GRport is an unofficial, free fan project. It is not affiliated with, endorsed by or sponsored by Sony Interactive Entertainment. "Gravity Rush", "PlayStation" and "PS4" are trademarks of their owners. GRport contains no game files: you need your own copy of the games, dumped from your own PS4. Please don't ask for game files.

Download

Get the latest release from the Releases page:

• GRport-<version>-windows.zip: everything except FSR 4.
• GRport-<version>-windows-fsr.zip: the same plus FSR 4.

Unzip it anywhere (not inside Program Files), start GRport.exe, choose each game's dumped folder (the one with eboot.bin) and press PLAY. The first PLAY prepares the game for GRport (about a minute). Later versions install from the launcher: CHECK FOR UPDATES (next to LOG) finds them, and your saves and settings stay.
