This emulator is still in the early stages of development and big games like the tripple A game still don't work, see the compatibility list for more details: https://github.com/red-prig/fpps4-game-compatibility/issues

If your game doesn't work don't create a new issue, check the compatibility list first.

If you want to know the details or just chat, welcome to the discord: https://discord.gg/up9qatpX7M

I am currently rewriting the emulator core in the kern branch and until the work is completed, there will be no support for specific games.

Control layout

To switch to borderless full screen mode, press Alt-Enter.

fpPS4 supports XInput-compatible gamepads natively. You can remap buttons by pressing Esc on the keyboard during emulation. Regardless, you can use a keyboard as a input. A DualShock4 touchpad is emulated by the mouse.
