Had a great find (well, for me anyway) earlier today, at of all places, FUNCO!
For $2.99 apiece, each for Genesis:
Aero the Acro-Bat
Bonanza Brothers
Dick Tracy
Marsupilami
ROCKET KNIGHT ADVENTURES ( !!!!!!! )
And for the NES, Racket Attack for 89 cents. All of the Genesis games were boxed with instructions too. So happy, ROCKET KNIGHT ADVENTURES!
Total price: about 15 bucks. Sweet... Now I only wish I'd picked up one of the Nomads at CGE.
