I am working on some youtube videos following the history of the Earthworm Jim franchise and have decided to do an video dedicated to the NES pirates of these games. However, information on pirate games seems to be very difficult to come by. So I've decided to come here and ask or help. I have discovered three Earthworm Jim pirates for the Famicom:

Earthworm Jim 3 (a port of the original EWJ)
Earthworm Jim 2 (also called EWJ 4, a port of EWJ 2)
And a very strange game called Happy Biqi 3 Which seems to be a romhack of Earthworm Jim 2

I need to know if any other Earthworm Jim pirates exist. If not, I'd also appreciate knowing what companies released these games and what countries they were originally sold in. I've heard that some of these games also came on multicarts with other games. If this is true, I'd like to know what kind of carts and what the other games were. And finally, I have failed to find ANY information on this "Happy Biqi 3" game other than it existing. Any info on this game would be a huge help, including where it was made and by who (and maybe for what reason). The name suggests that it's part of a series, or at least was hacked to look as such, but I can't find any info on a Happy Biqi  1 or 2, if those games even exist. Finally, if it is allowed, I'd like to know any websites where I might be able to find ROMs of these games (Especially Happy Biqi 3).

Thanks for the help!
