I added the cheat on my CycloDS Evolution and got past the boat, so that was good. Thanks so much for the work, Narin.
But when I made it to the first town with the cave, I've come across another glitch. I don't know if it's anti-piracy or just a problem. I go into the cave and rescue the man from underneath the rock, but when I leave the room he reappears under the rock again. This happens every time. I also can't save at the church without the game freezing. Has anyone else had this problem?
