@cj iwakura: shame on me. I read your post sure 10 times since you posted it but i always forgot to answer or had any problems answering like when from my mobile. Anyway, there is only text editing/insertion left and maybe some memory managements to correct for the game.
I don't know if you are interested in those things or if you have experience in NDS asm.
Drop me a PM if you are still interested and sorry for the late answer.
@All others: thanks for the support and I take the occasion to confirm the case 1 patch for Christmas.
