'''[[PCSX2''' ]] is an open -source, plugin-based [[PlayStation 2]] emulator. Its purpose is to mimic the PS2 hardware using a combination of MIPS CPU [https://en.wikipedia.org/wiki/Interpreter_%28computing%29 interpreters], [https://en.wikipedia.org/wiki/Dynamic_recompilation recompilers] and a [https://en.wikipedia.org/wiki/Virtual_machine virtual machine] which manages hardware states and PS2 system memory.

For those with DualShock 3 controllers, use the new [[SCP Driver Package]].
Either that, or you can use [http://forums.pcsx2.net/Thread-Pokopom-KrossX-s-Pad-Plugin the Pokopom XInput Plugin.] If you use a DualShock controller running under an XInput wrapper such as SCP Server, then this plugin is a no-brainer. It's very customizable, and you don't have to configure it beforehand. All of the buttons are bound at startup.
===Video Setup===
Now, most of the video options are very straight-forward. However, there is one that probably bears explaining: The interlacing modes. Now, many games can run fine without interlacing modes. You can just select "None" and everything will be fine. However, some games, such as Gran Turismo 3 and Dark Cloud, will have a "jitter" effect if you don't have interlacing modes enabled. The "Sawtooth" interlacing method is not recommended at all. Artifacting is far too heavy to be usable. The "Bob" interlacing method has the least artifacts out of all of them, but it can still let some jittering pass through. The "Blend" interlacing method has the least amount of jitter. However, that comes with a pretty hefty side-effect: blurriness. Yes, the Blend interlacer does frame-blending. This is also known, more colloquially, as motion blur. This means that if there is heavy jitter, the video output will be extremely blurry since the two jittering frames will blend together. Only use this interlacing method as a last resort.
==Issues==
===Automatic gamefixesgame fixes===Whenever you encounter any kind of bug that isn't graphical in nature, objects going through other objects, untargetable objects that should be targetable or A.I. freezing for example, make sure that the automatic gamefixes game fixes option from the system menu is activated.
===Major graphical glitches===
If the log warns you one or several time about being out of memory or the emulator crashes without warning several times in a row after playing for around the same amount of time you will need to apply a patch to make the executable large address aware, its more commonly referred to as the [http://www.ntcore.com/files/4gb_patch.zip 4GB patch].
If the log warns you about TLB miss you are either:
*Using a bad dump of a game - , in which case you'll need to [[Ripping Games|re-rip your disc]] or [[Need_Games%3F|re-download the game]] you are trying to play.*Playing the game directly from your DVD drive - , in which case you should [[Ripping Games|rip the game]] and play using the .iso instead (it's not advised to play directly from your DVD drive).*Trying to play a game that isn't supported by the emulator - , in which case you cannot do anything except trying another version of the game (PAL or NTSC-J for example).
If PCSX2 still crashes after doing all of the above, check that you aren't using any speed-hacks and that your system is stable and not overheating especially if you are overclocking.
Black lines are caused by scaling to a non-integer internal resolution (anything other than Yx Native), texture filtering (turn off or to half at most), improperly offset textures (TC Offset, Wild Arms Offset hacks), or improperly handled texture edges (Sprite hack). Native resolution for the most part fixes these issues, however software rendering may be required as well.
==Special Hardwarehardware=====Pressure Sensitive Buttons-sensitive buttons===The DualShock 2 joypad which comes bundled with the PS2 has all buttons and sticks with variable pressure states.
While most PS2 games don't require this feature (, instead preferring variable trigger / stick pressure, like in Chulip where to get (e.g. sneaking past a the sleeping dog you need to move the left stick more slowlyin Chulip), a select few do. Some examplesinclude: * All three attack buttons in the Bouncer do different attacks based on whether the press was light, medium or strong. Same goes for the musical game Mad Maestro. * Star Ocean 3 has a musical item that plays different melodies depending on pressure and they're required for progressing. * Metal Gear Solid 2 also needs pressure sensitive buttons to get past some sections.
Games requiring variable trigger pressure need physical controllers with analog sticks, but rare are third-party controllers which support variable pressure buttons. To know if your controller supports it, open the LilyPad plugin settings by going to the PCSX2 menu and selecting "Config", "Controllers (PAD)", and "Plugin Settings". At the LilyPad plugin popup, select your gamepad from the list of detected controllers in the "Device Diagnostics" box in the lower left then click the "Test Device" button.
An additional button needs to be mapped to circle as well but configured to deliver "light" pressure. This is done by opening the gamepad plugin configuration and choosing a rarely used key - for example the lower shoulder button L2 - and remapping it to the circle button, and setting the sensitivity to 0.500 or thereabouts. In the game, merely use the remapped L2@circle button to deliver "light" tap/hold tunes while the regular circle button can be used normally to deliver "hard" tap/hold tunes.
