I'm trying to find a faster way to get the Golden Mask in Explorers of Sky, and according to Bulbapedia there's a Wonder Mail code for it. But when I enter the code, it says "This password is incorrect. Would you like to try again?". I checked and double-checked that the code was right, but it still won't accept it.
Were Wonder Mail S codes affected by Nintendo's shutting down of previous gen's Interent settings?
Here is the code.
NN00S | 655M=4Q | -+8J0
