What pctation is

pctation is a free PlayStation (PS1/PSX) emulator written in C++17 for Windows and Linux. It is an incomplete project that can run some commercial games; examples shown include Crash Bandicoot, Ridge Racer, Aeon Flux, Deuce, Puzzle Bobble, and Batman Forever: The Arcade Game. Its emulation components include a MIPS I CPU interpreter, a software-rasterized GPU, the Geometry Transform Engine, memory mapping, CD-ROM, a digital controller, timers, and DMA. The interface provides a game-selection screen that scans the data directory for game dumps or executables, a settings dialog, CD-ROM image and PSX-EXE explorers, and FPS and emulation-speed displays. Debugging features include a view of the full GPU video memory and separate windows for TTY output, BIOS calls, RAM, GPU and CPU registers, timers, and drawing commands. Use requires a BIOS and CD-ROM game dumps; optional executables and expansion-slot binaries can be placed in their designated folders. Supported disc-image formats are .iso and .bin. Audio emulation, video playback, 24-bit direct display mode, and cue-sheet parsing remain unimplemented. The project is MIT-licensed. Windows and Linux build instructions are provided, with Linux marked untested.

Who it suits

pctation suits people exploring PS1 emulation or low-level emulator development who can provide a BIOS and game dumps. Its debugger and hardware-focused components may also appeal to users interested in inspecting emulation details.

What it does well

Free and MIT-licensed.
Runs examples of some commercial games.
Debugger includes a full GPU video-memory view.
Supports .iso and .bin disc images.
Includes CD-ROM and PSX-EXE explorers.

What to know first

Audio emulation is unimplemented.
Video playback is unimplemented.
Linux is marked untested.
Requires users to provide a BIOS and game dumps.

Limits

Audio/SPU emulation, video/MDEC playback, 24-bit direct display mode, and cue-sheet parsing are unimplemented. The Linux build is marked untested.

Getting started

Open the pctation GitHub project page.
Use the build instructions for Windows or Linux.
Place a BIOS in data/bios.
Place .iso or .bin game dumps in data/cdrom.
Optionally place executables in data/exe or expansion-slot binaries in data/expansion.
Select a game or executable from the game-selection screen.

Verdict

Choose pctation if you want a free, MIT-licensed PS1 emulator with a detailed debugger and are comfortable with an incomplete project. Look elsewhere if audio or video playback is essential, or if you need a Linux build identified as tested.
