PicoGUS

An ISA sound card emulator, powered by a Raspberry Pi Pico

PicoGUS can emulate Gravis UltraSound, Sound Blaster 2.0 / AdLib (OPL2), CMS/Game Blaster and Tandy 3-Voice, and supports MIDI output with MPU-401 intelligent mode emulation. It comes in two versions: the original ISA card, and the "Femto" edition that can plug into a Hand386/Book8088 or ISA adapter.
