ROM Hack Need help with Mario Oddyssey save transfer

[DrZhark]

Hi

I have two switches, one of them is using SX OS dongle with firmware 5.1 the other one is used to play games without any ban worries. On the unmodified switch, I have a couple of save games for Mario Oddyssey, that have my current game progress. I'm wondering if there is an easy way to transfer those save games to my 'hacked' switch that uses SX OS without jeopardizing my un-modded switch

Thanks in advance for your help!

Awesome! I'll try that!

I made a tool.

1.mount user data from nand
2.copy all files from save directory to tool/save directory
3.run.bat
4.you can find gamesave in the out directory

Seems like this could help
