I have a pirate of Ulitmate Tiger, that is a standard Hucard, with the label on the spine saying PC-Card PC-E GAME NO.3.  The booklet unfolds, rather then opens like a normal booklet, & there's some very basic pics & info on how the game works, & about the stages on either side of the unfolded booklet.  And there's no copyright info anywhere!  But, like I said, it's a regular Hucard, works perfectly, comes in a Hucard slip & everything.  I got it off ebay awhile back, not knowing it was a pirate until I got it.  I always did think it was wierd saying PC-E game, but didn't totally think about it being a pirate until now :oops:
And now that I think about it, I think it was shrinkwrapped when I got it.  And I'm looking at the back of the card, it say PC-CARD, then a bunch of Japanese stuff, then some notes of what not to do to the card, in english, & finally KING & some japanese.  And looking at the original at PCECP.com, I can see they removed the top left HE System PC Engine, but putting a small picture of the snake from the front cover, colored pink.  And the entire bottom half of the booklet has a red bar, covering up Taito's info.
