Finally beat this game this past weekend. That song you get to play while the credits are rolling is insane! I also jumped online to test my skills and I managed to see Streex Rocks! across the screen a number of times. I finished my online session with a 7-3 record. I beat 42STARS on easy 2-0, beat THEGOD on medium 4-2, and split 1-1 with FLUUD on expert. I had a little trouble meeting up with people in this game, having to retry a few times when it came back with noone found. But I think that has to do with this being the older version of Guitar Hero. Most I'm sure have graduated to Guitar Hero: World Tour which I'm still without.
I did have some issues with this game that were weird and wonder if any of you have experienced them also:
1) The game wouldn't boot up. Troubleshooting revealed I had to disconnect my WiiSpeak accessory before the game would play.
2) The cursor on the menu would continuously scroll down as if I was holding the strum bar down, the whammy bar wouldn't work. Troubleshooting revealed a simple disconnect and reconnect of the WiiMote solved this problem.
I hope at the same time if any of you had these problems some of this info will help you out to get rockin' again.
