Connor McLaughlin 0171dc4241 CPU/Recompiler: Prevent vixl from using scratch registers 
This took too long to find that it was trashing one of our register
cache values. Let it abort instead, until we use the base assembler
instead of the macro assembler.

DuckStation - PlayStation (PSX) Emulator

Main Window Screenshot

Features

  • CPU Recompiler/JIT (x86-64 and AArch64)
  • Hardware (D3D11 and OpenGL) and software rendering
  • Upscaling and true colour (24-bit) in hardware renderers
  • "Fast boot" for skipping BIOS splash/intro
  • Save state support
  • Windows and Linux support - macOS may work, but not actively maintained
  • Currently only .bin/.cue disc image formats are supported. Additional formats are planned
  • Direct booting of homebrew executables

System Requirements

  • A CPU faster than a potato.
  • For the hardware renderers, a GPU capable of OpenGL 3.0/OpenGL ES 3.0/Direct3D 11 Feature Level 10.0 and above. So, basically anything made in the last 10 years or so.
  • SDL-compatible game controller (e.g. XB360/XBOne)

Building

Clone the respository with submodules (git clone --recursive or git clone and git submodule update --init).

Windows

Requirements:

  • Visual Studio 2019
  1. Open the Visual Studio solution duckstation.sln in the root, or "Open Folder" for cmake build.
  2. Build, binaries are located in bin/x64.
  3. Copy the DLL files from dep/msvc/bin64 to the binary directory.
  4. Run duckstation-x64-Release.exe or whichever config you used.

Linux

Requirements:

  • CMake
  • SDL2
  1. Create a build directory, either in-tree or elsewhere.
  2. Run cmake to configure the build system. Assuming a build subdirectory of build-release, cd build-release && cmake -DCMAKE_BUILD_TYPE=Release -GNinja ...
  3. Compile the source code. For the example above, run ninja.
  4. Run the binary, located in the build directory under src/duckstation/duckstation.

Android

Requirements:

  • Android Studio with the NDK and CMake installed
  1. Open the project in the android directory.
  2. Select Build -> Build Bundle(s) / APKs(s) -> Build APK(s).
  3. Install APK on device, or use Run menu for attached device.

Running

  1. Configure the BIOS path in the settings.
  2. Open a disc image file, enjoy.

Default keyboard bindings

Keyboard bindings are currently not customizable. For reference:

  • D-Pad: W/A/S/D or Up/Left/Down/Right
  • Triangle/Square/Circle/Cross: I/J/L/K or Numpad8/Numpad4/Numpad6/Numpad2
  • L1/R1: Q/E
  • L2/L2: 1/3
  • Start: Enter
  • Select: Backspace

Gamepads are automatically detected and supported. Tested with an Xbox One controller. To access the menus with the controller, press the right stick down and use the D-Pad to navigate, A to select.

Useful hotkeys

  • F1-F8: Quick load/save (hold shift to save)
  • F11: Toggle fullscreen
  • Tab: Temporarily disable speed limiter
  • Pause/Break: Pause/resume emulation
  • Space: Frame step
  • End: Toggle software renderer
  • Page Up/Down: Increase/decrease resolution scale in hardware renderers

Tests

  • Passes amidog's CPU and GTE tests in both interpreter and recompiler modes, partial passing of CPX tests
