* SD lib:

*   N64 - view on controller connector:
*     _____
*    /     \    1: GND        -> Arduino GND
*   | 1 2 3 |   2: DATA       -> Arduino Pin 2
*   |_______|   3: VCC (3.3V) -> Arduino 3.3V
*   (contacts start after about 5mm inside the hole)
*   SD Card:    1: CS         -> Arduino Pin 10
*               2: DI/MOSI    -> Arduino Pin 11
*               3: VSS/GND    -> Arduino GND
*               4: VDD/+3.3V  -> Arduino 3.3V
*               5: SCK/CLK    -> Arduino Pin 13
*               7: DO/MISO    -> Arduino Pin 12
*     Format: use https://github.com/greiman/SdFat/blob/master/examples/SdFormatter/SdFormatter.ino
*
* Can also be used for reading WITHOUT SD Card:
*   1. uncomment "#define ENABLE_SD" below, then compile/upload the code to an Arduino Uno
*   2. $ sudo miniterm.py /dev/ttyACM0 | tee n64-controllerpak-01.log
*        in the menu chose '0' to dump to console
*   3. open .log in text-editor (e.g. kate) and remove all lines except
*        the ones containing the hex dump and store as it .hex - needs to be 1024 lines
*   4. $ xxd -r -p n64-controllerpak-01.hex n64-controllerpak-01.mpk
*   5. $ ls -la n64-controllerpak-01.mpk
*        check size needs to be 32768 and compare the .hex with .mpk using e.g. mc
*        finally inspect it on: https://rawgit.com/bryc/mempak/master/index.html
*
