I bought some cheap TDK DVD-R's but didnt work i burnt Okami onto one of the discs but dosent work so i was wondering if the discs are not compatible or if i burnt it wrong or the iso was no good
Its most likely that the DVDs aren't good enough for the wii to read. Go get Maxell or Verbatim DVD-R
could be a bad burn
or you got something edited on 3.3+
or a lot of things
Have you tried with a working backup disc first, and not one that you have made?
There is a possibility that you may have modded the wii wrong.
