5. Common Issues in Version 1.7.0

  • “BIOS not found” – Incorrect folder path or missing .nvm (NVRAM) file.
  • Region mismatch – Some games require matching BIOS region (e.g., NTSC-U game with NTSC-U BIOS).
  • Corrupt BIOS – Using an incomplete or patched BIOS (e.g., “PS2-170.bin” from untrusted sources) may cause emulator crashes.

Best Practices for Managing Your BIOS in 1.7.0

  1. Backup your BIOS folder to cloud storage or an external drive. A lost BIOS means you cannot run PCSX2.
  2. Do not mix BIOS versions from different consoles in the same folder. It confuses the emulator.
  3. Use the BIOS dump tool included with PCSX2. Since version 1.7.0 build 1230, PCSX2 includes a "BIOS Dumper" utility (Tools → BIOS Dumper) that guides you through extracting BIOS from a real PS2 via USB.

3. Legal Status of BIOS Files

Sony Computer Entertainment holds copyright over the PS2 BIOS.

  • Legal: Dumping BIOS from your own physical PS2 console (using tools like dumpBIOS or uLaunchELF).
  • Illegal: Downloading BIOS files from websites or sharing them, as this violates DMCA and copyright law.

PCSX2’s official documentation explicitly advises users not to download BIOS files and only use personal dumps. PCSX2 1

If I own a PS2, can I share my BIOS with a friend?

No. The BIOS license is tied to your specific console. Sharing it is copyright infringement.

The Legitimate Method: Dump Your Own PS2 BIOS

If you own a physical PlayStation 2 console, you can legally dump its BIOS. Here’s how:

What you need:

  • A compatible PS2 console (fat or slim).
  • A USB flash drive (FAT32 format).
  • A copy of FreeDVDBoot (for slim models) or a modded memory card with uLaunchELF.

Steps:

  1. Download the BIOS Dumper homebrew tool.
  2. Transfer the dumper to your PS2 memory card or burn it to a CD-R.
  3. Run the tool on your PS2. It will extract the BIOS file(s) to your USB drive.
  4. The dump will produce files named bios.bin, rom1.bin, rom2.bin, and erom.bin.
  5. Transfer these files to your PC.

Legal and Ethical FAQ

Is PCSX2 itself legal?

Yes. The emulator is open-source and contains no Sony code.

Why the BIOS is Crucial for PCSX2 1.7.0

Unlike a traditional PC game, a video game console has a built-in operating system called the BIOS (Basic Input/Output System). The BIOS is responsible for:

  • Booting the console.
  • Managing the memory cards.
  • Controlling the DVD/CD reader.
  • Handling controller inputs at the lowest level.

PCSX2 does not emulate the BIOS; it requires an exact copy (dump) of a real PS2’s BIOS. Without it, the emulator cannot function. When users search for "pcsx2 170 bios," they are typically looking for the recommended BIOS version to pair with the 1.7.0 update.
