PlayStation ROMs

DuckStation is the current recommendation. It is accurate, fast, handles the library almost completely, and includes modern features like texture filtering, widescreen hacks and per-game settings. Beetle PSX through RetroArch is the alternative for accuracy purists.

ePSXe remains well known but is no longer the best choice; it depends on a plugin architecture that DuckStation has made unnecessary.

DuckStation requires a PlayStation BIOS image to run, and it is region-specific — a Japanese BIOS for Japanese discs, and so on. This must be dumped from a console you own.

Unlike the PS2, some emulators offer high-level BIOS replacements, but compatibility suffers. Using a real BIOS dump is strongly preferred.

PlayStation hardware had no sub-pixel precision, so polygons visibly jitter as they move — a distinctive artefact of the era. DuckStation's PGXP option reconstructs the missing precision and largely eliminates it.

Whether to enable it is taste. Some people consider the wobble part of the look; others find it unwatchable on a large screen.
