RetroArch is a free and open-source, cross-platform frontend for emulators, game engines, video games, media players and other applications. It is the reference implementation of the libretro API , [ 2 ] [ 3 ] designed to be fast, lightweight, portable and without dependencies. [ 4 ]
The emulator subsequently uses the BIOS dump to mimic the hardware while the ROM dump (with any patches) is used to replicate the game software. [7] ROM files and ISO files are created by either specialized tools for game cartridges, or regular optical drives reading the data. [16]
PCSX is a free and open-source, video game console emulator that allows software designed to be used with the Sony PlayStation to run on personal computers. Over the years, development changed hands several times with PCSX-Reloaded (PCSXR) now being the main version. As of 2021, the emulator seems to be no longer under active development. [5]
PCSX2 is a free and open-source emulator of the PlayStation 2 for x86 computers. It supports most PlayStation 2 video games with a high level of compatibility and functionality, and also supports a number of improvements over gameplay on a traditional PlayStation 2, such as the ability to use higher resolutions than native, anti-aliasing and texture filtering.

An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
Video BIOS is the BIOS of a graphics card in a (usually IBM PC-derived) computer. It initializes the graphics card at the computer's boot time. It also implements INT 10h interrupt and VESA BIOS Extensions (VBE) [ 1 ] [ 2 ] for basic text and videomode output before a specific video driver is loaded.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
Mednafen (My Emulator Doesn't Need A Frickin' Excellent Name), formerly known as Nintencer, is an OpenGL and SDL multi-system free software wrapper that bundles various original and third-party emulation cores into a single package, and is driven by command-line input. [2] [3] It is distributed under the terms of the GPL-2.0-or-later license. [4]
