CFC japanese version

Yo!

I've bought recently
the japanese versions
of
Card Fighter Clash Capcom 'n
SNK editions....
as i opened the box i
saw a lot of things, but
i don't know for what purpose
i have to use the plastic thing which
came along.....

soes somebody know what i'm talking about?
are there diferent types of collecting
cards than the ones which came
with the game?

I saw only 2 differents cards:
-terry
-ryu

the plastic thing is for play with the wirless link.

yeah thanks!!!!!

so how do i use
the plastic thing???

i mean.. there wasn't any
discription i think....

you slide the plastic thing in the cart and after in the wirlesslink
