i have the custom characters im gonna use but how do i add them to the game?
Find a SSBB Riivolution XML, make a /ssbb/ folder at the root of your sd card, and place your hacks (recommended)
OR
Get the sd file patch code, make maybe a /private/wii/app/rsbe/ folder then place your mods including directories (ie X05.brstm goes /sd/private/wii/app/rsbe/sound/strm/)
I hope this helped.
