Hacking NDSTokyoTrim - batch trimmer with wifi detection

[Kurt117]

i think the largest is 4gb,like bravely default and Resident Evil Revelations........

What's the largest 3DS rom you know of? I wonder.. since trim offset is a 4-byte address which can be max 4GB, what happens with roms much larger than that.. need to check if they use a 64-bit integer or how they handle it...

4 294 967 296 bytes.

Wow, I can finally retire my GBA and NDS rom trimming tools for this one, thanks and great job.

Ok here's a new one that handles 4GB files

Moved to beta phase. Take a look at the Roms DB area.

Can't get it to work on my Win 8.1 PC & Win 2012 R2 server. Always get runtime error.

nice job.....
it would be really nice if you could add an "un-trim" option,is it possible?

Why would anyone want to un-trim a rom?

Works fine here in a VM. Maybe you got Avast or Norton?

to patch the rom for online play
seems like patching trimmed roms is not possible(it's possible but for some reason the rom won't work),so we have to patch the rom first and then trim it......

I've disabled Symantec Endpoint Protection on my PC & MS Security Essentials on my server but the problem is the same:

Is that a 3DS thing? can you ellaborate, what's exactly done to the rom?

Do you have DEP turned on for all programs?

Nintendo usually uses media units (0x200 bytes) to address offsets in rom headers. That's how they handle > 4 GB roms. They can go higher than 4GB even though there hasn't been one yet.

Yes I do. But why your software is required to disable this protection?

It seems to be an issue with this

I use this to load the 7zip and unrar DLLs from memory rather than having to extract them first to disk, this seems to trigger the DEP error.

Here's a DEP-friendly version

Now it's working for me too, thanks a lot.

Does your trimmer support trimming of .3dz files?

 

[BrianTokyo]

Does your trimmer support trimming of .3dz files (aka online patched ROMs)?

I added 3dz support, but it's mostly untested.
