Hacking Discussion PSA: SX OS's NSP installer can corrupt the installed game

[hippy dave]

Conclusion: use BBB nsps
I’ve tried BBB NSPs and they are not corrupt.

It's the installer not the NSPs that are the problem.

It's the installer not the NSPs that are the problem.

Then explain to me why it get corrupt with normal nsps and not with bbb nsps?
Are you implying I’m lying ?

Ok that's a new one on me, tho I didn't think it corrupted every time anyway, so it's interesting if this is actually a factor and not just random chance.

 

[NeoSlyde]

Also even tho it shows corrupt they works perfectly fine.
I think it’s just some md5 mismatch or smtg minor like this.
No need to worry.

You seem confused.

Have not had any issues with this, must note I only did a few NSPs as of now.
Testing 7 later on. If I run into any issues I will report but if it was SX OS's installer ... aka basically tinfoil.... then we would have heared more about that I am guessing

It's not just a SX OS problem i installed five games with tinfoil. Three show as corrupt and two fine. I have completed all three of the corrupt games with zero problems.

BBB mentioned in the dumps the cdnsp downloads were not correct that’s because they are missing some files that are not important/necessary to the install so when the switch does a corruption check it finds the missing files are not there so it flags up as a corruption but the game/install itself is fine and should work perfect. Maybe your flashback error might of been a one off or something I wouldn’t worry.

I'm pretty sure it's been shown that the extra files BBB put in their NSPs are not actually installed to the Switch, so that can't be a factor.

My Zelda title was corrupted some days ago, maybe it's this.

Wait what happens if i redownload the game after finding out it's corrupted?
I installed couple nsp games using tinfoil and every single one is corrupted. I decided to redownload them. Now my switch is occasionally freezing and gives 2144 0001 error code while playing. I wonder if this is the cause?

Yep, just what I figured earlier, just a MD5 mismatch.

2144 0001 error can also happen with xci games and even just playing homebrew so I doubt it's caused by a broken nsp game.

The "corruption" is probably merely some misaligned encryption or hash check that the firmware doesn't understand.

I have 30+ nsp's installed on my switch -all using sx os-, and I've fully -completed- several of those games.

Zero adverse effect whatsoever, and no games have had any issues at all. Just because the system "thinks" something is wrong doesnt mean there is. We are doing things that the system never intended to happen or much less have an understanding of using tools that arent written by nintendo, things can happen in these scenarios.

 

[Kupie]

The 20+ games I've installed and played must be corrupt, then!

To be sure it is best to verify the NSPs were not corrupt to begin with (or you get a false positive). We know CDNSP/Dodge have packed corrupted NSPs. Not saying this is the issue just be sure to run the verify tool on NSPs before installing. idk maybe corrupt NSPs can't be installed anyway? I never tried to install a corrupt one.

EDIT: Oh sounds like it is an SX OS bug: https://team-xecuter.com/forums/threads/154708-SxOS-installer-bug-located

Confirmed, Game_Over.

Do you even read?

And your point is what?

 

[ValenValentine]

So far I tested for corruption. It is in fact present with SX OS installs, so thank you for pointing this out.

We need more data before people say things like "but it works fine" and this "shouldn't be a PSA". I'll update any games that don't work due to corruption...that said, so far it does seem an md5 mismatch or something unimportant...SO FAR. Please post if it effects your game, and in what way. I may have to start using dev menu if it starts sounding bad out there :/

I agree there is a slight bug in tx’s installer but nothing that is effecting the title from working properly, the TX installer is picking up a mismatch that the Devmenu installer isn’t but nothing worth worrying about to the end user. If your picky and want a clean checked “corruption” free install then use the devmenu, if your not concerned keep using the TX installer it won’t hurt. Gaming bugs could be just down to having corruption in grabbing the nsp off cdnsp, if it’s not a clean download from cdn to install it can have issues.
