| ==(FTP Method) Dumping your games, updates, DLC's or transfering saves==
| |
| '''<big>Prerequisites:</big>'''
| |
| :* An SD card and a way to put files on it (if your PC doesn't have a SD card reader, you could use a laptop that does have one).
| |
| :* A homebrewed Wii U while being able to launch (see https://wiiu.hacks.guide/ for a guide on how to do this). Just make sure that you know how to launch Mocha CFW or CBHC (Coldboot Haxchi) and go into the Homebrew Channel.
| |
| :* Enough space on your computer to store the games on.
| |
| :* If you want to dump physical games, you'll need to have that SD card that you use above be 24+ GB or have a seperate USB stick that's FAT32 formatted.
| |
| :* Have [https://filezilla-project.org/download.php?show_all=1 FileZilla] installed on your PC.
| |
| <br/>
| |
| You'll also need to place a few files on your SD card. Choose the steps according to which method you use:
| |
| :* If you use CBHC (Coldboot Haxchi):
| |
| :::* Download Disc2App from https://github.com/koolkdev/disc2app/releases/download/v1.0/disc2app.zip and place <code>Mocha.elf</code> into your <code>SD:\wiiu\apps</code> folder.
| |
| :::* Download FTPiiU Everywhere from https://github.com/FIX94/ftpiiu/releases and place <code>ftpiiu.elf</code> into your <code>SD:\wiiu\apps</code> folder.
| |
| | |
| :* If you want to use Mocha, you'll need to install some alternative files:
| |
| :::* Download Disc2App from https://github.com/koolkdev/disc2app/releases/download/v1.0/disc2app.zip and place <code>Mocha.elf</code> into your <code>SD:\wiiu\apps</code> folder.
| |
| :::* Download FTPiiU Everywhere from https://cdn.discordapp.com/attachments/526469047890739220/542145496374837250/ftpiiu_everywhere.zip and place <code>ftpiiu.elf</code> into your <code>SD:\wiiu\apps</code> folder.
| |
| | |
| ===Steps for Physical Disc Games===
| |
| ====Dumping the game to your PC====
| |
| :* Remove your Game Disc from the Wii U, Disc2App will ask for it later.
| |
| :* Insert your SD card back into your Wii U.
| |
| :* Open the Homebrew Channel.
| |
| :* For CBHC (Coldboot Haxchi): Run Disc2App.
| |
| :* For Mocha: Run Mocha CFW '''first''' and let the Wii U restart. After that, try launching the Homebrew Channel again, and '''now''' run Disc2App.
| |
| | |
| [[File:Disc2App.png|550px]]
| |
| | |
| :* Select either SD or USB to dump your game discs on.
| |
| ::: Again, make sure that 24+ GB free on your SD card/USB stick. And if you use an USB stick make sure it's FAT32 formatted.
| |
| :* When asked, insert the disc for your game.
| |
| :* The game is dumped to <code>SD/USB:\install\[TitleID Folder]</code>
| |
| :* After it finishes, dump your next game or press home to exit and turn off your Wii U.
| |
| :* Now, eject the storage device you dumped your disks on and access the SD card or USB stick.
| |
| | |
| :* You can rename the [TitleID] folder of each game to the name of the game and move it to some folder you want to store your games in.
| |
| ::: You can find the game's title ID on http://wiiubrew.org/wiki/Title_database#00050000:_eShop_and_disc_titles.
| |
| | |
| ====Decrypting your game====
| |
| :* Download Cdecrypt v2.0b from https://cdn.discordapp.com/attachments/526469047890739220/539529151095373824/Cdecrypt_v2.0b.zip .
| |
| :* Extract the zip and go to that folder. Copy the same 3 files from the folder into '''all''' of the dumped game folders (or only 1 folder if you've dumped only 1 physical game).
| |
| :* In each of the folders you've copied those files to, hold down CTRL and select both <code>title.tmb</code> and <code>title.tik</code>.
| |
| :* Drag those 2 files onto CDecrypt_v2.0b.exe which will decrypt the game into <code>Code, Content, and Meta</code> folders.
