1. Go to
http://modmii.comuf.com/ and download ModMii.
2. If you have used ModMii before then delete all the files in your COPY_TO_SD and COPY_TO_USB folders so that you don't accidentally copy over files from another install and accidentally install them. If you installed ModMii into its default path then you can find those folders in C:\ModMii\COPY_TO_SD and C:\ModMii\COPY_TO_USB.
2. After it's installed and/or you've deleted the files in the above folders then open up the regular version of ModMii. Not the skinned version. (Just personal preference and is what I use.)
3. Type "I Agree" (without the quotes. None of the things I will tell you to type will need the quotes) and press Enter.
4. Type "O" and press Enter to go to options.
5. Make sure that that it says "<Enabled>" next to "n20 = neek20 - build mod of s\uneek instead of original". (It should be by default.)
6. Type "M" and press enter to go back to the Main Menu.
7. Type "S" and press enter for "SNEEK Installation, Nand Builder, and Game Bulk Extractor"
8. Type "1" and press enter for "SNEEK Installation".
9. Type "1" and press enter for "96 (hosted online).
10. Type "UD" and press enter for "UNEEK+DI"
11. Type "D" and press enter for "Default Setting: COPY_TO_SD".
12. Type "D" and press enter for "Default Setting: COPY_TO_USB".
13. Type "Y" and press enter for "Yes, do it now!"
14. When everything is done you can exit ModMii.
15. Now go to your "COPY_TO_USB" directory which should be located at "C:\ModMii\COPY_TO_USB" and open that folder. (Ignore the COPY_TO_SD folder. You don't need it).
16. In that folder you will see a folder named "SNEEK". Copy that folder to the root of your USB drive. (if you were to look inside that folder you should see 4 files. di.bin, font.bin, kernel.bin and rev.txt).
Done
Now that is done you need to do one more thing to make it so USB Loader properly exits neek mode EmuNand back to Regular NAND:
1. Now go to "
https://code.google.com/p/custom-di/downloads/list" and download one of the 4 wads that have NK2O in them. Me personally I downloaded the one that said "neek2o_NK2O_1.wad"
2. Place that file anywhere you want. Preferably the root of either your SD card or USB drive.
3. Open up USB Loader GX.
4. Click on the gears on the lower left to open up "Global Settings".
5. Click on "Features".
6. Scroll all the way down and click on "EmuNAND Wad Manager"
7. Click on "File"
8. Then go to where you have the WAD file and install it. When done you can delete the WAD file.
Done.
Now when you exit a game loaded in neek it will exit back into real NAND.
And that's it. You just now compiled neek2o and "installed" it onto your USB drive. Just make sure that your EmuNand is also on your USB drive (I have heard neek2o works better from USB). Now all you have to do is change your settings to have your WiiWare and Virtual Console games load up using neek. I would recommend doing this on a per game basis. To do that you would want to do the following:
1. Click on the game you want to play.
2. Click on "Settings".
3. Click on "Game Load".
4. Scroll all the way down until you see "Nand Emulation" and change it to "Neek".
The only thing left to do to make exiting neek more seemless would be to install the USB Loader GX Forwarder into PriiLoader so that when it reboots the Wii it automatically loads back into USB Loader GX. If you need help with that let me know and I can write you a step by step guide for that as well.
