Beginner's Guide to add ISO/WBFS to USB Drive

This guide is meant for the absolute beginner who has just softmodded their Wii and wants to add a ISO/WBFS file to their USB stick so they can play their games via a USB Loader app. The most common setup to play your Wii games via ISO/WBFS, is to have your all your HBC apps on your SD card while having your ISO/WBFS files on your USB stick.

- SD card that you already use that works for HBC
- USB Stick at least 4GB in size

- Softmodded Wii (Guide -
- WBFS or ISO file of game that you are wanting to add to the USB

Click on the large green Download button. You will be navigated to a new web page (still on After a brief moment, the download will begin..

Extract the download. You will see a folder called 'apps'. Move the apps folder to the root of your SD card. The SD card must be in FAT32 format. Place SD into Wii.

1. Insert your USB stick into your Computer.
2. Format the USB stick to FAT32 (Quick format will work)

NOTE if you use Linux and need to format a USB to FAT32: There is a program called 'gparted'. Simply google gparted FAT32, and you will find plenty of guides to format the USB.

3. Make a folder on the USB called "wbfs" (without the quotations)
4. Now we will make a folder within the wbfs folder. The name of this folder varies depending on the title and game ID of your game. For demo purposes we will use the American MKW game (game ID of RMCE01)
5. Within the wbfs folder, make the folder called - "MarioKartWii [RMCE01]" (without quotations)
6. The title of the game (no spaces) goes first, then the game ID within the brackets.
7. If your game is already in .wbfs format. We can simple drag and drop our American MKW game into the "MarioKartWii [RMCE01]" folder. If your game is in .iso format, please see further below for solution.
8. Once the .wbfs file has been added to the USB we need to rename it to match its game ID, so for this guide we rename the wbfs file to RMCE01.wbfs
9. Eject your USB. Now you must plug in your USB stick into the correct port. If your Wii is laying flat, this would be the BOTTOM port.
10. Launch HBC, launch USB Loader GX. You will see your game listed on the main menu. Select and launch it. Congratz.

If your game is in .iso format read this:
You will need WIT Tools to change the iso to a wbfs file. Download WIT Tools

For help installing WIT Tools, view this thread HERE

If you are on Windows:
1. Once the tools are installed, there is a new Wiimm folder within your Program Files (x86) folder of your C Drive. Within that Wiimm folder, is a folder called WIT. Drag your ISO file into that WIT folder.
2. Open up cmd/command prompt
3. Type this: cd C:\Program Files (x86)\wiimm\wit
4. Now type this: wit copy nameofyourISO.iso newnameofyourISO.wbfs
5. And that's it you have made a copy of your game in the better wbfs format. Now you can complete the rest of the guide.

If you are on Linux:
1. Once the tools are installed. Open a terminal in the directory where your iso file is located.
2. wit copy nameofyourISO.iso newnameofyourISO.wbfs
3. And that's it you have made a copy of your game in the better wbfs format. Now you can complete the rest of the guide.

If you get a black screen when attempting to boot your WBFS via USB Loader, there's a few reasons why this could happen:
1. Your USB stick is corrupted or near the end of its life. Reformat it to FAT32 (Do a FULL format, will take awhile)
2. Your WBFS file is corrupted, this could be because you possess a corrupt file of your game, or you simply pulled your USB stick out of your computer without properly right clicking on it and selecting Eject.
3. Your SD card containing your USB loader app is bad, reformat it.
