Rom problem

Helo i have just downloaded that game:

I have an R4 with an memory card kingston and a DS Fat.And i have an white japanesse text on my upper screen.
So i dont know if the probleme is the same than Worms 2 or another probleme.I think firmware update for all card like r4 must be doneSo help me please and thanks ;)

Up please , no solution? :o

Well we can't know really, it might be that a new firmware is needed yeah, but I can only guess.
