Download & unzip hactool from the following link
https://github.com/SciresM/hactool/releases

Extract the main file from Section 0 in the Program nca file with NxFileViewer

cmd
hactool.exe --uncompressed=main_uncompressed -t nso0 main

If you open the main_uncompressed file in the Hex Workshop Hex Editor, you can see the contents in a composite form.

Click on the binocular-like icon at the top


Change Type to Text String, type 【RightAnalogStick】 in Value, and click OK.
or type 【25G/】 in Value, and click OK.
This means to search for RightAnalogStick in the text (characters).
This is because the seed for the other game I referred to was found around the RightAnalogStick text.
Depending on the games that will be released in the future, it may not be in that vicinity.


In the example image, you can see the string 25G/xpvTbsb+6 just above it
This is the seed needed to expand alldata.bin and alldata.psb.m

Extract the alldata.bin and alldata.psb.m files from Section 1 in the Program nca file with NxFileViewer

Download & install .NET Core from the following link
https://dotnet.microsoft.com/download

Download & unzip MArchiveBatchTool from the following link
https://github.com/farmerbb/RED-Project/releases

Copy the two files "alldata.bin" and "alldata.psb.m" into the MArchiveBatchTool folder.

cmd
MArchiveBatchTool.exe fullunpack --keep alldata.psb.m 【zlib】 【seed】 64

zlib is a compressed format, and I think it's usually zlib, but it could be different for some games.
For example, for the Mega Drive Mini, it was zstd.

Example
MArchiveBatchTool.exe fullunpack --keep alldata.psb.m zlib 25G/xpvTbsb+6 64

It will be extracted in the alldata.psb.m_extracted folder

Most of them are
alldata.psb.m_extracted/system/roms
folder, which contains the rom files for retro games and sometimes bios files

    @SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme
  • The Real Jdbye @ The Real Jdbye:
    but that's a long shot
  • The Real Jdbye @ The Real Jdbye:
    i think only the red mario kart edition phat was v5
  • BigOnYa @ BigOnYa:
    A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."

    Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.

    @BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.

    The issue is DRM

  • cearp @ cearp:
    You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60

    :rofl2:
  • cearp @ cearp:
    still, I agree physical media is nice to have. just pointing out the issue is drm

  • rqkaiju2 @ rqkaiju2:
    i like physical media because it actually feels like you own it. thats why i plan on burning music to cds
  • cearp @ cearp:
    It's nice to not have to have a lot of physical things though, saves space

  • AncientBoi @ AncientBoi:

  • SylverReZ @ SylverReZ:
    @rqkaiju2, Physical media is a great source for archiving your data, none of that cloud storage shiz.
