🎁 Vintage Computing Christmas Challenge 2025 (VC³ 2025) 🎁

A small programming contest that run from ?.12.2025 until ?.12.2025

 

In planing.

 

The Main Challenge (Compo)

This year it's a  ... composed out of several characters.

   

The characters used are:

• ?

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.
