    You need to have a 3ds capable of running decrypt9 (a ds on 4.5-9.2) in order to decrypt roms. Then you need a tool to extract the files (search on here for that).
    edit: dont rely on video guides, they are usually outdated and bad

    This link here will explain to you everything you need to know on how to get a hacked 3DS - https://gbatemp.net/threads/full-st...u-need-to-know-includes-otphelper-now.417606/

    The first link I gave you will show you how to run the software you need in order to decrypt the roms so you can view them as needed. Finding already decrypt roms may be possible though I wouldn't know where they are and even if I did I couldn't give you a link anyways.

    No afterwards you will have a rom that you can view the files of by following this guide - https://gbatemp.net/threads/3ds-rom-hacking-translations-utilities-posting-guideline.377433/

    I never did any rom hacks so I can't help you there.

    the point in decrypt9 is to allow programs to extract files from the rom (romfs and exefs). romfs contains all respurces for the game, and exefs contains code and some other things. After you decrypt (if the rom is encrypted) you need to use ctrtool to extract the files.

    Errrr... After you have your decrypted rom, you can extract it https://gbatemp.net/threads/tutorial-how-to-decrypt-extract-rebuild-3ds-roms.383055/
    ....and "play" with the different files

    You need a 3DS to decrypt the file (to get all the content, data, code, etc.), and you need a computer to extract and view those files.
    Or you can go looking for the decrypted games in *that iso site*.

    fwiw, the 2ds is much cheaper and is most likely going to be on some firmware that you can either downgrade, or use out of the box for decrypting.
