What pctation is
pctation is a free PlayStation (PS1/PSX) emulator for Windows and Linux, written in C++17. The project is incomplete, but its README gives examples of it running commercial games, including Crash Bandicoot, Ridge Racer and Puzzle Bobble. 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 includes a game-selection screen, settings, CD-ROM image and PSX-EXE explorers, and displays FPS and emulation speed. Debugging tools include a view of GPU video memory and windows for TTY output, BIOS calls, RAM, GPU and CPU registers, timers and drawing commands. Use requires a BIOS and CD-ROM game dumps in designated data folders; executables and expansion-slot binaries can also be added. Audio emulation, video playback, 24-bit direct display mode and cue-sheet parsing are listed as unimplemented. The project uses the MIT license, and Linux is marked as untested in its build instructions.
Good
- Free and licensed under MIT.
- Available for Windows and Linux.
- Includes VRAM viewing and multiple debug windows.
- README lists examples of commercial games running.
Watch out
- Audio emulation is unimplemented.
- Video playback is unimplemented.
- Requires a BIOS and CD-ROM game dumps.
- Linux is marked as untested.
Who it suits
pctation may suit people interested in an incomplete PS1 emulator with debugging tools, or those exploring low-level emulation. It requires a BIOS and CD-ROM game dumps, and Linux setup is marked untested.
Verdict
pctation combines PS1 emulation with a detailed set of debugging views, but several features remain unimplemented. Its incomplete status and untested Linux setup are important considerations before use.
The facts
