Hacking A little confused, will my r4 work with latest firmware?

[DarKRevival]

Hi all

Sorry for asking, but after reading some more about these cards I've only got myself more confused than ever. I'm currently on an old firmware on my 3ds 6.xxx can't remember exact version, and the R4 card I have just bought is working great, but it's my daughters 3ds and she may accidentally update the software to the latest version.

So basically if I updated my firmware today to latest (uk) will it continue to work?

Thanks a bunch

This is my card:

It will work without having to update it.
