Notes:
Note #1: Edits are not noticed, most likely being due to the Brawl developers making common5_en.pac be the superior file.
Note #2: Edits are not noticed, most likely being due to the Brawl developers making Info_en.pac be the superior file.
Note #3: There are two files for each of these files, but are named differently (Example: Info_en.pac and Info_mg_en.pac). Both files have the same contents, but the mg files are larger in file size.
Note #4: Both duplicate files must be modified in order to have your character's name to be in-game for Classic, All-Star, Boss Battles, Target Smash, Event, Multi-Man Brawl, Homerun Contest, Training, and Multiplayer modes. Otherwise, your character's name will not appear in certain modes.
Note #5: mu_menumain_en.pac is the superior file over MenuMain_en.pac. Editing MenuMain_en.pac seems to have no effect in-game.
Note #6: sc_sel_event_en.pac is the superior file over event_list_en.brres. Editing event_list_en.brres seems to have no effect in-game.
