I recently picked up a huge haul at the yard sales... some of them super nice to the collection!

An old guy was selling a bunch of NES games- 5.00 each so I picked up all the unusual ones.

Quattro 4 in 1
Castlevania 1
Castlevania 2
Ninja Gaiden 2
Ninja Gaiden 3
Mike Tysons Punch Out
LOZ- 1
LOZ- 2 (darn it... gray cart here)

and the most important... most super fantabulous...... CONTRA FORCE.

I tested them all on a Hyperkin and they all play beautifully... except that stupid bootleg there. I don't think aftermarket bootlegs can run the unlicensed stuff.
