Yellow cartridge = late pirate.

One of the things to note about this pirate is the yellow cartridge. Early pirates almost never are yellow cartridges. It wasn't until the late 90s that pirates began showing up as yellow cartridges. I don't know why, but these yellow cartridges, which exist in massive numbers, are a mixed bag; sometimes they have really awesome games and sometime they contain the licensed version of a game close to the title of the pirate. For instance, Rockman 7 is Rockman 6.

Yellow cartridges also tend to be lightweight because the boards are "glob-tops," which is a black resin placed over a small chip. These types of boards have a higher rate of glitches than normal boards with large chips and no globbing.

This pirate came as a part of a lot from eBay and wouldn't be worth but a couple of dollars. But sometimes it's worth picking up a lot of what looks to be crappy pirates, just to see if you get something worthwhile.
