Systems: Sony PSP (psp) · Runs as: homebrew NRO · Get it: m4xw's standalone port (also announced via Patreon)

Best effort: this guide is community-maintained and may lag behind new releases. The emulator's own site (linked above) is the authoritative source — if anything here doesn't match what you see, trust their instructions.

PPSSPP is the PSP emulator, and m4xw's standalone Switch port is one of the best-running emulators on the console — generally smoother than the PPSSPP core inside RetroArch, which is why the hub page recommends the standalone.

Install

  1. Download the standalone build (a .7z) — the Homebrew App Store listing or m4xw's release posts carry the current link.
  2. Extract to the root of your SD card. The package is a ppsspp folder containing assets plus the launcher; newer builds keep the .nro in the package's own switch subfolder — launch that one, and delete any stale ppsspp.nro sitting directly in sd:/switch/ from an older install so you don't boot outdated assets.
  3. Launch from the homebrew menu. First run creates its memstick data folder (save data, config) alongside the app.

Point it at your HaulNX library

Nothing to configure — PPSSPP has a built-in file browser:

  1. Download PSP games with HaulNX; they land in sd:/roms/psp/.
  2. In PPSSPP: Games tab → browse to /roms/psp (the SD root is /).
  3. PPSSPP remembers the folder and shows your library with box art on the Games screen from then on. New downloads just appear — no rescan ritual.

Format notes

  • PPSSPP reads .iso and .cso directly. It does not read zips — if a game came down as a .zip, extract it in place (HaulNX's file browser under Manage data can delete leftovers afterward).
  • No BIOS files needed — PSP emulation doesn't use one.

Tips

  • Most 2D and lighter 3D games run full speed at 2x resolution; demanding 3D titles may want 1x. The auto frameskip setting is the first thing to reach for.
  • Save states and saves live in the memstick folder next to the app — back that folder up if you reinstall.
  • Docked mode + overclock (via sys-clk or similar) noticeably helps the heavy titles.
