There's an EOS update for the Supercard DS One users that allows to play this game in patch mode (haven't tested with the EUR version tough, but if the ap is the same, it might work). The patch can be found here (Supercard forums): http://forum.supercard.sc/thread-5524-1-1.html
It's a ds1patch.dat file, so it goes in the _dsone directory, it should overwrite the old one.
