Linux, macOS/ OS X, and Microsoft Windows on x86-based computers are the main development focus of PCSX-Reloaded but various PCSX iterations have been ported to other platforms as well, including Dreamcast, GameCube, PlayStation 3, Wii, Xbox, and various ARM-based platforms (PCSX-Rearmed fork) such as BlackBerry Playbook and Nintendo 3DS. Additionally, PCSX seeks to simulate the functionality of the PlayStation BIOS and consequently does not require a BIOS file dump to operate, making it easier to emulate legally, however Bios emulation is still incomplete so its better to use dumped BIOS to avoid various bugs and reduced compatibility. It also has multi-track cue support and is the only PS1 emulator with compatibility with anti-jitter options in graphics plugins, such as GTE accuracy in the default Peops OpenGL plugin, or Improved coordinate accuracy in Edgbla's gpuBladeSoft and it also supports PeteOpenGL2Tweak plugin. As with many modern emulators PCSX-Reloaded supports savestates and also has Save Rewind feature (currently only OSX and Linux version), Support for ECM files (currently only OS X and Linux version), Support for Libarchive (currently only OSX and Linux version), widescreen hack and makes use of plug-ins to emulate GPU, SPU, and CD-ROM drive functions, a model first established in PSEmu Pro, it uses Peops OpenGL plugin for graphics on default but can also use Pete's OpenGL2, gpuBladeSoft, PCSX2 graphics plugin GSDX, AmiDog GPU plugin, Asmodeans PSXFX shader pack, input plugins such as Lilypad and Pokopom Pad Plugin. PCSX supports network play and external plugins as used by ePSXe. In this context PCSX-Redux shares several approaches with the PlayStation 2 emulation successor project PCSX2 Additionally the plugin system will be replaced through a single monolithic codebase that handles all aspects of the playstation emulation.

Everything should be implemented on top of SDL/ OpenG元+/ ImGui. This fork has the goal of a complete redesign along more up to date code standards. It can be seen as the latest iteration of the original PCSX codebase. In 2019 another fork PCSX-Redux was started. PCSX-df and PCSX-Reloaded coexisted for a while, with PCSX-df merging changes of PCSX-Reloaded back into df. PCSX-Reloaded is a new project created in mid-2009, which is based on the work of the PCSX-df branch, completely independent, and works on bug fixes while maintaining Windows and OS X compatibility alongside Linux. Version 1.10 was released on March 29, 2009. PCSX-df was created in 2006 and added new features, a new GTK-based interface, AMD64 support, and corrected some bugs, but was developed mainly with only Linux compatibility in mind. Official development ceased on September 17, 2003, and development shifted to the new PlayStation 2 emulator, PCSX2.

The emulator was first released for the PC on August 31, 2000.
