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.

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]
In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

SeaBIOS is an open-source implementation of an x86 BIOS, serving as a freely available firmware for x86 systems. Aiming for compatibility, it supports standard BIOS features and calling interfaces that are implemented by a typical proprietary x86 BIOS.
The CPU core is a two-way superscalar in-order RISC processor. [3] Based on the MIPS R5900, it implements the MIPS-III instruction set architecture (ISA) and much of MIPS-IV, in addition to a custom instruction set developed by Sony which operated on 128-bit wide groups of either 32-bit, 16-bit, or 8-bit integers in single instruction, multiple data (SIMD) fashion (e.g. four 32-bit integers ...
(Other DOS programs which use protected mode execute using user mode under the emulator.) NTVDM in x86 Windows NT-based operating systems also use VM86 mode, [3] but with very limited direct hardware access. Some boot loaders (e.g. GRUB) use the protected mode, and execute the BIOS interrupt calls in Virtual 8086 mode. [4] [5]
To draw something to the screen, one must send, using 1 of 3 data paths, render commands & assets to the GS via the GIF channel: 64-bit, 150 MHz bus, maximum theoretical bandwidth of 1.2 GB/s. [ 6 ] Display lists generated by CPU/VPU0 and VPU1 are sent to the GIF, which prioritizes them before dispatching them to the Graphics Synthesizer for ...
Project64 is a free and open-source Nintendo 64 emulator written in the programming languages C and C++ for Microsoft Windows. [3] This software uses a plug-in system allowing third-party groups to use their own plug-ins to implement specific components.
