PlayStation Portable Emulator

Before you play

This page uses EmulatorJS with the configured ppsspp core. You need your own lawfully obtained game dump; this site does not supply commercial ROMs or BIOS files.

PSP input here is a disc image, not a folder of extracted game files. CSO is a compressed disc-image container.

This app does not require a BIOS selection to enable Start. That is an interface rule, not a guarantee that every game or media type is free of firmware requirements.

The emulator runtime must load before a game can start. Your selected game files are used locally, not uploaded to a game server.

Accepted files

This page accepts: .iso, .cso. These are importer extensions, not a tested game compatibility list.

Select a game file in one of the listed formats. A generic BIN or ROM extension does not identify the correct system.

ZIP containers can be extracted locally by the importer. Keep all required game files together; extraction does not convert a dump into another system or format.

Controller setup

PSP uses a D-pad, one analog nub, four face buttons and two shoulder buttons. Map the analog input separately from the D-pad.

Use the player input settings to inspect or change bindings. Focus the game before using the keyboard, and connect a gamepad before checking its inputs. Browser recognition does not guarantee every controller or accessory works.

Known limits

PSP 3D workloads can be demanding in a browser. A recognized ISO or CSO is not evidence that a game will run correctly or at full speed.

Performance and accuracy depend on the game, core, device and browser. No per-game compatibility or full-speed guarantee is made.

The local library may need you to re-link files when browser storage is unavailable or cleared. Keep original dumps and independent backups of important progress.

If a game does not start

For slow PSP games, try the player settings and close other heavy tabs. Renaming a different file to ISO does not convert it into a disc image.

Check the player error message, the selected system and the original dump first. A successful extension check does not validate the file contents. See Guides for the import workflow and the core reference below for system requirements.
