Amiibosettings_byte0 bit5 must be set, and the byteswapped amiibo_appID in amiibosettings must match the input appID. Once all the checks pass, the state field checked by the [[NFC:ReadAppData|reading]]/[[NFC:WriteAppData|writing]] commands is set to 1. This command does not check if the appdata is already opened(state field set here being already set).<br /> <br /> Error 0xC8A17638 is returned for amiibo_appID mismatch.</div>
