The 63 in 1 cartridge pictured below is awesome for one reason:
the label art. Check it out! There's the
Ghostbusters with their equipment in hand, crouched
a bit, ready to take on the demons that soar above
them. The orange curtains sweep in as two flaming
white horses gallop by. Wow.

Pirate cart art does not get any better than this!
Aside from the label art, this is your typical
multi-cart -- typical because it's got all the games
you'd expect on a multi-cart. Surprisingly, for
focusing so much attention on Ghostbusters, this
cartridge doesn't have a Ghostbusters game on it. So,
the pirates lied, which is nothing new. But damn
them! Would have been nice to play some pirated
Ghostbusters!
Expect to pay anywhere from $7 to $25 for
multi-carts, depending on the number of games
indicated by the label. This one was part of a
rather pricey pirate lot. It'd probably go for $15
on eBay, but the same cart below, without a label,
wouldn't get but a couple bucks.
Here's the games list:
