I meant more like accessing things with an out of date console I would have thought would have errors and glitchesYeah, it has consequences of saving your console for hax and avoid having to update if you don't want to.
Not really. There really hasn't been any reports of stuff like that since 9.x. Probably before that, but I wasn't aware of it back then.
If you just copied the Nintendo 3DS folder, then no. If you used JKSM to export your save, then yes. The saves in Nintendo 3DS is encrypted with console specific encryption key. Without that original console the saves come from, there is no way to use the saves on any other system.
Don't play those games, but that means it doesn't use that for save. Some games like Fantasy Life use ExtData for save, but most games don't and some use both Save and ExtData. I'm assuming you have saves to export. It also says that when there's no save data. Make sure you're using the latest version of JKSM from https://github.com/J-D-K/JKSM. The latest version is about a month old.
I'm not sure right now. I've been basically working almost everyday the last few weeks and this project isn't exactly the first thing on my list of things I want to do when I get home unfortunately.
I don't see it in the CIA version. Only the option to change play coins to 0 or 300.
