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

[CatmanFan]

Have we tried brute forcing the EGGS-SGGE header if it's the same for every game, or is it not the same?

Probably won't work.

Probably won't work.

Well, if it's our easiest option, why not try it?

 

[Naendow]

You can't talk about the easiest way. Brute forcing needs time and luck.

Yes but with some organization we could reduce time and improve luck

For example, try to md5(n) first bytes, we could split n in range to distribute work to several people.

Same with md5(base64(, etc ...

It seems to need the header for decrypting or something else, you can't just "brute force" it, needs to be reverse engineered.

Note:
This does not mean that Wii VC injection is working! There is still an 8 byte part of the EGGS header, which is unknown. This program fills this part just with zeros. However, @JaGoTu10 hasn't found any code in the WiiVC's fw.img that checks those 8 bytes, so setting them all zero *might* work.

I was just reading this, does this actually work for some injected Wii ISOs?

dunno if anyone has figured this out already, but here's my modified NUSPacker that properly sets the entry type for Wii games (specifically, files ending in "nfs"). I tested this with an existing Wii VC title and the repacked title worked after installing. I did not seem to get a custom game working though but I probably just did it wrong.

https://github.com/ihaveamac/nuspacker/commit/797b84af32e5bb0c353577a7a3f67e236f7b7ee3
binary: NUSPacker.jar

it sets the file type for the nfs files to 0x02, as you can see here (file-list below): https://gist.github.com/ihaveamac/86aa17d368adc9c79ee8594d5923ae80
directories are 0x01, files are 0x00, deleted entries are 0x80 (probably for updates that remove files). but notice how the nfs files are 0x02. that was all that was needed to get a repacked existing game running.

The problem with custom games is that they aren't working. We still haven't reverse engineered the EGGS header of the NFS files properly therefore we cannot run these NFS files converted with this program yet.

I know custom games aren't working, but I know the other issue was trying to properly pack the titles so they ran at all (including games already in "EGGS" format).

I noticed someone was using an SDK tool to do that, so I guess this would be a "legit" method to do that now.

Wow, so all that's left is to figure out the header?

Seems like it to me!

 

[bennyman123abc]

Of course, no one here has the ability or has at least tried to decrypt the header. I know I don't know how.

well I figured posting this would help those trying to figure out the header, since they'd be able to test their changes on console. ¯\_(ツ)_/¯

yes! this is something we need! I hope we figure out how to do injects as well.

I tried repacking Xenoblade and it didn't work. All I got was a blackscreen.

How come you got bluescreen?

did you repack the existing version from eshop, or a custom-made nfs? the latter still doesn't work afaik.

just extracted and repacked the eshop version without modifications.

I got a redscreen :^)
