Video games are similar to computer games or a personal computer games or PC games. A video game is an advanced software program that makes extensive use of rich media. That is a video game, makes use of the latest technology in multi media, graphics to create an interface that makes use of computer animation. The softwares that a video game interface uses are complex, and emulators are one such set of softwares. An Emulator may be a device (or hardware) or a software that emulates or copies the behavior of another software or hardware system. This helps in systems being compatible with each other, and this applies to both hardware systems and software programs. When we refer to 'compatibility' as regards softwares like Operating Systems or hardware like printers, this is what we refer to. Emulators are designed or programmed in such a way that they create emulation tricks that makes a software or hardware device into the understanding that the software or hardware that it is interacting with is a similar software or device. However, there are certain problems to. If the emulator does not have the speed of the original software, then using an emulator may actually slow down a software or a hardware. This means that tasks will be performed more slowly than others. In extreme cases this may lead to the stalling or 'hanging' of a device. These might prove to be major conveniences. Typically most emulators emulate or mimic a pattern of hardware architecture In cases where an operating system or operating software is required, the operating system may be emulated by the emulator too. The emulator will successfully analyze and interpret the Operating System or OS, and the software that it is about to emulate. This feature is very often used by gaming devices. An advanced form of the emulator is called the simulator, and this is extensively used by video games. Emulators are vital devices, and the CPU simulator is considered as a complex aspect of an interpreter. Quite a few emulators are designed in a pattern that will enable them to emulate another device efficiently, these usually come with 'pre packaged' simulators to simulate the CPU (central processing unit of a company). A CPU simulator in its very basic from is termed as an interpreter. An interpreter is designed to perform the execution pattern of a program code that is being emulated. Emulators as far as video games are concerned come in a number of categories. As far as arcade video games are concerned you have the Callus, or the EmuDX Enhanced Arcade Machine Emulator, or the Nebula to name a few. Video game console emulators include Sega Systems, Nintendo Systems, and Atari. Click on the links of the site to know more about Emulators, in the world of Video Games.
