| Symptom | Likely Cause | Solution | |---------|--------------|----------| | "This is not a valid BIOS image." | File is zero-byte or header-corrupt | Find a different source. Compare file size (must be 4,194,304 bytes). | | PS2 startup screen loops forever | BIOS region mismatch with game | Use an NTSC BIOS (39001) for NTSC games. Do not mix PAL/NTSC. | | CDVD plugin crash on boot | Missing erom (DVD player) module | Newer PCSX2 requires a full BIOS dump (usually 4-5 files: .bin, .nvm, .erom). Ensure all are present. | | "BIOS v02.20 not supported" | You downloaded a PS3/PS Classic fake | Redump yourself. The PS2 BIOS cannot be extracted from a PS3. |
