Hacking Manually updating romfs.bin for backups

[Zumoly]

hmm i dont quite follow... are you able to provide steps?

I'm able to extract the DLC .nca file into a folder, but how do i merge with the game?

Actually you extract the romfs folder for the base game and the update first as a folder, then you extract the dlc which is section0 cause as you said there will be mismatch if you attemp them together. See these commands for instance:
1. Merge base & update as folder: hactool.exe -k keys.dat --titlekey= --basenca=Splatoon2stock.nca --section1dir=romfs --exefsdir=exefs Splatoon2Update.nca
2. You'll get an exefs folder and a romfs folder. Then you use this command for the dlc: hactool.exe -k keys.dat --titlekey= --section0dir=romfs --exefsdir=exefs Splatoon2dlc.nca

So , all dlc are section0 ?

Yep!

 

[huma_dawii]

Yep!

but then you end up with a romFS folder which for LayeredFS wont work. We need RomFS.BIN

Layeredfs works just fine either with romfs.bin or romfs folder. Look at the hbmenu folder! I even tried with kirby to confirm this.

 

[huma_dawii]

I see that case with DevMenu over Pokémon Quest...

Before I tried with just the folder and it didn't work :v


EDIT:

Extracted everything (imcluding DLC) and im gonna test now, lets see if it boots :v

And I was right, if its not romfs.bin XC2 wont even boot.

Region matters for updates and dlc. Try extracting only the base game as romfs folder and see if it works. I update kirby this way as it's only a matter of merging folders.

I'll try tonight updated v1.5 Zelda with dlc as it's region free
never tried romfs as folder. I'll let you know if it works.

I'll try as just folder and report back. (just the base for now).


EDIT: So many little files T.T its taking forever.

Well I'd say it's a one time process if you get everything right: Game+latest update+DLC

DLC works regardless of the legitimacy of it? Because I doubt it xD

EDIT:

Game loads over Octopath Traveler V5 of SD Files, just the base for now... I will add the Update and DLC next.

EDIT: After I injected the save file from my XC2 the game just crashes!

i did a quick test using Splatoon 2 (base only) since its small in size but didn't work

//atmosphere/titles/<donor id>/romfs/<extracted files>
//atmosphere/titles/<donor id>/exefs/<extracted files>

then i tried
//atmosphere/titles/<donor id>/<romfs extracted files>
//atmosphere/titles/<donor id>/exefs/<extracted files>

crashes upon starting... but since you mentioned Xeno 2 base works as extracted files... ill have to test that out later today

Me too I'm gonna test more, my XC2 crashes after injecting my save ad it won't boot anymore even deleted the save with no luck.

I'm going to test latest update as romfs.bin, the same as romfs folder, then game+update+voice pack as romfs folder and let you know the results. Everything with SDFiles v5, Horizon 5.1 and with SMO as Donor. But it's soooo long to transfer everytime (i'm using memloader moreover)

Don't use memloader to transfer big files, use an sd card adapter instead.

I don't have an SD port on my computer nor SD-USB adapter

Any idea of why the game crashes after first boot being fine?


EDIT: besides the obvious, injected save....

I'm not sure but when the romfs is extracted as folder a new save is created for it! So I'm guessing it's rejecting older saves from older game versions. W2 tells you that trying to resume your progress of the level will reset you at the start of that level cause it's save from an older version of the game.

SD-USB adapter

Trust me: get one and your transfers will be much quicker!

That was my idea too, it was before I updated the software, so my save is Obviously from the most recent update plus the dlc so maybe that is why, gonna have to reset all what I did to test one more time, this time with update included

 

[HoTsHoTz79]

@huma_dawii im counting on your testing! i got all my extracted files ready and .npdm patched for octo... (going to test 3 seperate scenarios: base first, then base+update, then base+update+voice pack dlc) but couldn't transfer to test as i had to leave for work
also, can you confirm if this is how you got the base game running? (2 folders, romfs and exefs within donor title)
//atmosphere/titles/<donor id>/romfs/<extracted files>
//atmosphere/titles/<donor id>/exefs/<extracted files>
