rememories

playing around with recovering an original playstation memory card.

install

• You'll need to upload the reader.ino file to your Arduino
• You'll also need to install the pyserial library in a Python 3 environment (this is in requirements.txt)

when installed, you can run with: python writer.py /location/of/arduino --file output_filename.mcr
