Ok, if you want textures for characters follow this directory:
[SD Card]>private>wii>app>RBSE>pf>fighter>[fighter character you want to put a texture in its folder]
for stage textures: [SD Card]>private>wii>app>RSBE>pf>stage>melee>[here]
*Gecko OS is for SD Cards with 2GB or less.
RSBE01.gct goes in the "codes" folder.
Make these folders in your SD Card.
Note: ">" means go into tgat folder.
Note(2): Names in the quotation marks are the names of the folder.
"apps"
"codes"
"private">"wii">"app">"RSBE">"pf">
***In the "pf" folder make a folder named "fighter", a folder in "pf" named "stage">"melee", a folder in "pf" named "menu2", a folder in "pf" named "module"
there's one more important one for common(#).pac, but I kinda forgot what the folder is named(probably "common"), since I haven't been on a computer in my house for this stuff in a few months, and won't get a computer til Christmas. But I'll help as much as I can, I guess.
