You are trolling now.
This ( GBA temp )is the best place to get help for softmodding your Wii.
For modmii I can only say it is the best windows application to get you all the files needed to softmod your Wii.
MAKE SURE YOU ARE USING THE CLASSIC VERSION, NOT THE GUI VERSION.
A big plus for newbies is that is comes with a PERSONAL GUIDE, depending on your given options. And is is fully offline.
By wich I mean when you are hacking your Wii it will be done offline, so there's zero chance of your Wii bricking in the case of terminated services.
Modmii is a very, very deep deep batch program, even up to building your own custom slots containing any pathed ios.
After your basic softmod you can use modmii to build your custom nand for use with Uneek/Sneek and various usb loader that have implemeted nand saving and channel loading. Use it to install diosmios/nintendont, custom themes, etc etc.
This only scrathes the suface of what Modmii can do, and did to the softmod community.
Rmember the author of Modmii , XFlak has been closely involved in the developeing the holy grail of Custom ios, Named d2x.
This cios alone gives compatibilty to about 99% off all surfaced Wii games, and channel loading.
Also the fact that the sheer amount effort that has been put into modmii to make it the safest, easiest and foolproof batch (!) program for new users.
Just tell modmii you want to softmod your Wii even when it's been (poorly) been softmodded before, and follow along the genereated guide.
For us experienced users, you can go the manual way offcourse, and pick your files from modmii's abundance of options.
Getting the right tool for the job is half the work they say, modmii saves so mucht time fetching the proper up to date files.
Instead of getting themfrom somtimes not so thrustworthy sources, never knowing sure if the are "really" what they say they are.
The files modmii gets are 100% legit, otherwise you will not get them via modmii ( safety precaution via hash checks ).
Rest assured.
The only gripe I have with modmii is that is does not come with USB Loader GX, wich is in my opinion the best , most complete easiest ( every option is logically locally reacable from it's Wii like gui, no ini editing needed etc. ) usb loader. Nintendont ( Gamecube usb loading ), nand dumping ( copy of your Wii's file system for hereafter mentioned functions and options ), Nand channel saving ( savegames on your USB or SD card intead of your Wii ), Channel loading with official banners, ( Wiiware, virtual console etc from your harddrive ) covers, banners and arrt work can be downloaded by clicking on the "?" dvd cover, parental controls, and so on and on, barely scratching the surface.
Use modmii by XFlak for WINDOWS to get your files the easiest safest way, if you want to softmod your Wii.
