Hi all,
I upgraded an nsp based game on February 1, 2020 and I don't like the update changes (version 1.1) and want to return to the prior version 1.0.
I have several NAND backups from before the game update was installed.
I'm using SXOS 2.9.3.
I clearly don't understand NAND, emuNAND, and save game files because I thought this would work.
With the game update installed, I was on 6.2.0 for official firmware and 9.1.0 for emunand.
I did a new NAND backup before doing anything.
Then I grabbed a new microsd card just to keep the original intact and untouched.
I restored a NAND backup from December 2019, prior to ever upgrading the game (it only had the one update).
I booted into sxos and created a new emuNAND with a hidden partition which required reformatting of the microsd card.
Now the official firmware is 6.2.0 and the emuNAND is 6.2.0.
I installed the game from the nsp but it does not fully appear on the home screen. It shows an empty slot with a spinning wheel and won't launch. In emuNAND, system settings, data management, manage software, it shows a grey question mark icon and says 'not played', 260MB. When I go into Checkpoint and the Manage Save Data option in settings, no save data for the game exists. I assumed that I would lose my save game data by using a new microsd card with the reformat.
Is my goal possible with SXOS?
Is there a step that I am missing?
UPDATE:
Well, I was playing around in SX Installer 3.02 and was looking at the game. I got a dialog box that said this game is not compatible with this firmware version. So I updated the emuNAND firmware from the newly created 6.2.0 version to 9.1.0 and the game works perfectly. I'm playing on version 1.0. I lost all of my save data, of course, but that was known and expected. I'll just have to unlock all of the items again.
