If the log warns you one or several times 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].

'''PCSX2''' is an open-source, plugin-based [[PlayStation 2 emulators|PlayStation 2 emulator]]. Its purpose is to mimic the PS2 hardware using a combination of MIPS CPU [[wikipedia:Interpreter_%28computing%29|interpreters]], [[wikipedia:Dynamic_recompilation|recompilers]] and a [[wikipedia:Virtual_machine|virtual machine]] which manages hardware states and PS2 system memory. In 2016, preliminary work was started on [[PlayStation emulators|PS1]] support.<ref>https://github.com/PCSX2/pcsx2/pull/1571</ref>.

The stable builds for Mac and Linux are severely outdated, less so for Windows. Either way, it's still recommended to use the dev builds, unless the latest one is actually broken (which it usually isn't).
==System requirements==
==Overview==
Code for 64-bit support for all major PC versions of PCSX2 including Windows, Linux and macOS was in development from [https://github.com/PCSX2/pcsx2/pull/3451 June 07, 2020]; and both 32-bit & 64-bit builds for all three desktop PC systems started being available on [https://github.com/PCSX2/pcsx2/pull/3451#issuecomment-653720205 July 04, 2020].<ref name="Reddit_1">{{cite web|url=https://www.reddit.com/r/emulation/comments/hkzzv2/pcsx2_now_has_a_64_bit_version/ |title=PCSX2 now has a 64 bit version |publisher=Reddit|accessdate=2020-07-06|date=2020 Jul 04}}</ref> Eventually, this has the potential to reduce the so-called 'technical debt' (Consisting of hacks built in for some games) that still cause issues in 32-bit builds; and broaden the emulator's support for more platforms and devices such as support for ARM64 chips (Also for Mac too).
PCSX2 is a plugin-based emulator in name only. All plugins are developed in tandem with the emulator in the same source tree. With the exception of some specialized input plugins discussed below, there has not been a reason to add additional plugins such as the older ZeroGS/ZeroSPU2 for many years. Similar to current versions of Dolphin, the PCSX2 developers intend to eventually have all the plugins statically linked/"baked-in". To facilitate this, PSX emulator support was dropped from LilyPad and GSdx (does not affect playing PSX games in PCSX2). Currently, all plugins except the graphics plugin (GSdx) have been integrated into the core.
==Issues==
{{main|https://forums.pcsx2.net/Thread-Sticky-PCSX2-General-Troubleshooting-FAQ PCSX2 General Troubleshooting FAQ}}
===Automatic game 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 game fixes option from the system menu is activated.
Crashes could be the results of several things.
Switching between hardware and software rendering rapidly is likely to cause the emulator to lock up. This can be easily avoided by waiting a few seconds after switching between hardware and software rendering before switching again.
If your GPU drivers also crash simultaneously (or you get massive graphical corruption on your desktop and/or a BSOD while trying to run a game) this means you're either using outdated drivers or you're trying to use an AMD card with the OGL renderer and Blending Accuracy set to none, in which case either set it to basic or higher or use the DX11 renderer instead.
If the log warns you about TLB miss you are either:
* 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).
* Trying to play a game with a massive or in some cases any EE overclock applied, in which case turn it back down the speedhack menu.
* Try You need to configure modo clamping check the Wiki to Completo, see if the game requires any specific settings regarding the Clamping Mode of the EE/VU.* Cheats used in the emulator settingsgame's .pnach file are invalid.
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.
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.
==Lightgun Supportsupport==
Lightgun support is available in the pcxs2 emulator via a third party plugin called nuvee. His allows you to use and mouse or mouse compatible device (such as a lightgun) to play the large ps2 library of lightgun games<ref>https://lightgungamer.com/pcsx2</ref>.
