. :) |
