File associations?

[Sparticus]

Okay, I have a problem with Dolphin that I was hoping to find a fix for:

I have a few .gcm files that I want to have windows associate with the Dolphin program that way I can just launch it from the file system. I tried to associate it with Dolphin.exe to see if that would work, but it failed. So I wanted to know: Is there a part of dolphin's file system that I can have the file associated with so that the game will launch when I double-click it?

after setting .gcm to open with dolphin you need to change the command in the registry from
"...\dolphin.exe" "%1"
to
"...\dolphin.exe" /e "%1"

Thanks a lot
