Hello World Core
Source: examples/hello-libretro
The hello example is the first smoke-test core. It demonstrates:
- a
cdylibpackage, Coreplusexport_core!,- no-game startup,
- fixed 320x240 / 60 FPS / 48 kHz AV info,
- a solid blue default-format software frame,
- silent stereo audio.
The source intentionally stays tiny. For the reusable minimal lifecycle, use
examples/software-libretro, which keeps frame/audio buffers
in core state and applies its content contract consistently to metadata and the
environment.
