Up until now using Rock Band 2 DLC could only be done through the disc channel, because using a backup loader or a USB loader caused issues. But I read somewhere that with Hermes cIOS this was no longer a problem, and it was possible to play DLC songs in an SD card even when playing Rock Band through a USB loader. Is this true? If it is, which IOS merge should I use to do this? And on that point, which merges should I use for cIOS 202, 222, 223 and 224? Thanks in advance EDIT: oh wait the new Hermes cIOS doesn't have merges anyway is there really a way to do this?
