I will need to credited if you use this hack for another one.
EDIT: Since I renamed HatN to Hat, you'll have to redo any animation that moves Mario's hat, and is noticible, like the taunt shown in picture 1. What I mean by redo, just export the HatN data inside the animation file, and add a new bone, rename that to Hat, and import the data file, and just mess a little with it to make it look better. If you don't, Luigi's Cap won't move. If you just re-rename Hat to HatN and mess with that data, you'll mess with Mario's Cap too. Doing this makes it so both Mario and Luigi's cap will move when he takes it off.
I know that LC ReSuRrEcTeD made a good port of Luigi over Mario, making so his face ISN'T jacked up, but I made it even better by making it almost flawless. LC ReSuRrEcTeD fixed Luigi's face by RENAMING bones, so thats what I did. You might be wondering whats different besides the texture, well this port has working hair! Luigi has a LHaveN and a RHaveN, since he doesn't use the left one, I renamed it to HairM and moved that before the HairMb and Re-renamed LC ReSuRrEcTeD's Luigi model's XRotN and TransN so they're flipped. Nintendo had made the polygon so if Luigi would've taken off his cap he wouldn't be missing half his head, but its never used in the final original game. Some of you might be wondering what led me to making this, and other probably don't give a shit about why I made it, if you one of those people then skip the next two sentences. I'm making a set of hacks that are related to Mario & Luigi: Superstar Saga, and I thought about using that Luigi over Mario port so they both have the hammer off of mariodk's SMBZ Mario moveset. But I decided to finout why Luigi's hat wouldn't move, and how he made his face look normal. And so the birth to this awesome port. Credit to ThatEarthboundguy for the texture that I used, it doesn't matter what textures, so use you're own if you want just give credit to me!! The pac and psc files have mariodk's cape animation, texture and model data, so if you just want the luigi model export the model data and put that in the FitMarioXX file you want and make sure you use Luigi's texture data, remember this is a Luigi model so he doesn't use Mario's textures. This port works excent with any Mario psa like SMBZ mario and maybe my own SM64 Moveset...
