Well, time for another update!

After experimenting with the IPAKs, I managed to put some custom textures in, I only tried this for Zombies (the Nuketown one) but it should be possible to do some custom camos and stuff with this, I'll try to do something with it and try to post it here soon.

For now, here's the custom texture I imported as a test: (image here)

On the other part, I can confindently announce that we formed a team, 5 members with dedicated roles, this has truly improved our development process.

I'm currently working on with the shaders of the PC version of zm_nuked, don't expect seeing gameplay too soon but I'll try to keep you guys informed since yall really like this project : )

Expect another YouTube video about this on my youtube channel soon.

Until the next post.

^(i need ideas for the name of the team)

hey there guys, after the progress made in the previous parts, the BO2 Wii U DLC restoration project has reached another important milestone.

^(funfact: it was done yesterday after i made the post but didn't had time to post it yesterday)

The biggest update: the DLC IPAK is now fully loading!

After working more on the files from the title screen, I managed to get the DLCZM0_LOAD_ZM.IPAK to load correctly, allowing the game to recognize and process more of the missing DLC assets. This is a big step forward compared to the previous state, where the IPAK could only load the map icon: Now it can load the loadscreen and the two background versions.

State of the Project:

1. DLC audio files successfully ported
2. DLC IPAK now fully loads
3. DLC textures can be extracted and converted

However, this is where we need help.

The next major step is getting the actual map assets and the fastfiles working. We need more people with knowledge about:

• Black Ops II / Engine formats
• Fastfiles (.ff) MOST IMPORTANT
• Map assets and zone files
• Wii U reverse engineering (to work with shaders mainly)

The goal, for anyone who missed the last posts, is to restore the cancelled Wii U DLC and make it playable, starting with Nuketown Zombies, and eventually Die Rise and the DLC1 MP maps.

If you have experience with Call of Duty modding, reverse engineering, or Wii U development, any help would be appreciated.

Even small pieces of information about BO2's internal formats can help move this project forward.

thank you everyone for your support and kind words, you're really the reason I don't give up considering how hard is this : )

Well, now the IPAK loads a bit better.

Yesterday, I reported that I was going to work on the IPAKs, the texture files where BO2 stores... it's textures (duh), well, now I got one partially to work.

I managed to extract the PC textures of dlczm0_load_zm.ipak, where the map selector + backgrounds + loading screen of Nuketown Zombies are stored, I tried to do a faithful conversion.

Well, the map selector image works, not the background or the loading screen (Well, I don't reach the loading screen due to the zm_nuked.ff file being missing, but I guess it won't load anyway.)

I'll try to work more onto this, I need to look for more members to work into this so we can form a team (we're currently just two guys doing this) to speed up development process, so if anyone knows about the Black Ops 2 formats for PC or Console and are interested into this project, any kind of help is welcome 😄

tl;dr: found the loader file and managed to port out the missing audio files from Nuketown Zombies to Wii U, now the map at least tries to load, VIDEO BELOW.

In case you didn't saw my last post, I'm doing a research + reverse engineering over Black Ops 2's Wii U version scrapped DLC; long story short, DLC was planned and almost everything was already set up minus the actual map files.

After messing around downloading old updates for BO2, I noticed that in the TU's v16, v32 and v48 there was this file

dlczm0_load_zm.ff

holy fu-

I was looking to recreate this file for a while, it's supposed to be the loader for the DLCZM0 (Nuketown Zombies if you aren't aware), I tried when I first started this project back in February to recreate it but my attempts were awfully bad since I didn't had much experience.

After loading it, thinking it would produce a change into my BO2 (That is patched so the game actually displays both the two Nuketown and Die Rise maps as "available" to spoof the license check), it just crashed. After checking the Cemu logs, it said that zmb_nuked_real_intro.all.sabs was missing.

After spending a day figuring it out, I managed to port (in mono audio tho) the audio .FLAC file to the DSP audio format that Wii U uses and recreate the .sabs container file, the results for this now functional file are in the attached video.

What does it all mean? Well, now that we know that the rest of the audio banks are in the disc of the game, the audio part is ready, I need to tackle now the Fastfile and IPAKs portion of the porting process.

Wish me luck cause this is the hardest part, but at the same time I'm motivated to keep going until the map is finally playable on our Wii U's xD

BTW: Textures for the map selector aren't working just yet because of the missing dlczm0_load_zm.ipak
