Ultralight/NTAG simulation. Incorrect ACK/NACK format
I'm using Iceman Fork to simulate Ultralight/NTAG (hf mfu sim t 2).
At first, simulator not supports WRITE command (0xA2) to store pages into emulator memory from reader.
At second, simulation of any other commands such as MIFARE_ULEV1_READ_CNT, MIFARE_ULEV1_INCR_CNT, MIFARE_ULEV1_CHECKTEAR sends incorrect ACK/NACK answer to reader using simple EmSendCmd(...) function call. Datasheets (MF0ULX1.pdf, NTAG213_215_216.pdf) defines ACK/NACK as 4-bit commands. In this case for tags of types 2 and 7 method SimulateIso14443aTag(...) must use EmSend4bit(...) function call to answer ACK/NACK.

Good catches, how about add an issue on Github?
