setting up textures

[Mr Physych]

im sorry if this is a noob question but i have been looking around and im still trying to figure out how all of the parts of texture hacking works.
i understand how to setup the pcs files and i can get texture on the characters while fighting but i dont understand what pac or tga files are and where they are put. Also how do you set up the selection portraits, do they go into the same file directory or do they have special directories (all these are with premade textures, as of now im not really planning on making custom textures myself.)

ya well now i figured out the meowmix stuff but so far im still confused about where to place the edited .tga files. when i put them in the newfiles folder and use step2.bat it doesnt create a system folder. and right now im also having trouble getting brawl+ to work but ill figure that out
