Well the omitted parts are repetitive case statements very similar to the
ones I left in. And the ones at the bottom are things like scores and have
been commented out (so to save space I left them out).

I put '\r\n' inside each of the cprintf(), and hey presto! - one long line
of darkgrey periods punctuated every now and then by coloured letters. Seems
like the cprintf() doesn't buffer (correct terminology?) the text until the
'\r\n' arrives at the end of the loop.  Removing the '\n' stops all apart
from output apart from text that is issued from within another module with
printf() - and that is coloured darkgrey.  I've tried changing colour and
using just printf() but that don't work, so why does it work when it is
exiting?

If you would like me to mail you the source, I could do that (I understand
that you aren't a debugging service), and to post more source would just be
an eyesore, since a lot of is repetitive switch/case statements.
