Wii on Wii U Virtual Console: Injecting Games

Requirements:
WiiScrubber v1.40;
nfs2iso2nfs v0.5.4; it may require the Wii common Key. You can use wiiscrubber's key.bin renamed to wii_common_key.bin.
A clean rip of your Wii game;
The extracted contents of a Wii VC title for the Wii U (except the .nfs files);
-the 2 below require java to be installed-
jnustool (requires Wii U common key so you'll have to search online - hint: it begins with D7B0. Open the "config" file in notepad and paste the key inside, replacing [COMMONKEY]);
NUSpacker (must be @ihaveamac's version, requires Wii U common key as well)

Current limitations:
It's possible to use the gamepad to emulate ONLY the Classic Controller.
Wii Remote emulation is possible but there's no gyroscope or infrared commands (at least for now).
(Input emulation patches by @FIX94)

The game must be already compatible with the Classic Controller but that isn't a guarantee that it's going to work.
Here's a compatibility list: http://wiki.gbatemp.net/wiki/WiiU_VC_Wii_inject_compatibility_list

Integrity checks are still in place so only clean disc rips work.
The game iso must be pristine: untrimmed, unscrubbed and the partitions signed.
No homebrew, no mods, no wimmfi patched games until sigpatches are implemented.

Patched isos work now! Original idea by @Tock46!

Homebrew works now, even a special version of Nintendont by @FIX94

Trimmed isos still don't work, at least not isos trimmed by WiiScrubber.



HOW TO DO IT


0. Downloading a Wii VC Title
This may be illegal and I'm just telling you so you don't ever do it by mistake OK?
You can use the command line to download games' contents directly if you know the title id and title key.
I heard you can get them on a certain titlekeys site...

Once you have that, this is the command
Code:
java -jar JNUSTool.jar TITLEID TITLEKEY

Note: You should get a game that contains the latest revision of fw.img (r590), that's the only version supported by @FIX94's patches.
Here's some info you can use to verify that you have a good file:
Size: 1785497 bytes.
CRC32: E2F27E9B
MD5: 3CAF52A9A440EEE4F125A3AD22E305C8
SHA: A5A75EBF3164874830A1D5992495DE510AB3F74E

Now here's a list of some titles that contain the preferred fw.img (verified mostly by @fejich and @markehmus)
DONKEY KONG JUNGLE BEAT [VBXE01]
Kirby's Epic Yarn [VARE01]
Lost in Shadow [VA8E01]
Mario Strikers Charged [VBFE01]
Mario Super Sluggers [VBHE01]
Pandora's Tower [VAPE01]
PIKMIN 2 [VBTE01]
PIKMIN [VBUE01]
Resident Evil 4 Wii Edition [VBDE01]
Resident Evil The Umbrella Chronicles [VBWE01]
Rhythm Heaven Fever [VAKE01]
Sin and Punishment Star Successor [VALE01]
Super Mario Galaxy [VBKJ01]
Super Paper Mario [VBBE01]
The Legend of Zelda Skyward Sword [VANE01]
Trauma Team [VA6E01]
Wario Land Shake It [VBGE01]
WARIO WARE SMOOTH MOVES [VBVE01]





-----------------------------------------------

1. WiiScrubber
First setup WiiScrubber. Remember it needs the Wii common keys so run MakeKeyBin.exe first and do as it says.
Run it and open you iso. Right-click the UPDATE partition and select "Delete partition". Confirm.

Now click on the + box to expand the DATA partition, then expand partition.bin.
Right click tmd.bin, select "Extract" and save it.
Do the same with ticket.bin.

Rename the extracted ticket.bin to rvlt.tik
Rename the extracted tmd.bin to rvlt.tmd

Copy/move both files to the "code" folder of the Wii VC title.

Your iso is now ready and you can close WiiScrubber.


2. nfs2iso2nfs
Move your iso to the "content" folder of the Wii VC. Rename the file to "game.iso".
The content folder should contain only game.iso and the "assets" folder. Delete any nfs files that are still present.

Copy nfs2iso2nfs.exe to the content folder and run it. If everything is in place, it will begin the conversion process.
It should take around 15 minutes. Its console window will close when it's finished.
Once it ends you can delete your iso file and nfs2iso2nfs.exe (and wii_common_key.bin if it exists).
The content folder should contain only the nfs files and the "assets" folder.

