My pirate collection barely gets any FC love, they seem to be the harder ones to find for some reason. Or maybe it's just the titles I want are rare? :) Here's a list of what I'm after at the moment, with serial numbers.

Donkey Kong 2 - NT-866
Donkey Kong Country 4 - JY-033
Earthworm Jim - NT855
Earthworm Jim 2 - Super Game version(has anyone ever even seen this version before?)
Super Donkey Kong -- Hosenkan Electronics Co., Ltd.
Super Mario World - 15 level version, boxed
The Super Shinobi
Tiny Toon Adventures 6 - JY-115, NT-6088, EL-002
Wait and See

I still remember first finding NES World over 10 years ago and being in awe of pirates. No doubt they were easier to find then! Any help, feel free to PM me, or post in here :D Thanks!
