🎁 Vintage Computing Christmas Challenge 2024 (VC³ 2024) 🎁

A small programming contest that will run from Monday, 2.12.2024 until Wednesday, 25.12.2024 

Submission is open! Check here.

The presentation of the entries will be some days after the submission, and it will be announced here.

The Main Challenge (Compo)

This year it's a  rather huge Christmas Present composed out of several characters.

   

The characters used are:

  • - Minus
  • + Plus
  • ! Exclamation mark
  • \ Backslash
  • / Slash
  • O Big O

All characters can be replaced with another character if this does NOT influence the code. E.g. backslash on the C64 gets replaced by chr$(205). Or on the right-hand side I replaced the big O by a smaller one, as it looks nicer, but it didn't influence the code. At any time, I could replace the o with O or the C64 Backslash with its counterpart on the C64.

Also check in the video above.
