Wii system menu crashes

[DefenderX]

i don't think so. for me, ShowMiiWads is very easy to use ^^

first of all, goto "View" and check "ShowMiiNand". After that, goto "Options" and "Change NAND Backup path". (of course to your decrypted nand in Dolphin/User/Wii).

and now, you can drag n drop your WAD into the window and the tool will install it.
