At Last, A Gameboy Advance With Decent Audio

A hobbyist project called GameBoy HiFi Audio replaces the Gameboy Advance's stock PWM audio chip with a custom PCB featuring filtering, EQ, a class D amplifier, an audio codec, and an ESP32 for Bluetooth connectivity. The mod installs on the pads left by the removed original chip and requires no case modification, with full build files available on GitHub.
