I edited Professor Oak's sprite, and it doesn't appear when I go through the introduction sequence (the one in which he talks about the world of Pokemon)
When I revist unLZ the sprite looks like this: http://i18.photobucket.com/albums/b144/shirokiryuu/jiormenterror.jpg
=/ I'm not sure why....
You edited Oak's trainer sprite. The sprite in the intro is in unLZ but with dark colors. You have to insert your sprite over the one with the dark colors but it must be the same size and you mustn't export the palette.
