* Recompilers for Emotion Engine (EE), Vector Unit 0 (VU0) and Vector Unit 1 (VU1). They are used to translate some parts of PS2 original machine code into x86 machine code, making the executing of it many times faster than the usual emulation. Due to the fact that PS2 machine code is absolutely different in almost every way possible from x86 these recompilers are probably the most complicated parts in PCSX2. | * Recompilers for Emotion Engine (EE), Vector Unit 0 (VU0) and Vector Unit 1 (VU1).

* Patch system helps to create cheats for any game easily so you won't be frustrated when you cannot progress because of the extremely hard game boss. Also it can be used to patch code skipping some parts where emulation is still broken (which ultimately can make the game playable).

Harware requirements are very game-dependant although it mush be noted that the bottleneck of this emulator in most cases is CPU rather than GPU (video card). So the faster CPU you'll get the better PCSX2 will work for you. Some games however can be slowed down because of unoptimized GFX code or even because of your weak GPU card (for example [[Final Fantasy XII]] is said to use your GPU in full its | Harware requirements are very game-dependant although it mush be noted that the bottleneck of this emulator in most cases is CPU rather than GPU (video card). So the faster CPU you'll get the better PCSX2 will work for you. Some games however can be slowed down because of unoptimized GFX code or even because of your weak GPU card (for example [[Final Fantasy XII]] is said to use your GPU in full its potential). Intel CPUs are better than AMD ones with PCSX2. Though it doesn't mean in any way that you will be unable to play on AMD CPUs it still says that when in some PC games your AMD and your friend's Intel CPU will perform equally good you may notice that this is not the case for PCSX2. | ||
The frequency of CPUs is not the ultimate meter of their success with PCSX2. The newer optimized CPUs perform better than the old ones using the same frequency. You can easily outperform Intel Pentium CPU with Intel Core CPU because of some optimizations in Intel Cores. However CPU frequency is one of the main factors for smooth PCSX2 use. | The frequency of CPUs is not the ultimate meter of their success with PCSX2.

It could be easier for some to buy PS2 DVD off eBay and start playing in PCSX2. Sadly your original DVD is not everything you'll need to make PCSX2 work. You'll also need the BIOS dumped from your PS2. PS2 BIOS is copyrighted by Sony so getting it from anywhere but your own PS2 is '''illegal''' action like downloading PS2 DVDs from the Internet. So ultimately you'll have to have PS2 to dump your BIOS from it before you will start playing your PS2 DVDs on the PC. One region version of BIOS doesn't make the game from another region unplayable so if you have PAL BIOS on your PS2 you'll be able to play NTSC games and vice versa. | It could be easier for some to buy PS2 DVD off eBay and start playing in PCSX2.
