Hacking same file multiple cartridges - Kid Icarus

Hi.

One of my friends is asking me to get his KI save in somebody's else cart. Are they going to have any problem if they try to play online?

are those saves liked to their respective Cart ID?

Yes they're encrypted by the UniqueID.

:o so one cart's save won't work on other cart?

It'll just complain it's corrupt and make it write a blank save
