Hi there!
Russian-speaking community presents a small bat-script to check the integrity of NSP and XCI, and generates MD5.
The instruction is in the readme file.

Do not pay attention to WARNs

Is GOOD is not enought for you? I can change it for AWESOME

Good is fantastic for me was just asking in case i had dome something wrong.

Based off "Switch Game Checker" this bat checks signatures of all NCA files in game.

Tests XCI, NSP, and NCA files. Drag game onto "verify_GAME.bat".

So I tried this one again and it does work, it just takes a long time on a blank cmd window. The thing is, it only shows the MD5 when it finishes, not telling me if it's safe or not. I've tested several games and all show the name of the file and the MD5 in a green color.

Green color is for good. But idk why it is not shown any info for you. Vary strange

I used his, not yours. Yours still doesn't work, it only shows the cmd for a split second. But I'm going to assume his uses the same color representation for validity as yours does.

Could anyone explain to me how to use this software for noobs? i dont understand what i supose to do with this, and i want to keep safe my console

In a hypothesis if i use malicious xci it just break my emunand or whole console?

The readme file has clear steps to use the script, there are few of them.
About brick. If we talk about brickachu (tinybrick), it will break cal0 emunand without affecting sysnsnd.

OMG My copy of super smash bros is poisoned md5 says "its bad" , what should i do? that´s a kind of big brick/time bomb or something? i want to know all types of bricks! pls help

Converted xci < > nsp show corruption. It doesn't mean that brick is there, it means that the signature and integrity are broken. Such backups are better to use only from reputable sources.

Script was updated.

Seems to be working great for me, thanks very much

I've found that if a xci is decently converted to nsp, it will pass the md5 test.

how do i run this on mac (terminal)?

You should use check_nsp.sh (bash).

Got it. Works great. TY

I've downloaded a converted xci to nsp of Civ VI and it passes the test.

How you know that was relly convert? Convert by yourself and test it

It was a leak of the cart, therefore it was impossible to be an nsp in the first place. Same thing for Let's Go Pikachu and Smash.
I don't know if it's because I'm using verify_GAME.bat instead of check_nsp.bat, since that one never worked for me.

 

[SaffronXL]

I have the same issue as Sharinflan, verify_GAME.bat posted here works great, while check_nsp.bat from the github just immediately closes.
Nevermind, I'm an idiot. Make sure to copy the CONTENT of the batch file on github.

The only issue I'm having now is both the temp folder and check.log aren't being deleted automatically.
