Read https://github.com/switchbrew/libnx/issues/161

Already read it. Even though it's a problem in Nintendo's OS.. the corruption only happens when using HomeBrew which is accessing the FS.

If corruption was such a major issue for Nintendo, I am fairly certain it'd have been fixed by now as QA would have flagged it.
It's obvious they don't see a problem with it after at least 8 system updates.

There is a comment in there that explains why it's an issue in Homebrew right now. Let me link the specific comment(s) that explain it.

In order I suppose:

As you have read there, this issue is most likely due to fsdevCommitDevice() function issue where sdcard data is not completely saved with homebrew in some cases (from my basic understanding of programming anyway) This works fine in OFW because In OFW it only ever touches SaveData. CFW does more. I don't believe Nintendo will ever fix this because it will never affect them. And they have been known to not be compliant with the homebrew community.

Weird.. If ExFat works just fine with Nintendo's OFW and doesn't work fine with CFW.. then..?
I have no problems with ExFat on OFW..

Except it can happen in OFW, it’s just not as common

Im Using exfat all Times, no issues at all. These issues existed on Early switch homebrew.

Stop spreading this. The bug is present in all versions of Horizon currently in existence, and has nothing to do with the homebrew toolchain. It is not fixed. It cannot be fixed without hacking FS up.

exFAT works on my machine. Maybe you guys should stop using shitty homebrews and actually play games.

It also affects official software (just less common due to official software not doing reads/writes to the sd card as much)...

Then show prove that exFAT was the cause of corruption and some other bullshit

I’ve had corruption with exfat with both homebrew software and official software in OFW... I have had 0 corruption since switching to fat32

great proof. If I break my sd card into two it's probably exFAT's fault.

Wot? I’d say having shit tons of corruptiom with both CFW and OFW while using exfat, then having no corruption for 9 months straight after Switching to fat32 is solid proof...

I've used exFAT since July last year and haven't had any corruption. There is my proof that exFAT doesn't corrupt shit. Is that how it works?

I’m just gonna guess you don’t use shit that reads/writes to the sd card

If you don't trust SciresM, fincs, yellows8, profi200 or TuxSH on this I don't know what to tell you.

It's a fact that a corruption bug exists. It manifests exclusively with homebrew, because homebrew reopens files on the SD card all the time, in contrast to official software which only does so once when the game is launched (after the romfs is mounted, nothing takes this access path)

@ImLEBrAn : Yes, we homebrew developpers are morrons. You, are alright, it's better to glorify exFAT because it let you play your f**.. isos.

lincruste · May 27, 2019

I remember Atari ST fanboys, I remember Genesis and XBOX fanboys too, but I didn't think I'd live long enough to see ExFAT fanboys.

Yep and that's what 99% of the people that hack their devices want. Free games.

At this point, I wonder why Atmosphere developers even bother supporting us 'minorities' who just want to play homebrew and emulators, when their hard work is being put to waste on (particularly) shameless pirates using their software against the dev's wishes.

And not just shameless pirates; ones who outright stare at the blinding truth, then turn around and say "I don't have problems, so they don't exist."

We lost Rinnegatamante over this.

i use exfat and retroarch and never had any problems.

but to think you want a good emulation system using the switch and retroarch, think again.

your better off getting an android or pi set up.

resources of the switch are still limited and emulation is still pretty shit, so save yourself time and go for a platform that has had years to evolve.

Homebrew Question Retroarch + exFat = corruption?

Did you had any corruption issue while using Retroarch?

Yes

No
