Sorry I took so long to get back with the results.
Yeah so I re-did the process and checked the file and still no-go. I did learn changing the encryption key breaks some(all???) checksum in place ;___;.
Did you test making one for your O3DS 10.1.0-27?
@phase
Have you used
3dsfuse before? If so do you know if it can write/modify complete save files(entire images) correctly(checksums mostly)? Also is it a windows program or a 3ds app?
I Can't confirm anything due to not being able to restore but I can confirm that op's save encryption is the same as mine and that should allow it to work on my cart if it had the right payload for my system.
You do need to have a save dongle to restore these saves, but you don't necessarily need to have powersave.
So to remove the wrapper powersave adds to the save file for use with other save dongles is this (assuming they don't add thier own wrapper/checksums etc)
* I WILL NOT TAKE ANY RESPONSABILTY FOR YOUR ACTIONS BEYOND THIS POINT IF YOU FOLLOW THESE ACTIONS DO AT YOUR OWN RISK. REMEMBER BY DOING ANYTHING NOT INTENDED FOR YOUR SAVE DONGLE SUCH AS MODIFYING A SAVE OR CORRUPTING ONE CAN BRICK YOUR CART YOU HAVE BEEN WARNED.
1. Get a hex editor (I use HxD)
2. Open a powersave save in hex editor
3. go to edit menu and click 'select block'
4. Click the length radio button and enter 9c(hex) or 156(dec)
5. Click okay
6. Press delete on your keyboard
7. Save file with new name to indicate the changes (like 'wrapperRemoved' or 'justSaveFile' etc)
8. Make sure the file length in hex editor has exactly 0x20000 (hex bytes) any more or less and you messed up. REDO THE PROCESS FROM THE BEGINNING OR RISK BRICKING YOUR CART.
9. Restore your new save with a non-powersave dongle (like r4i save dongle or NDS adapter plus etc...)
10. Test
You can also check the save file (encryption key, specific files, and etc) using
3DSExplorer (rencrypting or changing the encryption needs a different program)
@Ignisflame
Can you help me out by making a 2.1 OoTHax for 9.9.0-26u because we have the same encryption key on our OoT cart?
Edit--
There are alot more save dongles than that like r4i save dongle, NDS adapter plus, etc. Even a SKY3ds(granted it saves just like a real cartridge and gets encrypted idk if it does tho) could use these files.
