The limit is 4k, but the extra headers add only ~120 bytes to the memo. With
the headers I list above, and assuming 12 bytes per move pair ("10. Nf3 Nc6 ")
that still leaves room for over 300 moves! I personally have not had any games
with ChessGenius which have lasted beyond move 100.
My point is that many programs either require the seven PGN headers or function
better when all seven headers are present (such as databases which index on the
header values). Anyway, I have sent this bug to Richard. I hope he understands
the issue and implements true PGN export in the next version.
