First thought is that you should buy a game with converter (ie a NES stackup) and turn this one into a total conversion (ie stick it in the nes cart with converter)...  You can even make yourself a nice looking label.

I've done that for Goonies, Bokasaku Wars, Devil's World, Milk and Nuts, etc.  Sometimes I've transfered the chips to US circuit boards rather than waste a converter, but I've also seen a much higher glop top percentage in famicom games (and ones that don't seem to be pirates). 

As far as just fixing the game, what's broken?  Do you have a pic?  Is there a hole in the cart and a post that goes through the hole?  Is that what's broken?

I guess I don't mind MTG, but my friends call me Michael... 

I'd stick a piece of styrofoam above the cart that's just the perfect size to keep the circuit board tight.  I'd cut the styrofoam to this shape so it keeps the cart from moving side to side too:

XXXXXXXXXX
XXXXXXXXXX
X                X
X                X

I'd probably put a piece of non corrogated cardboard between the circuit board and the foam so that that the circuit board doesn't just slice into the syrofoam.  Usually you can cut it with a sharp pocket knife.  Make sure it's pretty stiff styrofoam.  I'd cut it slightly big so that you can smush it and it will fith perfect for extra tightness.

Ok, hey you should send along that kid dracula too if you still haven't gotten it working!    Unless the mapper chip has died, I can fix most problems.
