Bringing back my 1998 by building an arduino that can recover a ...
summary
An Arduino using SPI reads an original PlayStation memory card by issuing the card protocol, iterating 1,024 frames of 128‑byte blocks, validating checksums and streaming bytes over USB; soldering to the card or wiring a ripped PlayStation reader provides the physical connection. A Python script assembles the received bytes into a binary memory file which an emulator accepts — the saved Final Fantasy 7 game loads and plays, so the recovery approach actually works.
