nanoarch.py

A minimal working example of using a libretro core in Python based on nanoarch.c.

How to run

(tested on windows, linux would require slight changes - .dll -> .so etc)

Install requirements from requirements.txt (pip install -r requirements.txt)

Fetch sameboy_librertro core from https://buildbot.libretro.com/nightly/windows/x86_64/latest/sameboy_libretro.dll.zip and extract it inside the same directory as main.py

Run main.py

Whats working

• initializing libretro

• rendering gameboy frames inside SDL2 as a texture

• inputs for gameboy:

  Keyboard	Gameboy
  Left	Dpad Left
  Right	Dpad Right
  Up	Dpad Up
  Down	Dpad Down
  Z	A
  X	B
  ENTER	START
  BACKSPACE	SELECT

• inmemory state serialization (S key) & deserialization (D key).

Whats not working

• Support for cores other than Game Boy due to hardcoded resolution, pixel format & controls (easy to modify - call retro_get_system_av_info and use its information)

• Audio

Leaving it as is to keep code minimal, feel free to implement these in your own projects
