Thanks Atrius; I wasn't expecting it to be easy, but I also don't expect it to be that difficult either. Since saves are like a database, data can be new and old data can be removed from one revision to the next, as long as I know what the differences are I can somewhat reliably determine what needs to be rolled back. Beyond doing a bit by bit comparison of the file formats myself, I was hoping someone out there would have hit this too and could point me in the right direction

Hello, I have an interesting problem: I recently installed Pokemon Brilliant Diamond on my modded switch and have been playing for some time. I eventually wanted to patch the game from v 1.1.0 to v1.3.0, so I did and the game was working fine. Now, I want to mod the game but needed to downgrade from v1.3.0 to something older such as v1.1.3. When I re-installed the older base version and cleared the update requirement in DBI, the game simply does not load. The nintendo switch splash screen appears, then nothing but a black screen. I posted in another forum here: https://gbatemp.net/threads/switch-noob-paradise-ask-questions-here.488277/post-9844602, where another user suggested deleting the save file. Deleting the save fixes the black screen issue, but I lose my progress. Using PKHeX, I was able to open the save backup just fine. I tried adjusting the "SaveRevision" property from "52" to "44" which changes the "SaveRevisionString" property from "1.3.0" to "1.1.0". After restoring this modified save, the game no longer boots to a black screen but, after the title screen the game complains that the save data is corrupted and must be deleted. I need suggestions for how to "downgrade" the game version for a save file so I can go back to an older version of the game.
