With the prices of new games being greatly out of my reach, I thought I would try to make what I own look better on the shelf.  It is still a thrill when I find a manual I am missing, I usually get them from $6-$8.  I do not know if these are the manuals everyone is missing, so don't laugh too hard:
Turbografx-16
1.  Air Zonk
2.  Cadash
3.  Chase HQ
4.  Dead Moon
5.  Klax
6.  Neutopia II
7.  New Adventure Island
8.  Parasol Stars
9.  Raiden
10. Samurai-Ghost
11. Time Cruise
Duo
1.  Valis II
2. Gate of Thunder
EDIT:  Found a boxed, complete copy of Sonic Spike Volleyball.
