Sounds reasonable.

Theory: The file type could be a bit field with two bits, with
1/0 meaning copy protect on/off and 2/0 meaning game/data. I can't
test this theory though as my DC isn't networked.

As for $66/$67, $7000 and $dd00 looks like file sizes. Is it the same
as in $68/$69?

bit 6, 3 and 2 are no care, so $cd is the same as $81.

$4d is the same as $01. That's the first time I've seen someone use
the half-speed mode... :-)
