Connect Four (CD-i)

A Hasbro classic, now in video game form!

Debugging File#

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_cfd - a variant of the used file cdi_cf - 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 the Connect Four game itself, though there's not much here due to its simplicity.
