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!
