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.

I think so (?
Afaik @piratesephiroth confirmed this.
yeah it seems to work well.

I'll see how many versions of fw.img are there and list on the tutorial so people can test their game compatibility.

EDIT: It seems all games use the exact same fw.img only each one has some weird encryption in some parts that I didn't figure out.

Just tried this with Fire Emblem: Radiant Dawn using Rhythm Heaven Fever, and the .app files are too big to fit on a FAT32 SD card... Did I do something wrong, or is there some way to get these to install?

So, can we launch homebrew via in-game exploits like IndianaPWNs or other exploits with gamepad control?

I will probably give this a try since save exploits do not require editing the iso and thus should work with no sigcheck patches.

@piratesephiroth great guide but your contradicting yourself at the beginning a little, your saying this> Requirements: The extracted contents of a Wii VC title for the Wii U (except the .nfs files); then your saying this> 2. nfs2iso2nfs: The content folder should contain only the nfs files and the "assets" folder.

Which is it? are you saying you should delete the original .nfs files from the wiiu extraction before you convert with nfs2iso2nfs and then the new conversion from nfs2iso2nfs creates newer .nfs files for nuspacker?

Syscheck displays something on the screen then reboots the wii (I'll have to see if i can grab what it says before) and dopmii just shows the name of the app in a red banner on the top of the screen and freezes..
Interesting, so they do boot, but I assume what happens is an issue with trucha or missing cIOS, as stated before.
It'd be nice to see what comes from this.
BTW how big is the fw.img?

the folder should contain only nfs files AFTER you're done converting the iso.
I think I should specify that there should be no nfs files BEFORE the conversion.

Ok so.. I managed to get a shot of syscheck before it reboots, I'll write what it says:

Code:
Region: unknown
The System Menu v610 is running under IOS255 (rev 65535)
Hollywood v0x0
Console ID: (my console id)
BootZ v0

Getting number of titles..... Found 88 titles.
Getting list of titles...

Found 32 IOS and 0 IOS Stubs on this console.

Initialising the FAT file System....
Unable to initialise the FAT file System!

Thats exactly what it says (except the ConsoleID part of course)

My fw.bin is 1.70mb and is from the DKCR VC

Oh dang. Ios 255 is rather interesting.

Either Systemcheck gets it wrong, or Wii VCs use it.
