The intro text has already been translated, but it's so far off from the original Japanese that I figured I should redo it. Feel free to remove the references to "Pocket Monsters" but I think at least the character description should remain faithful to the original. Also, I couldn't find instructions for packing the text back into the game, so I can't check my line breaks. Hopefully they don't overlap.
I also translated the rest of the things in 0044, and the rest of the introduction which I can't find in the game file so I've attached it separately in case someone else knows where it is.
