pylibretro

⚠️ This library is currently in a severe pre-alpha state. At the moment it is however able to load the 2048 core, press buttons and get screen output (as you can see below!). However, many callbacks and functions aren't handled, other cores may segfault etc. Use at your peril.

Installation

pip install pylibretro

You can install the dependencies for the examples in examples or the snippet below by running pip install pylibretro[examples]

Usage

You can create the GIF shown above by using the example file in this repository. However, here's a condensed, minimal usage example:

from pylibretro import Core, buttons
import platform

from PIL import Image

lastframe = None

def on_frame(frame):
    global lastframe
    lastframe = frame

# Load the core
if platform.system() == "Linux":
    core = Core("./2048_libretro.so")
elif platform.system() == "Windows":
    core = Core("2048_libretro.dll")

core.on_video_refresh = on_frame
core.init()
core.load_game(None)

# Start a 2048 game (by pressing the START button for one frame)
core.joystick[buttons.START] = True
core.run()
core.joystick[buttons.START] = False

# Run core for 10 frames
for i in range(10):
    core.run()

# Show the last screen output
lastframe = Image.fromarray(lastframe)
lastframe.show()
