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

[sabykos]

Wow it seems like you guys are really close. I originally stopped working on this, because I never figured out how to pack my files into an installable format. If I see tht correctly the only thing that might be a problem are the 8 bytes in the header. As far as we know fw.img never checks those, but I'm still sceptical.

I am getting an aneurysm... I already said 3 times that the 8 bytes in the Header does not matter at all Original Wii VC install fine when you change it to 16*0xFF for example.

Haha, sorry missed that. Well then I guess it is done once piratesephiroth reversed the process.

 

[piratesephiroth]

it's almost done. I just have to finish iso to nfs conversion.

hmm... it seems it's done.
Converted dumped legitimate iso into nfs files that are identical to the original ones (except for the zero padding at the end of the final file, I didn't mess with that part of @sabykos code and it doesn't seem required anyway).

I'll just make a final test with Resident Evil IV Wii Edition because it's one of the largest wii virtual console games if not the largest (4GB)

that theoretically could be a problem. There could be a possible read limit. (however i have very little knowledge so take what I just said with a grain of salt)
Also HYPE

Xenoblade is one of the largest and one of 11 which were released on Dual Layer discs.

Pretty sure Nintendo padded the last 32 kb chunk instead of cutting it off at 18 kb for example.

Xenoblade was released as WiiU VC though.

yes i guess thats true .. haha forgot i bought that for the controllers it allows

There

Now you can convert anything. Let the injected Wii VC tests begin.

Just tested a fake signed (modified) ISO and sadly those don't work. Will test with a cleanrip rip next.

so homebrew isos are a no go then? was thinking of making a nintendont iso so I can load GC games.

yeah, I suppose fw.img can be patched to bypass the signature check

 

[sabykos]

So for now only cleanrip dumps?

yeah, all we can guarantee is filesystem integrity.
(btw I made the pull request)

so assuming I had an iso dumped using cleanrip (ac:cf usa), what would I do to "convert" this to nfs properly? I know how to pack into an installable format already, but I don't know how to convert to working nfs.

get a Wii VC title (it's best to download everything but the NFS files using jnustool) then just copy the iso to the content folder and rename it to game.iso.
Then copy nfs2iso2nfs to the content folder as well and double click it.
(you'd need also the wii common key in a "wii_common_key.bin" file but I already included it in my compiled exe)

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?
