Do you have any PSAs? As I said, it can cause freeze on CSS for some reason.

I made a new torrent which I think will work (it seeds on my side this time):

Please remove the first one from the OP Sirkura

Also BJ, I have some notes on the STPM format that you might not know:

Header:
0x07 - Number of STPM entries. It is usually 01, but STGEMBLEM.pac got three entries in one (03).
0x10(4) - Is the offset to the entry, it's usually 14 but again Castle Siege is an exception, which has 1C.
For every entry, there's an offset to it in the header. For STGEMBLEM, this would add 2 extra offsets to the header.

Every entry is 0x104 (260) bytes. The first 4 bytes isn't a float value.
0x00 - Nothing?
0x01(2) - STPM ID (The first one is unique to the entry, the other one is unique to the stage itself)
0x03 - Echo (00 = false, 01 = true)

The rest of the entry is just float (64 values).

Here my notes along with the STPM files (and some other stage files that still are unsupported):

Ah, so that's what you meant. I have no idea if it's possible, and how (probably not).
Multiple people have been asking for extra color slots, but it just isn't possible for the time being.

please and thank you

Here:
I don't know much about this seeding stuff, I atleast hope I'm doing it right

EDIT: removed the link

If it's a certain character then it might either have something with their CSP (wrong format), or it might be a problem with some of their files (for some weird reason, I do have experienced a freeze because of an incompatible PSA). What region is your game? NTSC-U or PAL?

doing that would not make it a 1 slot

I thought so, or else it would've been done already

Well that's weird. If it isn't one of your characters that have a problem, and you don't have any hacks over Corneria, then I have no idea

Can somebody rip the THP's and put them in a zipped folder/rar? I'm doing a project, and I think PAL's resolution is larger than NTSC, but they still work on NTSC, as far as I know.

The movie folder is 3,31 GB, so I will have to make it a torrent file. Shall I upload it?

Is it freezing after the match ONLY if you're playing on corneria? If that's the case, then there's a problem with STGDXCORNERIA.pac. What kind of hack do you have over that stage?

Currently, that isn't possible.

what ur talking about is CLR0 editing... but ill check to see if his hair also has SRT0 too.

Not only is his hair changing color, but it's also moving.
Would adding CLR0/any other animation to the ModelData folder in FitCharacter0x make it color-animated one-slot, or would it simply not be loaded by the game?

ok i'll try it thnx

EDIT: what do i name the extra costumes.

Uhh... It loads the characters' alternate costume such as (example): FitSonic01, 02, 04 and so on.
It works for all characters, but I don't know if the code is very convenient though

BJ, I don't know if you remember, but I posted something about collision files some hundred pages back (page 167)

Oh, and I found out some information about collision files:

The 'Unknown 2' checkbox seems to only be used by the homerun contest barrier collision
(the one that blocks the sandbag and homerun bat, but not the players).
'Unknown 2' makes collision that works only for items.

'Unknown 1' makes it so that characters actually can interfere with the collision (as well as other things)
So if you uncheck 'Unknown 1', the collision won't work for characters.

Awesome Part:
If you uncheck 'Unknown 1', but check 'Unknown 2', the collision will work with only items  

To sum it up:
Unknown 1 = Collision for characters and everything else
Unknown 2 = Collision only for items

Unchecking them both makes a collision that only works for PKMN trainer.
Hope this may be useful

Are you still gonna add a drop-down box (or something similar) for it?

The only code I know is the on-the-fly costume switcher, which you find at this site:
http://www.geckocodes.org/index.php?c=RSBE01

It works for all characters, just change the button combination to your liking.
