Hi,

Very interesting. (Very very pre-MMC, too.)
The graphics protocol reminds me of my first self-implemented pixel graphics
on a VIC-20.
It has nothing to do with CD-TEXT, except that it has to fit into the
same kind of 24 x 6 bit packets. It would be suitable to fill a few MB.
So its use in the program area makes sense.
Consider to fork a node "CD+G" from "CD Text". Both are only related
by the fact that they use the subchannels R to W for storing data.
--------------------------------------------------------------------
Looking at the commit diff of cd-text.texi:
Here you altered the technical statement:
Pack type @kbd{0x87} (Genre Identification) contains 2 binary bytes,
-followed by 0-terminated text. The two bytes constitute a 16-bit
-Big-endian number are decoded as follows:
+followed by an ASCII NUL. For category associated with Big-endian 16-bit
+value is given see @ref{table:categories}.
The NUL comes after the text which describes a sub-genre. You removed the
mentioning of this text.
(The sentence "For category ..." looks somehwat ill, too.)

-Pack type @kbd{0x89} is yet quite unclear. It might be a representation
+Pack type @kbd{0x89} (Second Table of Contents) not yet clear.
The verb "is" seems to be missing.

"not" is surplus and deceiving.

Have a nice day :)
