Just spent a bunch of money on some instruction manuals to complete some games.
Blue Marlin
Blues Brothers
Fisher Price: Perfect Fit
Indiana Jones & The Temple of Doom
Kung Fu
Mendel Palace
Metal Mech
Metal Gear
Sky Shark
Super C
Super Spike V'Ball
Super Spike V'Ball / Nintendo World Cup
Tecmo Cup Soccer
Tecmo Cup Soccer was the only one that broke the bank ($25), pretty much everything else was $2-$3 except for the "popular" games (Metal Gear, Super C, etc).
