wait wait wait wat? What exactly is this alternate file patcher? I rlly didnt understand ur description. Where can I find this alternate file patcher? I'd like to look at it and try to understand it.
It's a code that lets you load an alternate texture or moveset by holding a certain button of your choice.
Example: I have all of Luigi's texture slots filled, but I want to use more textures. I hold Z while selecting Luigi and I can pick extra textures.
Example 2: I want to play as Lucario, then I want to play as the Mewtwo PSA, but I don't want to mess with the SD card. So, for one Brawl, I just select Lucario, and the next, I hold Z and select Lucario, but with the moveset.
Basically, it loads .pcs's and .pac's from a folder that isn't PF when you hold a certain button.
