Just use cia files instead. They're trimmed by default.
Thanks for the info!
But if he's aiming to save up space the safest and fastest solution would be to use cia files instead of ROM'S.
i think it is nice to be able to move the gw to a different 3ds and play the games there, like a friend can use my gw card with my games on it, with cia we would have to install the actual cia etc. - especially for card2 games where the save is stored in the rom, i can move the gw cart to any of my 3ds and play my same pokemon game + the save
Now I think about it if gateway ever support the newer 3ds xl then this will also make it a lot easier moving over.
yes, since you won't need to export all the saves with savadatafiler etc i didn't think about that too, nice idea
I recommend 3DS to CIA. NDSTokyoTrim doesn't seem to get updated any further(although it's been a long time since I last checked)
You can find it on the maxconsole forum.
The name is just misleading, it has super/trimming feature. And it supports Card2 games too.
i personally don't think it can get much easier than rom_tool - if you are happy with command line applications
