Edit save file on sysnand

[gateronblue]

I have an unpatched switch, sd card ,rcm jib, pc. I want to mod my switch so that i can edit s/v save files, but i want the save files on my sysnand. Im familiar with pkhex and pokemon legality and stuff, but im getting mixed information about how to avoid bans, some info suggests you are unlikely to be banned, others tell me that the log files make it almost certain that i will be banned, just want to check here and see if there are maybe any guides or information on this topic

If you simply boot Atmosphere (the cfw which will allow homebrew to run) with the fusee.bin they provide (no sigpatches or any other modifications on your sysnand) you'll be able to launch homebrew such as Checkpoint to dump your save games.

I do this with the Switch in aeroplane mode, then power it off once the saves are dumped. In addition I'll remove any files relating to Atmosphere from the sd card before the Switch goes back online.

Perhaps I’m a little over cautious, as I know people who have done a lot more on the sysnand and are not banned either. It's about how much risk you are willing to take.

The above is probably the easiest way to get started for only save backups and such, which is all I’m really interested in. If you want to do any more than that i'd create an emulated nand to be safe and ensure this NEVER goes online.

If you want to go all out and create an emulated nand this is probably a good starting point: https://switch.hacks.guide/ - read that guide a few times from start to finish and understand what you are doing, before you do it.

alright thanks, good to know for backups, can i get the save back on the sysnand in similar fashion?

You can, you'd just copy the save back to the same location on the Switch's sd card and restore the modified save with Checkpoint.
