- Setup targets Arduino IDE and dedicated hardware
- The project is experimental and under development

Our verdict on ESP32-FabGL-SMSEmulator

ESP32-FabGL-SMSEmulator is an experimental Sega Mark III/Master System emulator built for ESP32 hardware. It is aimed at developers and hardware-project builders who want to assemble a dedicated console-style setup rather than install an emulator on a general-purpose computer. The project uses the FabGL library and supports VGA video output, PS/2 keyboard input, and external Atari-specification controllers connected through serial UART. Its published target is approximately 30 FPS, making it a focused implementation for a specific board and console family.

The feature set centers on practical hardware integration. SD-card SRAM save and restore provides three slots, while configurable frame-skip timing gives builders control over performance behavior. The project also includes pseudo-SCC sound mode and an option to remove the original sprite limit. Together, these settings give the emulator more configuration depth than a minimal display-only port. Controller support is especially tailored to custom builds: input can come from a PS/2 keyboard or external Atari-specification controllers over serial UART. Builders should plan around the ESP32 Dev Module, Arduino IDE, VGA output, and required PSRAM when designing the system.

This is a narrow project rather than a broad emulator package. Its supported platform is ESP32, and its scope is Sega Mark III/Master System emulation, so it suits people who value a specific hardware target and configurable low-level behavior. The project is currently under development, which matters for anyone seeking a finished, broadly supported application. Choose it for an ESP32-based console or embedded display project with physical controls, SD-card saves, and adjustable emulation options. Choose another emulator if you need wider platform support, a general desktop installation, or a more mature project.
