Ok, so I have an Arduino Mega 2560 and an RFID-RC522. I've wired them together as specified in this image:
Using the equivalent pins 9-13, 3.3v power and GND.

Then I load up AmiiBomb and open up the Amiibombuino Flasher and get this once I've flashed:
Which should mean everything is all good, but when I go to flash an Amiibo...
No matter if I use one of the NTAG215 stickers, the card that came with the board, or the keyfob that came with the board, or even a spare Lego Dimensions tag I have laying around, I get no response from the board.
I've checked all connections, the power light on the RC522 is lit, and everything should be working. But it's not.
Any help would be greatly appreciated.
