I want to share something that I've been working on for a while
It started of as an experiment to add LibHac to Switch Backup Manager, but as it was easier to make a new project instead of doing with an existing app with already lots of things in it, it progressed as a separate project. Although because now it is a separate project, a macOS build was made possible


NX Game Info

Tool to read information from Nintendo Switch game files, with the following features

• Read NSP, XCI and installed titles from SD card
• Game files structure (Scene release, CDN rip, converted)
• NCA signature (Verify if it's official Nintendo titles. Unmodified titles should pass this test)
  
• FS permission (Read filesystem permission. Game titles should not have excessive filesystem permissions such as EraseMmc)
  
• macOS and Windows build

To use this app, you need to provide 4 files

• prod.keys: Your usual keys file, also commonly found as keys.txt in other apps. Can be obtained from your Switch using Lockpick
• console.keys: SD seed key, can also be obtained using Lockpick. Please refer to this for more details. This is only required for Open SD Card to function, and only sd_seed key (along with sd_card_kek_source and sd_card_nca_key_source in prod.keys) is required. Other keys can be ignored
• title.keys: Title keys file, support any popular format such as from newkeydb or nutdb. This is required to read FS permission for games using Titlekey Crypto. Also used to map game title name and latest version if available. For more details see https://github.com/garoxas/LibHac/blob/NX_Game_Info/KEYS.md#title-keys
• hac_versionlist.json: Version list file, can be downloaded from https://pastebin.com/raw/9N26Bx10 (updated daily). No DLC version

For more details, please refer to https://github.com/garoxas/NX_Game_Info#how-to

Thanks to

• @minibar for LibHac
• @GibaBR for the inspiration with Switch Backup Manager
• http://switchbrew.org/

For macOS Users

If the app suddenly closes when you try to run it, go to System Preferences then to Security & Privacy, there you'll need to select Open Anyway to be able to run this app

Looks like that one is working with the dump I already had for testing.
I'll dump a few fresh ones and test with that, and I will let you know!

Thanks for your effort so far!

great

@Garou

It doesn't makes sense! Look at this:

Help ?

you need to put prod.keys file in /Users/yourname/.switch directory on Mac

 

[spotanjo3]

great

you need to put prod.keys file in /Users/yourname/.switch directory on Mac

It works! Why can't I just put NX Game in NX Game folder along with prod.keys file in it ? It won't work but put them in /Users/yourname like Download directory on macOS and it works.

iirc because the app is sandboxed, so "current" directory will be different than what you expected to be
the general approach was to put supporting files somewhere else. the most common way was to put it in /Users/yourname/Library/Application Support/applicationname but I felt that using /Users/yourname/.switch is more straightforward (and this approach also being used in other app such as hactool)

I understand. Maybe you can do that for directory ? I like to make a folder for it and put them inside it at Downloads directory.

I tried to scan all of them in NSP include dlc files and works okay. And I scan all of them in .XCI files and it crashes.

the path needs to be predefined in the app, so basically I need to choose 1 specific path that works for everyone. custom path is not possible, sorry

are they proper XCI dumps or converted from NSP?
if they are proper XCI dumps, let me know the game name so I can check

 

[godreborn]

converted xci work in windows. I dunno about mac.

They are all properly XCI.. No converted at all.

I open Directory in NX and scan XCI files on my external hard drive where all XCI files stored. They crashes immediately.

I open Directory to where clean NSP files (no converted from XCI either) stores in other folder in external hard drive and scanned and verify all passed.

can you try open just 1 xci file and see if it crashes? I'm guessing maybe there's a corrupted xci in the directory and the app crashes when opening that one
also please send me your debug.log

converted xci work in windows. I dunno about mac.

thanks for the info

 

[godreborn]

I'm not sure how to determine if an xci is corrupted, but I do know how to with an nsp. however, the app, nsp verify, throws a false positive for nsp games or updates that have been modified to work on lower firmware. I have all of my unverified nsp files in a separate folder atm.

One xci file works and no crashes. All of them at once crashes.

I think I know why.

Title.keys
Console.keys (What's that?)

Are they the reason I need ?

I think not.. Correct me if I am wrong. It doesn't matter because if one XCI file works fine then why not all of them ?

converted xci work in windows. I dunno about mac.

Yes, converted xci work in macOS. I did before.

 

[godreborn]

you can tell what's converted with switch backup manager. it will say that the origin is xci. that's in case you downloaded the files. I have my converted files in a separate folder. I don't know much about exploiting the switch, just enough to get all of my bought games downloaded and checked.

you don't need to worry about console.keys for now. that's for Open SD Card option, see https://github.com/garoxas/LibHac/blob/NX_Game_Info/KEYS.md#console-unique-keys if you're interested

I think not.. Correct me if I am wrong. It doesn't matter because if one XCI file works fine then why not all of them ?

as I said before, if there's 1 corrupted xci in that directory and the app doesn't know to handle that, it may throw an error causing the app to crash
unless you're willing to test all xci files that you have one by one and see which one causing the issue, unfortunately there's no way for me to narrow down the issue. sorry

wait what? you'll only get that error message if your prod.keys is empty (or no correct keys in it)

Thank you. I deleted console.keys anyway. I go ahead and highlight them all by Open file at once. Everything is good. Thanks.

works fine for me, but I'm on windows.

Something is wrong. Now it is not working. I used old version and it works but the latest version aren't.

I have NX Game Info (the latest version) and prod.keys (The latest version) in the same directory. And I got the message:

try put prod.keys in /Users/yourname/.switch and see how it goes. and when you said latest version, does that mean the one from release page (released almost a year ago) or did you build from source?

A stable release version of 0.7.1. You are right. It works now. Sorry to pull you in for the trouble.

And I have an idea.. Maybe you can drag and drop on it instead of going to file to find it ? It would be easier. What do you think ?

that would be neat idea, thanks. I'll consider it whenever I find the mood to update the app
