I didn't put it in a spoiler for no reason.
At least I don't bother peeps with nonsence likes some peeps do (you know the kind, having 600x450 signature picture crap, and usually write just 1 word.
).
Anywho, I doubt the original cartridge would/could? be corrupted by just reading it, and when you know something is "as-is" with such implicit "stuff could happen, *scary voice* beware!!" One wouldn't make a backup before trying to put it on the cart.
I've no idea what kind of routines she's using though and how they might corrupt things. As she is the first I heard of that could actually make a backup and/or restore without rewire-ing, I wonder what all the "beware" is about. Imo, a simple check could see if the data was corrupted (while, for the backup from org cart anyway ... restoring is rather difficult to check if it's only 50% ... 10x to be "sure"?).
Meh, I think she'll "crack the case" someday. For the moment I'd be sattisfied for being able to load my USA save to an original EUR cart (prob buying saturday and get a Arcues from "toysxl" if it doesn't mind US carts (prices are so high here, I usually import ... WAY earlier and a lot cheaper).
If not, I'll just download the ticket and info.
At least my "enemy" is called Silver now ... I kinda wonder why my legit pokemon (captured and raised myself) sometimes have yellow/orange or red IV's though. Guess I'll have to dig into all that IV/EV some more.
