AFAIK hactiol supports nax0 decoding. Also on switchbrew.org that file format is described in details.

hi, I'm trying to dump a game file that's 5gb, my SD card is formatted to FAT32, I selected "yes" for the file splitting option, but I couldn't the dumped file in the romfs folder (or anywhere else) but I did notice the 5gb of space was used.
Where is the split file located at? Thanks!

Hello. I am trying to dump FETH (E-shop) and I was able to dump all the updates/dlc but when I try to dump the base game it tells me

readNcaDataByContentId: failed to read 3072 bytes block at offset 0x0000000000000000 from NCA "8e079aa8f8ef2e83e5230db02b65b488"! (0x00000A05)
dumpNintendoSubmissionPackage: failed to read header from NCA "8e079aa8f8ef2e83e5230db02b65b488"!

I did my best to try to find a solution and I found someone with a similar problem from years ago but it was just a matter of updating, I have updated nxdumptool, hekate, atmosphere and Lockpick_RCM and it has made no difference.
Any help would be much appreciated.

Hello @DarkMatterCore

My sd is formatted to exfat, so it's supposed to support files bigger than 4gb (I'll soon turn it to fat32, i keep it at exfat while dumping things).
I dump a lot of my cardridges (arround 40) but all my games above 4g are splitted to 00 and 01 files despite my sd being exfat.
How do I change that to get directly the xci file?
How can I safely (meaning, not currupting the dump) merge all the 00 and 01 file into an xci file ?

Thanks
(I'm using the latest Actions build https://github.com/DarkMatterCore/nxdumptool/actions/runs/7371908949)

Hi there.

Rewrite builds no longer support writing files with sizes >= 4 GiB. Instead, we replicate actual Horizon OS behavior by writing ConcatenationFile entries if the size for a file is >= 4 GiB. Futhermore, SD card filesystem changes are always committed/flushed after closing a file that was written to.

I still strongly suggest against using exFAT-formatted SD cards. If possible, just use USB dumping by connecting your Switch to a PC and running the Python host script I made (requires an extra Zadig driver installation under Windows); or use a USB mass storage device with a exFAT/NTFS/EXT partition connected to the Switch. You can change the "output storage" option available in multiple menus from the rewrite builds to control this behavior.

You can join the numbered files on a Windows PC by running "copy /b * game.xci" on a command prompt placed inside the directory where the numbered files are saved.

Hope that helps.

Thanks!

I had to delete my PayPal account and recreate it from scratch some time ago, after migrating to Spain. The donation links from the nxdumptool repository should work properly. If they don't, feel free to DM me about it.

Yeah. Getting used to Spain hasn't been too difficult, luckily. I already have both residence and work permits. Things are not perfect, but I'm objectively better than before.

This may be a newb question but I've been using the tool to rip my own carts into XCI files and selecting to dump the Certificate, yet after a couple of dumps I noticed the Certificate folder is completely empty. Are these stored elsewhere or is there an issue going on?

Where is the split file located at? Thanks!

it would be in the nxdumptool folder thats located in the switch folder I believe

That's where I'm looking. The XCI files go into the XCI folder just fine, it's that the Certificate folder remains empty.

The old version of this app had the ability to dump romfs and exefs, but im not seeing that option here anymore, anyone know if this is still possible?

 

[GBAn00b1e]

I would like to dump my games and remove any unique identifiers during the dumping process. I plan on installing it on my own switch, but I would like any and all unique identifiers removed to mitigate the risk of banning if I lose the console and someone extracts the games. Anyone know the options I would have to use to accomplish that?

sorry for reviving an old thread but does dumping create these files?

Yes.
The readme also answers your question.

Hello
I've been trying to use the re-write version to get ahold of the RomFS data for Tears of The Kingdom for a while now, by dumping the Gamecard data. I've been able to get the full .XCI dump (29 something GB) and the trimmed down version .xci (16.3GB), but the Romfs dump extraction keeps being stuck at 0%, even after 20 minutes!

I am getting rather frustrated with this. I need the damn Romfs data for a program I wanna use to try and create mods for the game.

Any advice or ideas as to why I can dump the entire game but not specific files?

 

[masagrator]

Do you run nxdumptool in Application mode/title takeover? ToTK is the biggest game in terms of raw file count, so it may struggle with storing all those informations and handling extraction in the same time in Applet mode.
