Homebrew [Release] Stupid simple 3ds python tools

froatsnook · Nov 24, 2014

As much as I like you guys, I try to avoid downloading random binaries to manage 3ds files as much as possible. I wrote a couple python scripts with the goal doing common tasks via drag and drop in windows explorer. They work for me. Maybe they'll work for you.

At the moment I have python 3.4 installed. They might work with older pythons but I haven't tested it. For python 2.x, at least a future print function import would be necessary. If there's any interest I'll fix them up.

rename.py:
Choose your file name format near the top of the file (mine is

Code:

target_format = "{id} - {name} {region} {filename}"

). Then drag and drop roms onto it. It will download the latest XML from 3ds.essh.co when it doesn't recognize a rom.

crc.py:
Drag and drop a rom onto it and it will print its CRC in the console. Useful for verifying untrimmed roms.

trim.py:
untrim.py:
Here you need rom_tool.exe in your path (or in the same directory as (un)trim.py). Drag and drop to trim, or drag and drop to untrim. The file is modified in place. But according to rom_tool.exe, it's a lossless operation so that shouldn't be an issue.

rename_save.py:
Drag a save file to rename from 0004000000XXXXXX.sav to something readable. Drag it back to change it back. Since titleids aren't unique (e.g. Pokemon X), you might see the wrong release name/id (but it should be sufficient for figuring out what game it is). I didn't test it on too many saves, so let me know if it doesn't work for some game.

Do you think can auto extra title id and rename the .sav file with titleid to rom file name?

What?

Do you mean rename 00040000000XXXXX.sav to Pokemon.sav or whatever?

Timburpton · Nov 24, 2014

Yes. For example auto rename 000040000000.sav to Pokemon_Omega.sav when detect Pokemon_omega.3ds titleid as 000040000000

Yeah I could do that. I might have time tonight

Thank you so much. Auto rename other way round will be much thank you too.

I uploaded a new version. I hope it's helpful.

The script work great after update python 3.4.2. It no work 2.7.8.

One other thing, how I modify rename.py so it'll rename format to Pokemon_X_USA.3ds instead of the 250 - Pokemon X - USA -AEVAD.3ds

froatsnook · Nov 25, 2014

First change target_format (top of file):

Code:

target_format = "{name}_{region}"

then you have to change sanitize_for_file_name (line 245). Something like this:

Code:

def sanitize_for_file_name(text):
    text = text.replace(": ", "_")
    text = text.replace(":", "_")
    text = text.replace(" ", "_")
    text = text.replace("!", "")
    text = text.replace("?", "")
    return text

Timburpton · Nov 25, 2014

Thanks! That works!

I checked your python script and it retrieves the xml from 3ds.essh.co. Some titles not show up like some eshop games. Any way to add them? I think can edit titles.xml but your script fetches the title.xml each time.

Is it just new stuff that isn't showing up?

Timburpton · Nov 25, 2014

For example denpamen does not show up and it's not that new

Do you mean 'THE "DENPA" MEN: They Came By Wave USA'? That is on 3ds.essh.co. Maybe you just need to remove the quotes in the file name:

Code:

def sanitize_for_file_name(text):
    text = text.replace(": ", "_")
    text = text.replace(":", "_")
    text = text.replace(" ", "_")
    text = text.replace("\"", "")
    text = text.replace("!", "")
    text = text.replace("?", "")
    return text

This work good. Much thanks.

Excellent!
Thank you very much, was messing with the weird gui binaries with little luck and this did exactly the things I needed

why make a python script for checking the crc? why not just type 'crc32' in terminal if you are going to type out the python command?
but thanks, a python trimmer can come in handy! although i guess rom_tool would be faster because it is in C. it's hardly a random binary, it's made by 3dsguy and is open source, no need to reinvent the wheel and worry about things

Hey froatsnook,
Can you make a python script to replace private headers in the sky3ds template? They distribute an executable but would prefer python but I dont know how to do it

https://docs.python.org/2/library/string.html

Basically the 16 groups of two characters (hex bytes) above the 48 groups of FF need to be replaced by your private set of 16 hex bytes

Here is a snipit from sky3ds latest template.txt

Code:

So if my private header hex bytes were =

Code:

11 22 33 44 55 66 77 88 99 AA BB CC DD EE FF 00

Then my template.txt would look like the below

i'm pretty sure there already is a python sky tool, made by someone here, did you see/search for it?

-- or, did you see it and it is not what you want?
