Hi,
In Rock Band 3 [SZBP69], content to customize the characters as clothes, guitars, etc is unlocked via achievements, and some of them are really hard to get or need specific instruments (some even pro ones). Could it be possible to get every achievement, or if easiest, just the items it unlocks?
I have USB Gecko, but I don't know how to look for this.
Can anyone do codes for that or help me doing it myself?
