can i hack the iso?

[Zongalito]

Well, my wii reads pirate disc, and i don't know how to install usb loader (plus, i don't want to)
so i can't use riivolution, and with codes i can put new sounds for voice for character
so... i have a question
i can hack de brawl iso, to replace the sound files? i have already the sound file which has shadow voice for donkey kong, but i need to know if this will work, if the iso will load or stuck into a black screen?, if this is safe or this can brick my wii?
thanks for read
sorry for my bad english

I've only been able to run custom ISOs with a USB Loader.  Now, you don't have to install a USB Loader at all; you can just load it, via, the HBC.

Yeah just use Neogamma to load the disc. And yes it's completely safe. But if you dl a lot of games you might want to consider using Usb loader (it saves you money in the long run)

depends on his firmware version, after 4.1  can't install cIOS without downgrading it wich is dangerous and i only did it because my wii was broke and wouldn't play discs >.> how ever if u want to instal one i can help i have experience with loaders
