Cause your wii is not an LU64+ , using bootmii is the safest way!
(so your Wii's boot2 v2 Version)
It' can boot homebrew chaneel before system menu even thought your system menu is gone!
Some apps can patche the trucha bug back. (Trucha bug restoner, IOS 60 Patcher ,DIP-IOS etc...) Use these...
I tried this tool today!
I follow the readme.txt steps. Downgrade IOS 15 => patch IOS 36 ( all option switched yes )=> restore IOS 15
but it only patched trucha bug, no boot2 ,no ES_identify!
My console LU64+ (3.4V2J Taiwanese console )
Forget other IOS, notice the IOS 36.please!
BEFORE...
If you have a intel mac, install Windows by boot camp.
If you have a powerpc mac, install Windows on Virual Machine.(Vmware,qemu,VirualBox,etc...)
Or Try run MultiGameISOCreator.exe on Wine.
