XCI-Cutter tool (Windows)

I just checked the sizes of installed games and they're all close to trimmed xci sizes posted above. Most are above probably because of patches but they are well below the original dump sizes. So I'm guessing Nintendo already trims the digital copies.

You don't seem to understand how this works...

Nintendo does not trim the games, because "untrimmed" is their original state.

The reason cart dumps are that big is because the carts are dumped, not the games are copied.

So if a game is is 11 GB, it still dumps the whole card, filling the other 5 GB of the 16 GB cart with 1111111111... (FFFFFF... in hex).

Once it's possible I'll gladly share a game dump for science to you. Preferably BotW or Mario Odyssey since they are likely the most common games to have a cart for at this point.

That would be great!

Actually i won't need the full dumps. The first 28,5Kb (29184 bytes, including header + cert) should be enough.

My virus program detects this as malware and moves it immediately into quarantine. Anyone else?

I mean...you know what I mean. Digital versions are real sizes with no fat while physical copies have padding, so dumps of physical copies also have padding. If you trim that you should ideally get the digital eShop equivalent. Yeah the process is other way round than what I said earlier but the concept is same.

Would be cool if this tool would also get splitter for fat32, but I guess that won't be possible until xcuter OS is out. I mean, who knows how this OS reads the splitted fies

False positive

Nice script works very well, just any chance you can add option to create a new files instead of trimming the existing one?
like blabla-cut.xci ?

Requested feature has been added.

Xecuter said how to name the files if they are split. I've read a few members here state we can use the numerous file splitting programs available on the web. Obviously no way to test right now though until the SX is available to us.

Saved around 7 Gb. Thanks!

Yes, if xcuter gonna go most user friendly way

Doesn't Wii Scrubber work a little different?
XCI-Cutter doesn't replace garbage data with compressable data, XCI-Cutter trims blank data.
It's more like 3DS ROM trimmers.

In my opinion developer has full right to name created solution however he wants.

It was just a suggestion, of course he can name it the way he wants, it was my nostalgia moment ..

I've implemented splitting. Will upload the new version tomorrow.
I am currently at work (yeah and posting on GBAtemp... i know ^^)

Splitting has to be considered experimental for now.
I don't know if SX OS expects a specific part-size.
I've hardcoded it to 4GB (To be precise: 4.294.967.296 -1 bytes).

Well, figures this tool is super experimental, since we don't have a way to test it~

I wrote a small tool to cut off the unused sectors at the end of xci files. Thanks to the idea of @Arck

View attachment 124299

This tool reads the XCI-Header to determine the full cartridge-size and the actually used space.

Before cutting, it checks if the sectors after the used space/gamedata are really unused (filled with FF).
It refuses to cut, if it finds any data in that area.

I don't know if those XCI-files would run in a backuploader.
But the process is reversable. The tool can be used to restore those sectors
and expand the XCI-files back to the full cartridge size.

Hadn't much time to put this together.
It might crash now and then ;-)

do you have the time to create a xci tool which splits the xci files into a smaller size .....i.e. less than 4 gb each file....

That's what he wrote 2 posts above you, he'll upload that version tomorrow.

Official games downloaded from eShop to FAT32 cards are split into 2GB files. Maybe that's what they'll go with.

Pushed an update with implemented file splitting.

As before:
We don't know if the files are usable by XS OS.

maybe shoot an email to team xecuter to give them heads up on what we need.

I've posted a question over at maxconsole.

At least one guy already got a review unit.

Found used space after gamedata! Aborting!

Why I got this error?
