Tekken Card Challenge

Well,well,well. It's a Tekken game,too,just with cards. This is for Wonderswam. It's a kind of console. The game is coloured,but on my emulator it runs in black & white and i think for everybody,too.
If anybody or everybody know this game,i don't tell the details.
The fighting styles are the same as in the Yugi-O cards.(Sorry if i spelled this wrong.)
But if somebody new on this forum,i tell something about the characters.

There are 21 characters in the game. Gon isn't in the game,instead of him Crow is the selectable. Doctor B. also in the game.

I think i have heard of this game...is it any good and is it worth that *** load of time and hard work it takes to get the damn PSX emulator to work?

it's not for PSX,it's for Wonderswam,which is a console.
