    Hey Guys, right now, I want to customize "Harvest Moon - A new Beginning" (my thread about it)
    And there are some .arc-files which I can open with EveryFileExplorer.

    And now I want to know: is there a way to unpack and repack .arc files or possibly, create new .arc files with own files inside of it?

    There certainly is a way it's just not that easy.
    If I recall correct EFE is open source right?
    Figure out how it reads the .arc format, write your own extractor and repacker based on this.
    Will save you time figuring out the format.
    That's about the best you could do.
    There will usually be a header, followed by a filetable, size descriptions and so on.
    Usually a stream reader+writer are used for such operations.

    Then your only option is to ask someone who knows or wait for such a tool to appear.

    What is the header of that .arc file?
    .arc is just a file extension, not file format, AFAIK. Most likely it's just a file container (like DARC, NARC, U8, RARC, whatever) with the .arc extension.
    Or, maybe, you can just replace those .bclims in EFE?

    It's a "darc" header. With EFE, I can export bclims but not insert them back o_o

    No one who could help me with this? I really don't know how to create such a tool >_>
    It's weird that EveryFileExplorer and 3DSExplorer1.5.3 are able to read the files but not to reimport files :/

    A QuickBMS Script should be enough for export and reimport files from darc-files

    Open it with EveryFileExplorer, choose File -> Save As..., then choose the PNG format in the dropdown list. You can also use png2bclim

    Yes it can be done.

    3 things are needed:
    darc tool
    python 2.7
    png2bclim

    1.extract the arc with darc tool I believe
    2.convert bclim img to png with png2bclim
    3.edit png
    4.run edited img through png2bclim
    5.and use darc tool to inject newly made bclim that will create a newly named arc file.
    6.replace this new arc with the old one in the romfs folder and rebuild rom or use layeredfs

    may be rusty on directions been awhile since ive done it.

    While we're on 3DS image formats, any news on the .tex format? It's used in Cave Story eShop, for instance.

    Gonna try it in a couple of minutes!
    Thanks for the help ;)

    I saw that, wrong/different type.

    And I know what the images are, as the EUR CIA I downloaded uses .png, but I need some way to convert png to tex as the USA eShop version uses .tex.
