Hey, I'm following the video tutorial link and it told me to go into BrawlEx -> ExModules and not all the characters show up. Only Ike, Kirby copy, Link, Lucario, Lucas, Mario, Marth, Peach, Pikachu, Pikmin, Pit, Snake, Sonic, and Wolf. I tried re-downloading the file and the same few characters popped up.
Only some characters have ExModules they are still being worked on.
