I would like to know it too! When I tried to use OWM (Overworld manager) the pallettes became corrupted. I'm going to try some more things, I'll let you know my results.

Thanks a lot! But the import function doesnt work well. So I used hexmaniac to expand the amount of sprites en used OWM to import the png files. Now I have Rayquaza, Kyogre and Groudon in my fire red rom hack!
