I tried using JKSV, it crashed on me, so I've been using Checkpoint and have no complaints. Basically, use whichever works for you. Or just works, period.
I think so, but can't remember for sure, honestly. Right after this happened I tried Checkpoint and basically had no need to put more time into figuring it out since it did everything I needed it to do.

You need to use these homebrews in Title mode (holding R with any game), rather than Applet mode (running it via Album). Even Checkpoint works better with it.
For what it’s worth I’m on 12.0.3 and JKSV works fine in either Applet or Full RAM mode. It’s only when @JustJay mentioned his current FW version that I thought this might be useful.
I'm a personal fan of Checkpoint. I think I used JKSV one for backing up Animal Crossing since Checkpoint can't do that, at least it couldn't at the time. I don't know if that was fixed or not.
