I agree with Nano. It may be a small mod, but it is still using assets from something that isn't theirs and making money off of it, all the while having a false download link that just promotes something else of theirs.

Nice job! So, what core files are you talking about?

I downloaded a Dr. Luigi skin http://forums.kc-mm.com/Gallery/BrawlView.php?Number=202964 and it came with two textures named MarioPill1 and MarioPill3. How would I make only that Luigi skin shoot pills instead of fireballs? It also came with a FitLuigiMotionEtc file too. Dr. Mario is a skin in Project M that shoots those specific projectiles, so couldn't I make the Dr. Luigi one do that too? And if possible, how could I make the sound be the one when Dr. Mario fires a pill just for that costume? There was no FitLuigi.pac included, just FitLuigiXX.pcs, FitLuigiXX.pac, FitLuigiMotionEtc.pac, MarioPill1.png, and MarioPill3.png. Thanks.
