Hello my dear friends...
Recently I downloaded Project M offline builder and then I created the Iso (Project M 3.5.iso). I want change the music of the game for play in my PC, but wii scrubbed 1.4 doesn't read the new iso file. How to do for fix that problem... exist another program for this? Thanks for your support...

Update
Continuing with my problem. I decided extract the files of the Project M 3.5.iso with dolphin emu. I replaced the files of music of the stages. Now, I need make/rebuild the Iso again. What program use for this?

Replace the files in the projectm folder of the iso builder then rebuild your iso.
