    i have a 3ds rom (which I own), but since I don't bother with hacking hardware I simply acquired a "backup" copy of my 3ds game, already decrypted.

    I have already done extensive rom-hacking on the decrypted 3ds rom; I have changed stuff like spells, items, etc. I've done all of that using a hex editor (crystaltile2).

    however I have recently noticed that-- (ok, bear with me: I own this game also on Steam PC, AND, I *also* own yet a another port/version of this game on PSP)

    --ok, I was saying this: I have extensive knowledge of all of the files packaged inside this game. I've hacked this game a lot, on pc and on psp.

    this means that I know when the 3ds rom which I have been hacking via hex editor is suddenly "not showing me" certain stuff (game data such as, in this specific instance, the skills/abilities lists, etc); I know exactly where those are and how to find them (pc and psp versions use same file types, same structure, etc)-- but, for whatever reason, the 3ds port of this game has that specific info I want to edit "under wraps".

    I can see bits and pieces of the information I'm looking for, but it's mixed up in garbled/scrambled crap which makes me think it's a bit of compression. It looks like the kind of compression you see on NDS roms, i.e.

    (in hex field) (text field)
    FF FF FF FF FF nXXX***THINGIWANTxIIII
    FF FF FF 82 71
    FF FF FF FF FF

    so on and so forth. anyway, could anyone please kindly guide me towards a tool which will allow me to at least open up the 3ds rom (btw, I've simply been hex editing the rom directly) and view its files? I already know what it will have: CSV files, more CSV files packed inside .BIN containers, etc.

    And, best case scenario, to hopefully also extract the files or at least "decompress/decrypt" the rom so I can simply continue editing the stuff I can't right now.

    I tried every file explorer but it doesn't allow loading a .3ds rom.

    I tried a tool which when you drag and drop the .3ds rom file on top of its executable it pops up a CMD window, and after a while it plops out a file called "EncryptedROMFTS.bin".

    I tried hex-editing that .bin, to see if I saw anything I recognized, but no luck.

    Thanks to everyone in advance!

    I found what I needed! It's a tool which completely unpacks the contents of a 3ds rom. ToolKit 3DS "Form" I believe is the name of it!

    I extracted exactly what I expected to find: the same CSV files and the same .BIN files inside the PSP/PC ports of this game.

    ...unfortunately I still have no idea how to "access" the "compressed/encrypted" game text that is all scrambled! in the PC/PSP version, for example, you can control + F search for the word "S A M" (in double-width), and it'll go directly to the spot iwhere the character classes are found.

    in the 3ds rom version of this game that info, all of those "sections", are nowhere to be fonud except mixed up in alphabet letter and symbol soup.

    thanks anyway, and thanks to anyone who may be able to help.

    i'll check with my copy of dw7. i haven't touched it and this is a perfect excuse to open it up. (i finished it on ps1 already). i'm not sure what script files specifically you're after but i'll try to extract what i can and see what happens i'll bump the thread if i have anything
