While you should get the BIOS from your own PS2 (otherwise it is illegal from what I remember about emulator laws), if you want to play a game that has been region-locked for your PS2 you will need to download the correct BIOS online, if your too lazy to dump it from your PS2 you can get all the BIOS for all regions here.
PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. Its purpose is to emulate the PS2’s hardware, using a combination of MIPS CPU Interpreters, Recompilers and a Virtual Machine which manages hardware states and PS2 system memory. This allows you to play PS2 games on your PC, with many additional features and benefits.
These BIOS files cover all PlayStation 2 models and all regions (including Japan edition, Europe edition, USA edition, and China, HK edition), and they are enough to meet the needs of any PS2 emulator players. I dare say this PS2 BIOS files AiO package made by AppNee is the most comprehensive one available on the whole Internet, and all of which were tested on PCSX2 emulator, working all right!
Notes:
Also, You need the Visual C++ 2015 x86 Redistributables for this version to work.
PCSX2 1.4.0 is the last version to support Windows XP. So Windows XP is no longer getting updates (including security-related updates), and graphics drivers for Windows XP are older and no longer maintained.
Make sure to update your operating system, drivers, and DirectX (if applicable) to ensure you have the best experience possible. Also, Having a newer GPU is also recommended so you have the latest supported drivers.
Because of copyright issues, and the complexity of trying to work around it, you need a BIOS dump extracted from a legitimately-owned PS2 console to use the emulator.
PCSX2 mainly takes advantage of 2 CPU cores. As of this commit, PCSX2 can now take advantage of more than 2 cores using the MTVU speed hack. Also, This can be a significant speedup on CPUs with 3+ cores, however, on GS-limited games (or on CPUs with fewer than 2 cores) it may be a slowdown.
System Requirements:
Minimum
OS: Windows Vista SP2 or newer or GNU/Linux (32-bit or 64-bit)
CPU: Any that supports SSE2 (Pentium 4 and up, Athlon64 and up)
GPU: DirectX 10 GPU or better
RAM: 2GB or more
Recommended
OS: Windows 7/8/8.1/10 (64-bit) or GNU/Linux (64-bit)
CPU: Intel Haswell (or AMD equivalent) @ 3.2GHz or better
GPU: DirectX 11 GPU or greater
RAM: 4GB or more
Use Instructions:
So Download and extract the package
Also, Placing the BIOS files in the same folder with your PS2 game ROMs is a good idea. Of course, each kind of emulator is different, just ensure to check their ‘readme’ file for specific instructions
So Open your PS2 emulator and specify the BIOS files location if required
Done, enjoy!

The PCSX2 project has been running for more than ten years. Past versions could only run a few public domain game demos, but newer versions can run many games at full speed, including popular titles such as Final Fantasy X and Devil May Cry 3. Visit the PCSX2 homepage to check the latest compatibility status of games (with more than 2000 titles tested), or ask for help in the official forums.
The latest officially released stable version is version 1.4.0.
Installers and binaries for both Windows and Linux are available from our website.
Development builds are also available from our website.
Minimum
OS: Windows Vista SP2 or newer or GNU/Linux (32-bit or 64-bit)
CPU: Any that supports SSE2 (Pentium 4 and up, Athlon64 and up) @ 1600 STR or better

RAM: 2GB or more

You need the Visual C++ 2015 x86 Redistributables for this version to work. Note: Visual C++ 2017 is directly compatible with Visual C++ 2015. While the project is built with Visual C++ 2015, either version will work.
PCSX2 1.4.0 is the last stable version to support Windows XP and Direct3D9. Windows XP is no longer getting updates (including security-related updates), and graphics drivers for Windows XP are older and no longer maintained.

Requirements benchmarks are based on a statistic from the Passmark CPU bench marking software. When we say 'STR', we are referring to Passmark's 'Single Thread Rating' statistic. You can look up your CPU on https://cpubenchmark.net to see how it compares to PCSX2's requirements.
