[EmulateLife]

this is an amazing tool, i just wish i could get it to work.

could someone give me a few simple steps how to merge an nsp update file into an xci and save it as xci ?

im trying but i keep getting an error stating failed to execute script squirrel



this is literally the game i want the nsp to merge with its xci XD



im getting the same thing

If you had just read the last page you'd have your answer. I even gave the answer to the person you quoted you need 7.0 keys use Lockpick_rcm google it and follow the instructions.

i have MK11 with the update 1.0.2 in one singel XCI file
i see it in SXOS but when i start the game it`s say gamecard could read?

There exists a bad 1.0.2 update (without tickets). Try another one.
Building a working XCI with NSCB for MK11 +UPD 1.0.2 +DLCs works fine with 7.0.1+SXOS 2.6.2

I had MK11 and 1.01 update, and it was about 20GB. As soon as I create an XCI with the 1.02 update, the resulting XCI is 41GB. Will this not cause an error saying "game card could not be read", as that would mean a 64Gb card, which aren't in use officially yet?

These are the instructions for the Lockpick_rcm.. I missed to the first time cuz Google took me to the Download..

• Upon completion, keys will be saved to /switch/prod.keys on SD

If the console has Firmware 7.x, the /sept/ folder from Atmosphère or Kosmos release zip containing both sept-primary.bin and sept-secondary.enc must be present on SD

There's no reason to combine two updates you should start over with MK11 xci or nsp which is like 7 gb and combine it with 1.02 which is like 16. I have no idea if it'll even work but it's a waste of space. You're doing something abnormal so it wouldn't be surprising if it made the game too big to work.

Only thing I could think of is (haven't tried) is when you get to the option to remove (1) update, (2) dlc or (3) update and dlc. He must have accidentally chosen option (2) leaving the previous update?

has this been updated to allow games to be run with 7.0 keys? the highest I can go is 6.2 so far, even though I have keys from 7.0

It does work with 7 keys. Did you use lockpick or lockpick_rcm? Only lockpick_rcm will give you 7 keys.

I tried the Combine multiple files into 1 XCI which works fine under SXOS, and also installs fine if I decide to do that.
Now I tried the Multi content splitter to see if I can delete the different NSP's since they are included in the XCI but the resulting NSP files are about 5kb smaller than the original files.

Is there a reason for that? I am not at home to test and see if those work.
Checking with Switch Backup Manager 1.1.9 it seems it is missing all of the meta data and picture. So it's not completely rebuilding it with the required information.

Edit:
I get while running Spliter mode for every file:
-----------------
Repacking as nsp
-----------------
Generating nsp:
- Writing header...
- Appending e..d.nca
- Appending f..4.nca
- Appending 9..5.nca
- Appending 7..8.cnmt.nca
Too many arguments in command line.

It does however create(s) .nsp file(s).

Getting this error when trying to process a custom XCI (Mortal Kombat 11):

Exception: local variable 'docheck' referenced before assignment

It may well be the same error I got a few pages back on Sports Party

I already got my 7.0 keys, but NSC builder only allows me to downgrade the compiled games to 6.2 as the highest firmware. I know I can just leave them alone, but the reason I ask this is because 8.0 is now out. If there is a game that requires 8.0 but can be downgraded to like 7.0 I would prefer that.

 

[JRoad]

I'll try to correct the last reported issues and if I have time unify the beta and the stable in one during the weekend. Between the holidays and a busy return to work didn't have time these last weeks.

 

[brollikk]

were there even 7.0 specific keys? like is it even possible to make an 8.0 only game run on 7.0 now? or is that not a thing

I’m having a strange issue using the update mode to build a custom xci...everything looks like it should until it starts generating the xci. It begins “appending nca” but the file always ends up being 2-3 times bigger than it should be. It never gets to 100% but gives me a massive file in NSCB_output. I’m in the process of trying again with 8.2 and default settings but I’m already seeing 40GB I’ll edit my comment and post the error when it comes back up.

@Alchemy_Gaming
I think i have that error corrected among others for the next version. It'll should be up trough the following days, though the multimode from the beta updates files so you can use that.
@markmcrobie
That error is normal, it means it means when decrypting the nca header the result is not correct, basically it can't see NCA3 or NCA2 in the header which are the header magics used till date so either the magic changed to NCA4 or the header is messed up. The nca header should use the header key so if it's working for other files the key should be fine.
Either way something weird is happening there since the titleid that it's being detected for the xci is the update one, so that means it's not detecting the base game there in either of those files.
Edit: The update magic for minecraft is NCA3 and it's read fine so i bet the issue is with the base.

Thanks! I'll wait patiently I tried the multi-mode and got an invalid argument/failed to execute squirrel error. My xci conversions are still working fine just having issues building with updates. I'll live with that until I can try the new release. Thanks again for all your hard work!