| |
| :* You may now delete all files except the folders <code>Code, Content, Meta</code>. And now repeat the steps until you've decrypted all of your physical dumps.
| |
| :* Now that you've got the base game, there's likely some updates available or you want to add some DLC's you have on your Wii U.
| |
| | |
| ===Dumping downloaded games, updates and DLC===
| |
| :<code>Make sure that your Wii U is connected to the same network as your computer and make sure to update your game to the latest version.</code>
| |
| | |
| :* Insert your SD card into your Wii U.
| |
| :* Open the Homebrew Channel.
| |
| :* For CBHC (Coldboot Haxchi): Run FTPiiU Everywhere.
| |
| :* For Mocha: Run Mocha CFW '''first''' and let the Wii U restart. After that, try launching the Homebrew Channel again, and '''now''' run FTPiiU Everywhere.
| |
| :* On your screen, you should be able to see a line "Listening for data connections at xxx.xxx.xxx.xxx:XXXX". Note down the text at the end with the numbers in it.
| |
| <br/>
| |
| | |
| :* On your computer, open FileZilla.
| |
| :* From the <code>File</code> menu in the menu bar, open the <code>Site Manager</code>.
| |
| :* Click on the <code>New Site</code> button.
| |
| :* Now, you'll want to fill in the Host and Port field.
| |
| :::* In the Host field, put in the longer <code>xxx.xxx.xxx.xxx</code> part you noted down.
| |
| :::* In the Port field, put in the rest of the numbers of that thing you have made a note of, represented by the <code>XXXX</code>.
| |
| :* Go to the "Transfer Settings" tab and click the checkbox to enable the "Limit number of simultaneous connections".
| |
| :* Then click the Connect button and you'll be set! You can just use this site again if you want to connect to your Wii U. Make sure that it now shows folders on the right side of the program.
| |
| ----
| |
| :* Navigate to <code>storage_mlc/usr/title/</code> on the '''right side''' of the program if you have installed the actual game you're looking for to System Storage/NAND.
| |
| :* Navigate to <code>storage_usb/usr/title/</code> on the '''right side''' of the program if you have installed the actual game you're looking for to an external USB device.
| |
| :* Then, open one of the following folders, depending on what you want to dump.
| |
| ::: The <code>00050000</code> folder stores installed games.
| |
| ::: The <code>0005000E</code> folder stores installed updates.
| |
| ::: The <code>0005000C</code> folder stores installed DLC.
| |
| | |
| :* Once you've opened that folder, you'll have to find the folder that corresponds to what you wish to dump. Inside, find the folder who's 8 digits match the last 8 of the game's title id.
| |
| ::: You can find the game's title ID on http://wiiubrew.org/wiki/Title_database#00050000:_eShop_and_disc_titles
| |
| | |
| :* Before you transfer the files to your computer, navigate on the '''left side''' of the screen to the directory you want to store your games/updates/DLC's.
| |
| ::: It's handy to keep these things separated. Make one folder for the base game (the game without any updates), one for updates and another one for DLC's.
| |
| :* Now, it's as simple as right-clicking the folder you've just found and clicking "Add files to queue".
| |
| ----
| |
| :* Now, repeat the steps from above for each game/update/DLC you want to transfer. Once you're done with adding them to the queue, you can continue with the next steps.
| |
| :* Press CTRL+P to start transferring everything that you've queued...
| |
| ::: This process will take a long while. You can leave the program running while you do other stuff.
| |
| ::: Be really careful to not accidentally delete or mess stuff up! If you follow every instruction carefully, you should be fine.
| |
| | |
| :* You can now exit FTPiiU with the home button and close Filezilla once it's done transfering the files (when it says "Queued files" and nothing else after that on the left-bottom of the program).
| |
| :* Rename each dumped game/update/DLC folder to reflect what it is (like for example <code>MarioKart8_Update</code> etc.).
| |
| :* For updates and DLC's, you'll first need to install them in Cemu first. Read the [[Getting_Started#Starting|update instructions]] for more info.
