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_cmtd - a variant of the used file cdi_cmt - 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 files were updated in the 1992 revision, with cdi_cmtd in particular having many strings added, removed, or rearranged.

Its contents can be sorted into three distinct chunks. Chunk 1 deals with the various modes of Children's Musical Theatre, though there's not much here due to the game's simplicity.

Finally, Chunk 3 has the CD-i graphics editor/second chunk-esque strings prevalent among the debug files of CapDisc's games.
