I'm looking for alternative solutions that can be done immediately, if possible without the use of money, but if nothing else works I'll gladly buy a new card.
As of yesterday, whenever wireless communication is enabled, after 10 seconds my 3DS will stop whatever it was doing and pull up the black screen stating:
"An error has occurred. Hold down the POWER Button to turn off the power, then turn it on and try again. For help, visit...
@Xdqwerty, power through a coil of wire causes an electromagnetic field to be generated. Another coil of wire can be set up to harness the power from that electromagnetic field and turn it into usable energy for charging a device
@Xdqwerty, wire is definitely more practical IMO. Hell these days you can charge a laptop over USB, can't charge a laptop wirelessly though. Wireless chargers, even "fast" ones, are only good for slowly charging devices, plus they generate a good amount of heat too
