pylibretro 0.2.0

WIP Python library that runs Libretro cores

pylibretro

⚠️ This library is currently (and probably will remain) 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 (such as the PCSX ReARMed core) segfault etc. Use at your peril.

Installation

pip install pylibretro

(the only dependency is Pillow if you wish to install it manually)

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

lastframe = None

def on_frame(frame):
    global lastframe
    lastframe = frame

# Load the core
core = Core("./2048_libretro.so")
core.on_video_refresh = on_frame
core.retro_init()
core.retro_load_game(None)

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

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

# Show the last screen output
lastframe.show()
