Show HN: Pokémon Emerald Ported to Raspberry Pi Pico 2
TL;DR
Pokémon Emerald has been successfully ported to the Raspberry Pi Pico 2, running natively at 60 fps with full game functionality. This implementation uses a custom software re-creation of the Game Boy Advance's video hardware.

Key Takeaways
- Explore using Raspberry Pi Pico for retro game projects.
- Utilize software reimplementation techniques for hardware adaptation.
- Investigate the limitations of audio and link cable functionality.
- Review the engineering log for insights on porting challenges.
How It Works
The port leverages a software rasterizer for the GBA's video processing unit (PPU), allowing the game to run efficiently on the Pico 2's dual-core architecture. Game logic is handled on one core while the second core manages rendering, achieving a frame rate of 60 fps.
The memory map of the GBA is preserved, enabling the game to interact with memory in a familiar way, while the display output is managed through a direct memory access (DMA) control block, ensuring smooth video output without CPU intervention.
⚠ The Catch
Audio support is incomplete, with certain sound features not yet implemented, and the link cable functionality for multiplayer and trading is absent.
