Regarding audio

Well I’m using EasyRPG on my wii and I already read a thread about this right on this site, regarding sf2 soundfonts, but the og thread said I should put the Soundfont at the game that i wanted to sound better directory folder. My question is, does this also works with the wii, and If I paste a random soundfont at the folder of some game, will it play exactly like it? Or should I paste the sf2 archive elsewhere?

You must call the file easyrpg.soundfont and it must be in the game directory.

Must be in SF2 format.

It should also work on the Wii.
