Hacking [Semi-working] NFS2ISO2NFS - convert nfs to iso and back

[piratesephiroth]

i've already got a vc title downloaded+extracted and I rebuilt it with replaced nfs files. thing is, the iso is 4.7gb so it results in about 16 nfs files, despite the actual game being like 330mb. and it didn't actually boot.

would't code/rvlt.tik and code/rvlt.tmd also need to be replaced? maybe with the relevant files from the original iso?

yeah, you probably need the proper ticket and tmd in the code folder

just taking a quick glance at the two files, they have the original tid of the wii game. so maybe replacing them with files from the iso could make it boot.

so just to be clear. We should be able to inject this via file replacement right? (ftpiiu everywhere) (or... do we need... that program from. THAT site)

Nope, we can't modify nfs files after the game is installed. They seem to require different filesystem commands that are not implemented in IOSUHAX.
They also seem to use a different encryption so we can't do anything using Eyekey's WFS tools either (can't even extract them)

Try injecting exploitable games like Smash or one of those Lego shits, kiddos.

replacing the two files didn't seem to be enough. is packing with all nfs files necessary? I know this game can fit in two.

I'm not sure Brawl would work. It has a lot of partitions, one for each of the VC demo titles. Maybe it works if the game doesn't check their existence.

well crap.... then I guess I cannot do anything. On THAT site, for some reason my login doesn't work what so ever. Yet it works on the sister site (That 3ds site.) (so no program that could make it possible)

So we only have to, download a VC game from JNUSTool (Xenoblade if we want GamePad support), decrypt it, in content folder delete all, put our Wii iso as game.iso, paste NFS2ISO2NFS and open it with Wii common key on bin format and until it generates the NFS files (or one and then split it in exactly parts with HxD) repack with NUS Packer and install? We dont have to do nothing in code folder? Also do we need signature patches to install it? And we have to use original key?
Thanks

Are you sure it's a clean dump? We can't reduce the games' size becaase modifying the partition would require a modification to the tmd, invalidating the signature.

(plus we don't evn know if the game requires any modification in order to work, I know Rhythm Heaven Fever's apploader.img is slightly different in the VC version)

What about injecting it over Xenoblade? That one's double layer too, right?

I suppose you also have to extract the ticket and tmd from the game's DATA partition then copy them to the code folder, as rvlt.tik and rvlt.tmd respectively

Did your tests work with or without them?

I can't test anything right now because my niece is playing on the Wii U.
All I can guarantee is that the iso->nfs conversion works and you get the expected result.

It could be possible that it requires a very special combination of settings, maybe you have to remove the UPDATE partion from the iso or something.
It could also be that the game's apploader and main dol require special modfication in order to work on the VC.
We just don't know.
If it's possible without additional patching, one of us will figure it out and write a tutorial.

I will test with PES 2013, idk which game I will replace, I want Xenoblade for gamePad but maybe that makes problems

and nuspacker doesn't work... fudge

yeah it works, you just need the latest one, from july. (if you repack the original wii vc files, it does work fine)

oh ok (guess mine is out of date)

The gamepad support is implemented in fw.img and it's basically the same for all Wii VC games, only different revisions.
Just enable it in meta.xml and it should work as long as the game supports the classic controller.
