Using codes with Dolphin

[PAVGN]

Somebody asked me about using codes with Dolphin. He said that he's using the latest Dolphin SVN build, And used WiiScrubber to replace all the files on the disc. The latest build of Dolphin has Gecko support but he can't see how to type any codes in, And without the codes Brawl Minus crashes at character select screen. I can't use Dolphin unfortunately, So I can't really help him with that. Does anybody know anything about using codes with Dolphin?

I use Dolphin but he doesn't support the code. He say :
Code Cleared Cache.
