bleach versus crusade

i just bought the new bleach game but it is asking me for and upgrade in firmware. i currently have ntsc-u 3.3 firmware. i decided to try a backup using brick blocker but when the game starts i just get a black screen. i am using a wiikey2 with a d2a drive. should i upgrade to the latest avaliable firmware.

Update i just found some stuff about IOS and the IOS on this game is 55. I am trying IOS changer to see if it works. If not any one got a link on how to install them. I just have a wiikey2 and a 3.3u ntsc console. i would like to avoid homebrew channels becuase of the risk of bricking the console. i know its ironic ill crack it open and put hot metal to the insides but no software mods lol.
