Hmmm...
To do:
Document the September 13th, 1993 prototype.

Not to be confused with MediaFire Maze.

Debugging File

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: Can this debug mode be reactivated in some way?

Present among the disc's files is cdi_mmd - a variant of the used file cdi_mm - which contains the code and strings for a debugging mode. It would've been controlled using a keyboard and a CD-i dev kit.

The file can be sorted into three distinct chunks. Chunk 1 deals with Mega Maze's gameplay itself, though there's not much here due to its simplicity.
