| Risk Type | Example Consequence |
|-----------|---------------------|
| Malware | Keyloggers hidden in .exe files masquerading as "BIOS patcher." |

Find a genuine NTSC-J BIOS (e.g., SCPH-50000_BIOS_v18_JAP.bin). PCSX2 will run UN5 without patches. The only downside: the PS2 boot screen and system menus will be in Japanese.