Optional: You can enable Classic Controller emulation for playing using only the gamepad.
Open meta.xml (it's in the meta folder) in notepad.
Look for the line
Code:
<drc_use type="unsignedInt" length="4">1</drc_use>

replace it with
Code:
<drc_use type="unsignedInt" length="4">65537</drc_use>
and save the file.
Note that this will only work if the game supports the Classic Controller.
If it doesn't either it won't boot or you won't be able to do anything and only the gamepad's power button will work.
Here's a list of such games: https://wiki.gbatemp.net/wiki/List_of_Wii_games_compatible_with_Classic_Controller


3.NUSpacker
The final part, building the installation files.
NUSpacker requires the Wii U common key. You should find it online and then open the file "encryptKeyWith" with
notepad and paste the key inside (hint: it begins with D7B0)

It's also a command line tool so you'll have to write down the commands, or simply create a new text file,
write the command inside, save it and change the extension from .txt to .bat

I recommend copying the Wii VC folder (that contains the other 3 folders, code, content and meta) to nuspacker's folder.
That will make everything easier.

The command works like this (replace with the names of your own folders)
If you folders have spaces in their names, enclose them in quotation marks, like "Just Dance".
Code:
java -jar nuspacker.jar -in GAME_FOLDER -out INSTALATION_FILES_FOLDER

Wiait until it finishes the process.
Now just copy the folder with the installation data to the "install" folder SD card, run a CFW and install it with WUP Installer GX2!

PS: If you make a nonfunctional game, remember to uninstall it before trying again.
If you install a fiunctional game over a broken installation, it will still appear as broken.

Do you manage to boot WiiXplorer from the Wii VC? :P, does the gamepad work?
Yes I managed to make a homebrew VC but sadly gamepad doesnt work in any hombrew.. The way the hombrew devs use classic controller and nintendo use classic controller are completely different so its not recognised.

--------------------- MERGED ---------------------------

the fact that everything is said to be disabled even with ios249 is a pretty good indicator that it never actually reloads IOS and just changes the reported numbers, if you do the same test on regular wii mode it will probably look much different.
Yea it does.. Do you think it would be possible to somehow merge the fw.img ios into an existing vwii ios?

do you know the mapping for all the buttons? For Rhythm Heaven, for example, it would be probably better to remap B to ZR

I just noticed that the "sideways wii remote" patching isn't necessary, at least for the fw.img packed with Rhythm Heaven Fever.
The d-pad already functions as expected if we enable Wii Remote emulation.
Applying that patch will only rotate the d-pad counterclockwise, simulating a VERTICALLY held Wii Remote.
that is becuase rithm heaven is not a sideways wiimote game lol its a front wiimote game.

Can anyone help me? when i get to the NUSPacker part, it gives me an error
Generating the FST.
The file "fw.img" is not assigned to any content (.app).
Please delete it or write a corresponding content rule

When you choose not to use gamepad emulation, can you use multiple wiimotes?
Nope, it seems that only the gamepad's emulated commands are acepted when controller emulation is enabled.
Any other wii remote is ignored.

EDIT:, oh, you mean when you chose NOT TO emulate.
Yeah, of course it works normally and accepts any number of wii remotes.

So, today @pedro702 did a couple more tests for me and we got the gamepad data read out using the same fw.img as I already used the other day (the crc32 e2f27e9b one).

First you need this simple patch:
offset 0x1478A from 0x6818 to 0x2000
Set drc_use to that value needed for the gamepad classic controller emu to work, you can still use homebrew as you normally would in vwii mode, using a real wiimote with that patch.

Then there is this patch that moves down the gamepad data area low enough so wii apps can actually read it out with memprot and ahbprot still enabled:
offset 0x119A0 from 0x138BA004 to 0x13210000

And lastly, just to give a quick thing using the gamepad in wii homebrew I threw this demo together.

It just prints out all the buttons/sticks on screen, source is included.

While it is not much at least it shows that yes, you CAN use the gamepad outside those official wii games.

@piratesephiroth

What did nfs2iso2nfs 0.5 update? Does your project have Github links?
I changed the patching code to make it faster and also added the new controller emulation patches.

Here's a new version with the new experimental patches from @FIX94
EDIT: fixed wiimote patching description.
The additional patch is necessary for vertical wii remote emulation, not horizontal.

View attachment 98564

I didn't submit a pull request to the original repository yet because the patches are kinda experimental and it seems there can still be more coming, like the one for homebrew apps above.
