Lots of questions

[Raycrash]

Ok guys I'm new to hacking brawl so go easy on me :P

The first question is whats the difference between pac and pcs ?
I somewhere read that pac is the moveset but isn't that a psa file ?

Then I wanted to know if it is possible to load stages/stage textures while the game is running.
As in adding new maps ? I know replacing is possible but can't I just replace a "custom map" (made in the editor) with a new stage from here ?

A PAC is used for changing characters or it's the file extension used for stages. They are also used in single-player mode. There are certain characters that NEED PACs, which are Wario, Bowser, Zelda/Shiek, and Samus/ZSS (correct me if I'm missing any) since they all transform at a point in the battle.
A PCS is what is at least needed to play with character.
You can't add textures while playing a game. As for stage editing textures, it will affect all of the textures of the same stage set.
That should help. Tell me if I missed anything.

Alternate Stage Loader lets you have multiple stage textures on one.

FitMario00.pcs = Multiplayer texture
FitMario00.pac = Singleplayer texture
FitMario.pac = PSA

Ok got that.
Where do I find the alternate stage loader ?

Oh and is it possible to play entire custom stages ? not just different textures ?

[dingo]

People usually make custom stages that replace normal ones...so I don't know what you mean. I don't have a link for the Alt Stage Loader at the moment.

Yes, people have been making entire nw stages that go over the original ones. Take the stage KC-MM VIP <-- that goes over 75M and it's an entire different stage then 75M is.

PAC is for Single Player Modes.
