I was looking through the save for Guitar Hero III and found a way to edit the profile name for online use. This enables longer, uncensored names with punctuation allowed. For example, I made my username my e-mail address, so that if someone would like to play with me again, they can just send me an e-mail. To do this, you need the Save Extractor and Installer. After dumping the save to your SD card, you will find a file called PLAYERIN (WIISAVES\RGHE\NOCOPY). Open it with a hex editor and search for the profile name you want to edit. Add as many characters as you like, but take note of the semi-colon at the end. The semi-colon is followed by a small portion of hex that marks the end of the name. For me, it's "CD E7 01 01". I haven't yet figured out if it serves any other purpose, but take note that it has to be shifted down when you finish with your name. Use the Save Installer(it'll overwrite your current save) and you'll have an online name without restrictions. Enjoy.
