Show HN: Pokémon Emerald Ported to Raspberry Pi Pico 2
A developer has successfully ported the game Pokémon Emerald to run natively on a Raspberry Pi Pico 2 microcontroller. The project achieves 60 frames per second by recompiling the game code and reimplementing video hardware in software.
Why it matters
It demonstrates the impressive capabilities of low-cost, modern microcontrollers for retro-gaming and embedded systems engineering.
Pokémon Emerald running natively on a $6 microcontroller — full game, 60 fps, HDMI out, real buttons, saves that survive a power cycle. No emulator: the pret decompilation is recompiled from ARMv4T to Cortex-M33 and the Game Boy Advance's video hardware is reimplemented in software on the second core.
Target board is a WeAct Studio Core2350B (RP2350B, 16 MB QSPI flash). The whole game — code, graphics, maps, music — is an 11.7 MB image executed in place from flash.
