So my 64gb SD card became read only and because of that if i try to load up the game it gives me a message "The saved data is not compatible with this version, so it can't be used. Refer to the electronic manual for details. Ver. 1.4" i have not done any hacking, modding, or save data transfers. I talked with sandisk and it is a security feature that activates when the card thinks it was tampered with. I've never removed it from the console since it was in there. I truly got screwed on this one and did nothing wrong. I'm doing research myself to try and find a way to get my save data accessible and transfer my pokemon to the official bank, if i need to restart my gameplay that is fine but i want my pokemon that are in the save data. Currently the only possible hope i've found online is using a homebrew modded 3ds to access the save. im concerned if i homebrew my 3ds or another one that i wont be able to get my pokemon into the official bank. If anyone can help with this i would be greatly appreciative. I should mention the only thing i have tried so far is transferring the data to another sd card and inserting that. when doing so everything works (other games) except for omega ruby save. thanks again to anyone willing to hear my dilemma, and all the thanks to any help.

Sounds like this tripped the
beloved anti-feature:
Anti Savegame Restore. When starting a game using that feature the 3DS verifies that "Secure Value" on NAND fits to the save version.
I guess on starting the game something gets written directly → Secure Value changes. Since the SD went read-only the change was never written to SD… but the NAND does contain another value →
BOOM!
Sounds like time for
https://3ds.hacks.guide/ Deleting the secure value with FBI should make the game accepting the save once again. The custom firmware installation does not interfere with online features such as Pokemon Bank. This will continue to work.
With an ntrboot cart starting FBI (or GodMode9) is possible without permanent CFW installation. Since the save is encrypted it is not (easily) possible to use another console for this.
============
Incidents like this one are a strong argument for CFW and having full control over our devices. SDs can fail for no reason. A console can be dropped onto concrete or get stolen. Important data needs to be backed up and Nintendo makes this impossible for some titles under the cloak of cheat prevention (and the internal backup function for titles allowing backup is still tied to a single console).
Please use Checkpoint and/or JKSM for backing up important save data from time to time and store it on multiple storage media.

Good luck and have fun!
