What's a PS2 emulator?

It's a software program that emulates the PS2, thus allowing you to play PS2 games on your PC. Note: You don't need the PS2 game itself to play it on your PC. You just need to download the ROM in order to play the game.

A software emulator allows computer programs to run on a platform (computer architecture and/or operating system) other than the one for which they were originally written. Unlike simulation, which only attempts to reproduce a program's behavior, emulation attempts to model to various degrees the state of the device being emulated. High-level emulation uses a combination of the two approaches in an attempt to retain as much accuracy as possible while having the advantages of simplicity and speed provided by simulation.

A hardware emulator is an emulator which takes the form of a hardware device. Examples include printer emulators inside the ROM of the printer, and FPGA-based emulators.

A popular use of emulators is to mimic the experience of running arcade games or console games on personal computers. Emulating these on modern desktop computers is usually less cumbersome and more reliable than relying on the original machines, which are often old and hard to find, let alone repair. Emulation of arcade and console systems on home PCs usually includes the practice of illegally downloading software from various electronic distribution sources. Nintendo's Wii console gives its users a legal alternative for emulating titles while still allowing them to be played in a console-based environment.

In a theoretical sense, the Church-Turing thesis implies that any operating environment can be emulated within any other. In practice, it can be quite difficult, particularly when the exact behavior of the system to be emulated is not documented and has to be deduced through reverse engineering. It also says nothing about timing constraints; if the emulator does not perform as quickly as the original hardware, the emulated software may run much more slowly than it would have on the original hardware.

Emulation refers to the ability of a program or device to imitate another program or device. Many printers, for example, are designed to emulate Hewlett-Packard LaserJet printers because so much software is written for HP printers. By emulating an HP printer, a printer can work with any software written for a real HP printer. Emulation tricks the software into believing that a device is really some other device.

Its a software that can run PS2 DVDs on PC but you must have Bios to run Emulator

A website that have PS2 emulator

Goodluck

superdork and <º))))><.·´¯`·. are correct. Below is a link to some PS2 emulators--though I don't know any good places to find ROMs (I haven't tried a PS2 emulator, yet).

You can find an emulator for just about every console (even Atari, etc.). I have downloaded emulators and ROMs for NES (JNES), Super Nintendo (ZNES), and N64 (Project 64).

i know where you can get a Nintendo ds emulator and nds roms but ps2? you serious?

Something that runs the source code and helps diagnose bugs in the code.

Or you can put the game in your cd-rom and play it with the emu...i think
