hi, i hope you can help... i picked this up in thailand a few years ago,  its "118 in 1" - 118 games on one GBA cartridge with "no repeats". amazingly, it works fine! i'm wondering if it has any value? i couldn't find any sold on ebay or anywhere else though, so i'm assuming its "grey".. the games include:

Pokemon Chaos Black
Super Mario Advance 4 (aka Super Mario Bros 3)
Mario & Luigi Superstar Saga 
Spy vs Spy
Galaxian
the entire Donkey Kong series
the entire Pac Man series
Excite Bike
Dig Dug
Arkanoid
Tetris 
Karateka
Bomberman Tournament
Space Invaders

... and all the rest can be seen in the picture(s) of the back of the box below:

Pirate carts are so cool. No idea on value of this one, but I have seen 100+ games in 1 sell for about 50-70 bucks.

If those sell for $70, I got chunk of cash sitting here.

That should not get more than $30 but people are dumb.

I have a couple of these same carts and a load of GBA bootlegs. Not sure of value probably $15-$20 for the multicarts.
