In their own words
ESPectrum
ESPectrum is free, GPL-3.0 emulator firmware for Sinclair ZX Spectrum computers on Espressif ESP32 boards. It emulates Spectrum 48K, 128K, +2A, and Pentagon 128K systems, plus Microdigital TK90X and TK95 models. Supported boards include Lilygo TTGo VGA32 and Olimex ESP32-SBC-FabGL. Video output offers standard VGA, machine-rate VGA, and 15 kHz CRT modes in 16:9 or 4:3. Emulation includes the Z80, AY-3-8912 sound, beeper and microphone behavior, contended memory, and floating-bus effects. Users can connect PS/2 keyboards, joysticks, DB9 joysticks through a converter, and a PS/2 mouse acting as a Kempston mouse. It reads TAP, TZX, SNA, Z80, SP, TRD, and SCL files. Installation uses an online web flasher or release binaries. A FAT16- or FAT32-formatted micro SD card stores programs, disks, snapshots, and captures. PlatformIO builds are described for Windows, GNU/Linux, and MacOS/X.
