just stating some points that might help you.
1: if you are ripping the game from your disc itself, you should do it when your USB Loader Gx is set with cIOS 222 as the default IOS. If not, the game ripped will be a useless one.
2:For installing cIOS 222/223(either one to play SSBB) refer to
for installing Hermes IOS v5:
For installing Hermes IOS v4
You might want to check out the compatibility of your USB Loader before deciding to install either v4 or v5.
I use wiiflow R25 and therefore, only can install v4. I'm not sure about USB loader Gx.
3: When you are playing the game, change the settings of the USB loader to use ios 222/223 to play the game.
See if it works.
