I burned a d/l iso of Mad World. When I inserted it I was asked to update. I declined the update and ejected the disc.

My question is how might I determine which version the d/l iso is ex. pal, ntsc, jap etc.....

I have not performed any soft mods. My drive key is default set to block import updates but I'm not sure if this will protect me from f-ing up my wii.

I apologize if this is a duplicate thread. I searched and either I'm too lame to find it or it isn't worded quite this way.
