No, nand backups are specific to the individual console.
I have a few people who are interested in having me "hook them up" on the homebrew/backup game setup. They all have the same 4.2 that I have. If I can get bootmii installed as boot2 could I just load the nand backup from my machine to do the rest of the work? I have done mine in so many different steps over a long period of time. It's not all fresh in memory. I have read the 4.2 hacking guide (which is very impressive, thank you for that!) but I am just looking for a shortcut. Will this work?
yes, as each nand is encrypted differently / corresponding to chipset on your specific board. oehm something like that, don't do it
I don't think bootmii will allow you to do it, and would give you an error before a brick-situation could occur.
I actually had this question, but I was going to ask when the time came to need it. My friend will be buying another friends wii, one that is equally as old as mine (1st gen, bought new first christmas) and there are many save files on my wii that are his anyway. I thought this might be easier then running a softmod and unlocking and copying the saves. If it won't work, then that's good to know.
Give credit where credit is due. If it helps you, click "thanks" on ANY guide I link.

I think if you install Priiloader and enable the game hacks (de-encrypt or otherwise unprotect the game saves) you can use game save manager or something like that to transfer them. IDK, I've seen threads on this before, apparently it's doable (but as stated, I have no direct experience one way or the other).
