Version 12 introduced stricter DVD region key checks. When you dump a BIOS from a console, you also need to dump the "DVD Player" ROM (usually ROM1 , ROM2 , and EROM files).

Some demanding games (e.g., Metal Gear Solid 2: Substance , Ratchet & Deadlocked ) require precise IOP timing. The v12 BIOS tightens IOP interrupt response times. If your emulator uses the "Interpreter" instead of the "Recompiler" for the IOP, the game will run at 5 FPS. If it uses the Recompiler incorrectly, the game will hang during FMV sequences. A "working" v12 BIOS requires the emulator to be set to with EE Timing Hacks enabled.
