The PSX Serial Dumper Method

  1. Solder three wires to the PS1 mainboard: TX, RX, and GND on the serial expansion header (yes, the 90001 removed the parallel port but kept a 4-pin serial header near the AV port).
  2. Connect to a USB-to-TTL adapter.
  3. Boot the PS1 while holding a specific button combination (varies by firmware) to enter "BIOS dump mode" – a hidden backdoor in v18 that Sony engineers left for factory testing.
  4. Send the dump command (0x44 0x55 0x4D 0x50) over serial.
  5. The console streams 0x80000 bytes (512KB) – that’s your rom0 file.
