I'm using the Asia version of the 3DS. I've been playing US games on it and I have no problems. It also has a $ currency on the eshop. It has a firmware version of 7.1.0-15U.
Now, my question is, will a US account prepaid card work on it? I want to buy Pokemon Bank because my trial is nearly over, but the lady on a local store told me that their prepaid card works on US 3DS units.
Some people told me that the US and Asia version are the same and their only difference is the charger (110v for US and 220v for Asia), but I just want to be certain that the US prepaid card will be accepted in my Asia 3DS eshop. So will it work?