| |
| | |
| ===Transfering save files between Wii U and Cemu===
| |
| :<code>Make sure that your Wii U is connected to the same network as your computer.</code>
| |
| | |
| :* Insert your SD card into your Wii U.
| |
| :* Open the Homebrew Channel.
| |
| :* For CBHC (Coldboot Haxchi): Run FTPiiU Everywhere.
| |
| :* For Mocha: Run Mocha CFW '''first''' and let the Wii U restart. After that, try launching the Homebrew Channel again, and '''now''' run FTPiiU Everywhere.
| |
| :* On your screen, you should be able to see a line "Listening for data connections at xxx.xxx.xxx.xxx:XXXX". Note down the text at the end with the numbers in it.
| |
| <br/>
| |
| | |
| :* On your computer, open FileZilla.
| |
| :* From the <code>File</code> menu in the menu bar, open the <code>Site Manager</code>.
| |
| :* Click on the <code>New Site</code> button.
| |
| :* Now, you'll want to fill in the Host and Port field.
| |
| :::* In the Host field, put in the longer <code>xxx.xxx.xxx.xxx</code> part you noted down.
| |
| :::* In the Port field, put in the rest of the numbers of that thing you have made a note of, represented by the <code>XXXX</code>.
| |
| :* Go to the "Transfer Settings" tab and click the checkbox to enable the "Limit number of simultaneous connections".
| |
| :* Then click the Connect button and you'll be set! You can just use this site again if you want to connect to your Wii U. Make sure that it now shows folders on the right side of the program.
| |
| | |
| ::: Navigate to <code>storage_mlc/usr/save/00050000/</code> on the '''right side''' of the program if you have installed the game to System Storage/NAND.
| |
| ::: Navigate to <code>storage_usb/usr/save/00050000/</code> on the '''right side''' of the program if you have installed the game to an external USB device.
| |
| :* After you've opened that folder, locate the folder who's 8 digits match the last 8 of your game's title ID.
| |
| ::: Once more, you can find the game's title ID on http://wiiubrew.org/wiki/Title_database.
| |
| :* Open, out of the multiple 8000000X folders that you'll see, the folder that that belongs to your user account. They're numbered in order of creation.
| |
| | |
| :* '''Transfering save files from Wii U to Cemu''':
| |
| :::* Launch the game in Cemu and open your log.txt that's in the same folder as your Cemu.exe file and look for the line where it states your game's "Save Path".
| |
| :::* Go to that location on the '''left side''' of the FileZilla window and open the 80000001 folder. Remove all the files and folders in this folder.
| |
| :::* On the '''left side''' of the window, select all of the files and folders and right-click the selection. Click Download and wait for the files to transfer.
| |
| :::* You can press the home button to quit FTPiiU and test it out. You can also exit FileZilla.
| |
| | |
| :* '''Transfering save files from Cemu to Wii U''':
| |
| :::* Launch the game in Cemu and open your log.txt that's in the same folder as your Cemu.exe file and look for the line where it states your game's "Save Path".
| |
| :::* Go to that location on the '''left side''' of the FileZilla window and open the 80000001 folder.
| |
| :::* On the '''right side''' of the window, remove all of the files and folders.
| |
| :::* On the '''left side''' of the window, select all of the files and folders and right-click them. Click Upload and wait for the files to transfer.
| |
| :::* After it's done, you can press the home button to quit FTPiiU and test it out.
| |
| <br />
| |
| : Extra tip:
| |
| :: If you want to play around with other people's their save files, you can visit these two threads:
| |
| :::* Wii U Save Files Compilation: https://gbatemp.net/threads/wii-u-save-files-compilation.427761/
| |
| :::* Loadiine Save File Sharing Thread: https://gbatemp.net/threads/loadiine-save-file-sharing-thread.414878/
| |
| :: If you rename US save files to EU save files or the other way around, it usually works.
| |
| | |
| ==Starting==
| |
| ===Updating Games and Installing DLCs===
| |
| To add your DLC or update to the non-updated game, it's recommended to install it via Cemu's UI. Once you open Cemu, go to `File -> Install Update or DLC` and go to the update/DLC folder. Open the Meta folder and select the Meta.xml file.
