'Kay, so I've been using Gecko through Balanced Brawl for a while now, but I can't replace any SFX with it. I've heard that Riivolution can, but I don't want to mod my whole Wii console. So, I've seen that it is possible to use Riivolution without modding the Wii, but I was curious, would I still be able to replace SFX if I use the SD card instead of modding the Wii? Thanks in advance.
