SVI-328 PicoROM is a ROM emulator for Spectravideo 328 which uses a Raspberry Pico 2 W microcontroller board to emulate a SVI-328 game ROM cartridge.
Designed to integrate into the conventional cartridge slot of the SVI-328, this cartridge allows wireless transmission of ROM games from macOS/PC to the SVI-328 via Wi-Fi without any hardware modifications.
