Depends on how new your wii is.
The Newer Wii's can’t Boot games through DVD with Neogamma. They can only boot games through USB of a Hard Drive using Neogamma Wiiflow, or usbloader gx ect...
The older Wii's can boot games from DVD with Neogamma
If your not sure what you have its really simple just try it. It will either work or not.
What you need is:
NeoGamma
cios installed for example

and a DVD
Now I have been away from the sence for a while but if memory serves me right all that should be accurate. Also personally i would't bother with brick blocker as most apps like NeoGama, usbloader gx block updates anyhow.
