Gaming Dragon Quest IX Garbled Text

[Skyline969]

So, I was playing some DQIX with my brother via wireless and we just best Lleviathan. Once we were done in that area, I noticed that a shop's text was a little garbled, but it went away shortly after. Once I got into the field and got into a fight, there was some more garbled text. It seemed to be happening at random, and didn't seem to affect gameplay. I quickly retired to the closest town and saved.... Has this happened to anyone else, and if so, how did you fix it? It's only ever happened to me tonight after I beat Lleviathan, so I don't know what's going on. Any thoughts?
