I downloaded the Dark Wii Park theme from the Wii Team Creations Thread and it was in .mym format, googled a tutorial to convert it to csm. Found a tutorial on WiiHacks: http://www.wiihacks.com/wii-custom-software-hacks-applications/53685-theme-any-3-2-4-0-4-1-4-2-wii-thememii-mymenuify.html I found MyMenu from another source in a zip, I think it was complete softmod guide. I used 007.app for 4.1 as my base. I downloaded it from ModMii. Opened MyMenu, added the files, clicked create mymenu, just as soon as I click the button, it returns w/ U8: Unpack Fail. Any ideas how to fix this? Should I use ThemeMii? I read in the WiiHacks tutorial about making a common key and the zip w/ My Menu had a executable called MakeKeyBin. What is a key & what does it do? Thanks.
