Err... you don't need FitPikachu00.pac, FitPikachu00.pcs, FitPikachuMotionEtc.pac at all.
Only FitPikachu.pac handles the moveset, So it is either a faulty PSA or Code...It may even be the region your trying to play it on
How will the PSA work without a MotionEtc.pac to give it its animations? Won't it act all weird? Also, without the .pcs file you won't be able to load it over any texture you want but it isn't necessary you're right. I probably should have said that.
You seem to have quite big misunderstandings on how these things work. If there's no motion.pac in the folder the game will just load the default motion.pac from the disc, same with the models/textures.
So unless the PSA comes with modified animations there's no need for a motion.pac.
For the actual problem at hand, it's probably a code related issue. Faulty File Patch Code or just simply the wrong region.
Looks like a problem with the shadows. I had that with an imported castlevania stage, even after deleting all traces of shadows in materials/textures they would still show up in a weird way.
Unless someone knows how to fix that, you're out of luck =/
I said I was disappointed, that's not an insult, at least not where I'm from. I'm merely stating my opinion.
Project Pichu is dead, the only thing going for him is Dantarion claiming to work on a Project M version that will play like "a mix of Pichu and a forumtroll".
Meh, I could go on but I don't want to derail this topic anymore. In the end Beyond can do whatever he wants anyway.
Also I finally found a good stage for that one video I promised to make. I'll get started on it once I find someone who can do a detailed voice description for Frog and Magus >.>
