Rules

  • Do not reveal the code or even the exact size of the code to anyone. This shall be a personal challenge.

Format

  • Submit the following within one zip file:
    • an image (screenshot) of the result (of the object) [e.g. result.png]
    • Runnable file (e.g. compiled assembler code, BASIC file that runs on host, a.s.o.) [e.g. star.prg, star.bin, star.com, ...]
    • Source code:
      • source code as readable text file (e.g. BASIC code, assembler code, etc.) [e.g. source.txt]
      • an image of the source code listed (on the native machine or on the machine coded); can be integrated with the image of the result (optional) [e.g. source.png]
    • file_id.diz:
      • see next chapter below
