I have a rather paltry collection of stuff. :c As of right now, the only pirated carts that I have are as follows:
Genesis/Megadrive:
-Top Fighter MK 2000
NES/Famicom:
-Pokemon Yellow (The ShenZhen Nanjing version, IIRC. I've never actually had a chance to test it, since I have nothing that actually plays Famicom cartridges :C)
GB/GBA:
A pirated copy of Pokemon LeafGreen that came in a gray cart, says "The save file is OK." every time I go past the title screen, and I cannot trade Pokes to other cartridges.
And technically, I have that Zone 60, too, if that counts as anything pirated/unlicensed. :y
Also, the first two were graciously donated to me (for a price, of course) by Barver, back when RX Community was still online. That was a good deal, I'll be honest.
I plan on getting other pirated Pokemon cartridges at some point, since those things pop up on Ebay literally all the time.
If I had a wishlist for pirates, though, I'd put Shi Kong Xing Shou on the list. I want that game so badly. ;^;
