Seems pretty worth it to Trim for those who do not have big Micro SD's.

Wait, can I remove system updates from game backups and still use them in Sky3DS? Or will this introduce an incompatibility? Can't test atm, still waiting for my Sky3DS card.
Darn, and I thought that would be a way to be safe from unwanted system updates on Sky3DS.You can only trim unused space, any other will modify rom data itself and 3DS won't load that rom
Is it possible to swap out update partitions with say, a lower version of an update? An example would be:
>Have 7.2U 3DS
>Wanna play Smash, but it has 8.1U on the ROM
>Use tool to remove 8.1U update
>Use tool again to inject 7.2U replacement update
>Launch Smash without being asked to update to 8.1U
I'm attaching a zip that someone posted somewhere on this forum, that contains a rom_tool build that works fine for me. If it doesn't work for you, my only other thought is: is your mac a 32-bit one? I could never get rom_tool working on my old 32-bit macbook, tho it works fine on my newer 64-bit macbook air. If you still have trouble, there's a python script somewhere that will work, I should be able to find it for you.I tried multiple times to trim a 3ds rom on my Mac, but I always get the following errors: "Permission denied" or "Segmentation fault:11". Can anyone explain in detail how to use this tool to trim a rom with the Terminal on a Mac, please?

It provides instructions when you run it, it's just:hey, I'm trying to figure out how to use this tool. how does one use this exactly? really dying to trim a couple ROMs for my 3DS. thanks
It provides instructions when you run it, it's just:
rom_tool -t <filename>
If you're not familiar with the command line, then I guess...
1) Run "Terminal" from /Applications/Utilities in Finder
2) Drag rom_tool from Finder, wherever you unzipped the file I posted, into the Terminal window
3) Click on the Terminal window and type -t (dash then t) followed by a space
4) Drag the .3ds rom you want to trim from Finder into the Terminal window
5) Click on the Terminal window and press return
