What happens if i use the wrong SD Card? [solved]

[aezthetic]

Basically, I have two wiis with Riivo on them.
One is my dad's, one is mine.

See, I have a SD card with all the regular files on it (riivo, private, codes, app, bootmii ETC.) but im not sure if its the files for my wii or my dads. So what happens if i use the sd card with the files for my wii on my dads wii? Will his wii crash or will it work normally? Sorry if this is a stupid question, but its been bothering me alot and im in no mood to break my dads wii.

(Sorry if this is hard to understand, im not good at explaining things x_x)

One would need the Homebrew Channel to even be able to access them on the Wii. Unless there's a file in there that is read when you start up the Wii (which I don't think there is), you should be fine.
