- The `screen` surface is RGB565 instead of RGB888
- `hires` screen mode is not double-buffered, usually resulting in a lower framerate
- `get_metadata` is missing the `author` and `category` fields
- `blit::random` is not a hardware generator
- Multiplayer has no host support
- `blit::random` is `pico_rand`
- Multiplayer has fixed host/device role
- Using the MP3 decoder is probably not a good idea
