Editing The Banner for Homebrew Applications:
Follow These Step:
1: First grab the homebrew application wad that you want to use. For me i will be using the Wad Installer Channel w/o banner.
Note: If you have an elf or dol file and you want to pack it into a channel search some tutorials on how to pack it.
2: Put the WAD you wish to edit inside the folder named “tools” and rename it to “in.wad”
3: Run WAD Unpacker.bat and it will create a new folder with the wad unpacked.
4: Double click u8extr.exe and click “Fichero”(File) and select 00000000.app file in the new folder created by the unpacker. It will create a new folder called 00000000_app_out.
5: Again, in u8extr, point it towards the banner.bin file in the new 00000000_app_out. It will create a folder inside “00000000_app_out” called banner_bin_out.
6: Open tplconv.exe, and click Leer Imagen” (Read Image) and find the image you wish to use for your banner (IMPORTANT: The image MUST be 590×332 pixels). *Use photoshop to convert image to 590×332 pixels if needed*
6.1: Now click “Guardar TPL” (Save TPL) and overwrite the file MenuScreen1.tpl located in the “timg” folder which is in the banner_bin_out folder.
7: Now, open the u8pack.exe and click “Abrir archiv” (Open File). Select the banner.bin file located in 00000000_app_out.
7.1: Highlight MenuScreen1.tpl and click “Añadir archivo” (Add File).
7.2: Select the MenuScreen1.tpl changed in step 6.1 and click “Sí” (Yes) to overwrite.
7.3: Under “Tipo de U8” (U8 Type) select “Archivo U8 firmado con MD5” (U8 file signed with MD5).
7.4: Click “Crear archivo” (Create Archive) and overwrite the banner.bin file in the 00000000_app_out folder.
8: Now, click “Abrir archivo” (Open File) again, but this time select 00000000.app in the unpacked WAD folder.
8.1: Highlight banner.bin and click “Añadir archivo” (Add File).
8.2: Select the banner.bin changed in step 7 and click “Sí” (Yes) to overwrite.
8.3: Under “Tipo de U8” (U8 Type) select “Archivo U8 con Banner Info con MD5” (U8 file with Banner and with MD5).
8.4: In the “Nombre canal” (Channel Name) text bars, you can name your channel to what ever you would like. (DO NOT touch the MD5 hash bar).
8.5: Click “Crear archivo” (Create Archive) and overwrite the 00000000.app file in the unpacked WAD folder.
9: Copy all the FILES (not folders) that are in the unpacked WAD folder (app, cert, tik,TMD, trailer) and paste them into the main folder “tools”.
10: Click the Wad Packer.bat and you should get a file called “out.wad”.
11: Install it on the Wii using Wad Manager or Wad Installer.
Change or remove the signatures of a banner:
Download 010 Hex Editor(Includes Keygen):
Rapidshare
Megaupload
1: Extract banner.bin with u8extr like you did above.
2: Locate banner.brlyt file in the folder Blyt.
3: Open it in a hex editor (010 Editor for example).
4: Scroll all the way down and look at the end lines of code; you’ll see a few words: “.. Banner by …… Image By….”
5: Now change those words to what you want (IMPORTANT: Do not alter the dots between each letter, as this will brick the channel) and save it.
6: Now, open the u8pack.exe and click “Abrir archivo” (Open File). Select the banner.bin file located in 00000000_app_out.
6.1: Highlight banner.brlyt and click “Añadir archivo” (Add File).
6.2: 6.2. Select the banner.brlyt changed in step 5 and click “Sí” (Yes) to overwrite.
6.3. Under “Tipo de U8” (U8 Type) select “Archivo U8 firmado con MD5” (U8 file signed with MD5).

Follow steps 7.1 through 10 for “Editing The Banner for Homebrew Applications” to finish off the WAD.
Change the icon:
Requirements: Previous knowledge of how to change the banner in tutorial “Editing The Banner for Homebrew Applications”
This uses the same steps for changing banner.bin, but now uses the icon.bin which is in the 00000000.app
1: In u8extr extract the contents of 00000000.app
2: Again with the u8extr extract the contents of icon.bin
3: In the Timg subfolder of the folder icon_bin_out there are 2 files to modify: IconImage.tpl which is 128×96 pixels, and LogoChan.tpl which is 112x32pixels.
4: Create two images to replace those two TPL files (IMPORTANT: One image MUST be 128x96pixels and the other 112×32 pixels. Faulty images will cause a permanent brick and cannot be restored without a modchip.)
5: Perform the same steps in Step 6 of the “Editing The Banner for Homebrew Applications” tutorial, only this time you have to overwrite the 2 TPL files.
6: Now, open the u8pack.exe and click “Abrir archivo” (Open File). Select the icon.bin file located in 00000000_app_out.
6.1: Highlight IconImage.tpl and click “Añadir archivo” (Add File).
6.2: Select the IconImage.tpl changed in step 5 and click “Sí” (Yes) to overwrite. (REPEAT STEPS 6.1 AND 6.2 FOR logochan.tpl!)
6.3: Under “Tipo de U8” (U8 Type) select “Archivo U8 firmado con MD5” (U8 file signed with MD5).
6.4: Click “Crear archivo” (Create Archive) and overwrite the icon.bin file in the 00000000_app_out folder.
7: Now, click “Abrir archivo” (Open File) again, but this time select 00000000.app in the unpacked WAD folder.
Follow steps 8.1 through 10 for “Editing The Banner for Homebrew Applications” to finish off the WAD. But instead of using the Banner.bin file, replace it with Icon.bin.
