Homebrew [Tutorial + Scripts] Usage of HANS.

[PabloMK7]

I'm making this tutorial so you can easily generate a proper romfs to use with hans.

Here is the video version.


Requirements

• Python 2.7 installed
• This tools I made
• A encrypted/decrypted rom in 3ds/cia or an actual romfs.bin (Use this thread to dump and decrypt your rom)
• HANS (included on starter kit)

Procedure

1. Extract the tools.
2. Put the 3ds/cia/romfs.bin in the same forder (if encrypted, put the romfs xorpad there aswell.)
3. Run extract_romfs.bat and follow the indications.
4. If everything goes correctly, a romfs folder should be created.
5. Edit whatever you want in romfs folder.
6. Once you are done, run Romfs builder, a tool made by @SciresM.
7. On Romfs Builder select the romfs folder and click go, after a bit it will prompt you to save. Save it as whatever.bin but in the same folder as the bat files.
8. Run gen_romfs.bat, it will ask you for the whatever.bin file name, and then for the low titleID (last 8 characters of titleID) of the game you are trying to use with hans. If you don't know it, you can run hans with the game you want to hack and it will show the titleID at the bottom of the config screen.
9. If everything goes fine, a titleid.romfs file will be created. Copy that to SD:/hans and you are done.

Notes.

If the romfs folder is empty and/or the tool returns an error, it will be copied to log/error.txt. If you can't manage to solve the error, post it here.

Only decrypted cia has been tested, so other modes may not work or be buggy, sorry about that but I don't have much time to test.

I would really like a note about what are exactly .3ds, .cia, romfs.bin, exefs.bin (even .3dsx)
What is the idea of this encryption. (which is encrypted? how do we use it?)

3ds/cia -> roms.
romfs -> rom files
Encryption -> Games are encrypted, so nobody can see them. There are several ways to decrypt them.

Awesome testing these tools out.

well done, but the extractor claims my romfs.bin is not a valid file

Ah... it may be because there are spaces in the filename. If that isn't the problem, check the error log (log\errorlog.txt) to see what happens. I'll try to solve that.

I'll try to record a video tomorrow... if I have time...

What is the purpose of python ? We can run .bat and RomFS Builder without it

 

[Xen0]

Thank you for this! I'll try later with my romfs from Pokemon Y because I couldn't find a decrypter for the file...

How do I install Neo x though I tried to brake it but I get black screeen

Removing first 1000 bytes uses python.

IDK, I think you must put the files given with the hack. Not sure how Pokemon neo works.

 

[MasterLel]

Can't we do it manually with hxd for example ? gen_romfs.bat will just rename the file, or it will also strip out the first 1000 bytes ?

Actually it only renames and removes 1000 bytes, if you know how to do that. There is no need to use this tool. I made it for people who has problems with hans.

 

[TheFlamingFurret]

It's stuck on
'saving romfs\a\0\0\8...'
Is it meant to do this?

Nevermind, it continued just as I posted ._.

get a blackscreen after using this tool with pokemon x for pokemon neo x. for the last I checked at hans rom fs -> SD to yes and then I pressed OK and i got an blackscreen..

o3ds 9.8 via ninjhax

 

[ant888]

Blackscreen for me too NSMB2

 

[PabloMK7]

It seems to be a problem with hans... I still remind you to put it at SD:/hans and not SD:/3ds/hans

I did put it at SD:/hans

 

[PabloMK7]

I did put it at SD:/hans

Then the problem is hans related. We will have for smea to solve it or at least release the source.

Works with neo x thank you.

 

[Justin20020]

Works with neo x thank you.
