I wrote this email to my friend who asked the same thing the other day, it might be a little out of context but it should get you up to speed in a couple of minutes. It's very opinionated but I have no desire to use 'Configurable USB loader' because it's not as pretty as 'USB loader GX'
Copy/paste follows....
You get
http://bootmii.org/download/ and chuck it on an SD
64mb should do the trick. Maybe even 32mb
That installs:
DVDX - allows burnt discs to read
Homebrew Channel - Adds a channel where you can lauch any application placed in SD:\apps\appname\boot.elf (or boot.dol)
BootMii - Either installs as an IOS or as Boot2 (installer will tell you which it's doing) - allows you to back up the whole Wii's NAND (requires 1gb SD card)
That gets you running 'questionable' content like emulators (snes/n64/mega drive/arcade/commodore64 etc) and media centre software.
To get full blow pirated wii titles running there's a few more steps
First you need to install what's called the truncha bug, it's a security loophole that lets you install whatever you want really.
http://filetrip.net/f7484-Trucha-Bug-Resto...MOD-source.html
you might need these files in the root of the SD too
IOS15-64-v257.wad
IOS15-64-v523.wad
IOS36-64-v3351.wad
IOS37-64-v3869.wad
you can get those on the PC by using a program called NSUD (
http://wiibrew.org/wiki/NUS_Downloader )
you basically click 'Database' then 'IOS15' then 'v257' for the first one for example
make sure you have 'pack wad' ticked, as well as 'decrypt contents'
nb. decrypt contents requires common-key.bin to be located in the NSUD folder. ShowMiiWads can make a common-key (
http://wiibrew.org/wiki/ShowMiiWads ) (it's in the tool menu up the top, Create Common-Key)
So once you have those files on the SD you run Truncha Bug Restorer from the Homebrew channel you installed earlier
then do the following
Downgrade IOS15
Install IOS36 with patches
Restore IOS15
Once that's done you can install a USB loader and what's called a 'custom IOS' which will read files from the USB
You want USB Loader GX version 921 (http://code.google.com/p/usbloader-gui/downloads/list?can=1&q=921&colspec=Filename+Summary+Uploaded+Size+DownloadCount )
There's two there, the Wad and the Dol. You have a couple of options here:
You can throw the dol into the apps folder on the SD and run it from there, that's safe and easy.
You can do the same and also install* the forwarder
http://usbloadergx.koureio.net/downloads/forwarders
You can outright install* the wad onto the Wii and you won't need an SD sitting in there 24/7
*to install Wads you need to use
http://teknoconsolas.tv/wanin/WAD-Manager_v1.5.zip which goes in the app folder, the wads it will be able to install are kept in "SD:\wad" so for eg. you'd put 921.wad into that folder
Wad manager asks which IOS to use to install wads, you want to choose IOS36 - remember we put the exploit in this one in the previous step
Now you need a custom IOS to be able to run all this jazz. Hermes is the best one, v5 has a bug which prevents you using FAT32 or NTFS on the USB drive so you want v4
http://filetrip.net/f8367-hermes-cIOS-2222...nstaller-4.html
It gives you a lot of options on how to install, generally you're best off putting a merge of 37+38 onto slot IOS222
It's a little weird to look at the installer, it asks which slot to use first, (222) then which IOS to use as a base (37+38)
at the start it might also ask which IOS to use to install (similar to wad manager earlier) you can just use IOS36 which you've patched.
Once all that's done you just need to pop the games into USB:\wbfs\gamename.wbfs and load up USB loader GX and the games should appear
some games need a little tinker with the options but 99% of games run straight away.
You'll also find a lot of games you download are still in ISO format, obviously so they can be burnt. To convert them to wbfs you want to use Wii game manager (http://www.megaupload.com/?d=D0MBCKAA) on the PC, in which you just open a folder full of ISOs then right click and convert to WBFS
I don't have a lot of experience with playing burnt discs instead of USB-loading but you'd use NeoGamma (
http://www.mediafire.com/?zjytnnjryyn ) there's more info on it here
http://gbatemp.net/index.php?showtopic=158884
It probably doesn't need the custom IOS so you could get away with only following the first part of this guide (the green bit) and then throwing neogamma into the apps folder on the SD
