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

Here is the video version.


Requirements
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?)

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

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

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

What is the purpose of python ? We can run .bat and RomFS Builder without it
Click to expand...
Removing first 1000 bytes uses python.

How do I install Neo x though I tried to brake it but I get black screeen
Click to expand...
IDK, I think you must put the files given with the hack. Not sure how Pokemon neo works.

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 ?
Click to expand...
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.

  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s

  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
  • DinohScene @ DinohScene:
    run h2testw on it

    when SD cards/microSD write speeds drop below a meg a sec, they're usually on the verge of dying

    Samsung SD format can sometimes fix them too
  • Purple_Heart @ Purple_Heart:
    yes looks like an faulty sd

    @Psionic Roshambo i may try that with my dead sd cards
