What Amiga 500 ESP32 is

Amiga 500 ESP32 is an educational emulator project for ESP32-S3 hardware, with a Linux/WSL PC build for development. It boots Kickstart 1.3 and loads Workbench 1.3 from an emulated ADF disk. The OCS chipset implementation includes Agnus, Denise, Paula, sprites, copper, blitter, and dual CIA components. The README reports about 31 fps on the Workbench desktop with sprites and audio active. The reference build requires an ESP32-S3 N16R8 with 16MB flash and 8MB OPI PSRAM, an ST7796 display, and a MAX98357A I2S amplifier. Cabinet joystick and buttons map to joystick and mouse inputs. The PC build can render PPM or BMP, write WAV audio, accept scripted input, and run regression tests. Setup uses Arduino IDE, ESP32 core 2.x, and Python 3 to embed user-supplied ROM and disk images. ROMs, Workbench, and games are not included.

Good

  • Runs on ESP32-S3 hardware
  • Emulates major Amiga OCS components
  • Includes a Linux/WSL development build
  • Supports scripted input and regression tests
  • Uses standard ADF AmigaDOS loading

Watch out

  • No keyboard emulation
  • OCS only, without AGA or fast-RAM autoconfiguration
  • Audio may underrun in heavy scenes
  • ROMs and games are not included

Who it suits

It suits makers and learners building an Amiga 500-style ESP32 project or developing the emulator on Linux/WSL. Users must supply legally obtained ROM and disk images.

Verdict

This project combines a physical ESP32-S3 build with useful PC development tools and core Amiga 500 emulation. Its hardware requirements and missing keyboard, AGA, and included software limit it to specific educational or maker setups.

The facts

Hardware requirement
The ESP32-S3 build requires an N16R8 board with 8MB OPI PSRAM.checked 8 Oct 2026
Input and audio
The cabinet joystick and buttons map to Amiga joystick and mouse inputs, and Paula audio outputs over I2S.checked 8 Oct 2026
Intended audience
The maker describes it as an educational, non-commercial project.checked 8 Oct 2026
Known limitations
The README lists no keyboard emulation, no AGA or fast-RAM autoconfiguration, and no custom raw-MFM loaders.checked 8 Oct 2026
License
The original emulator code is under the MIT License, which does not cover the Musashi core or Amiga ROMs and commercial software.checked 8 Oct 2026
Limit: audio
Real-time audio can underrun in heavy scenes when the ring buffer starves below about 50 fps.checked 8 Oct 2026
Limit: disk loading
Custom raw-MFM loaders using DSKSYNC/DSKBYTR polling are not implemented; standard AmigaDOS loading works.checked 8 Oct 2026
