The record

Product: An emulator for the SEGA MarkIII / Master System built for ESP32 using the FabGL library; the project is marked as a work in progress.
Video and input: It supports VGA output, PS/2 keyboards, and external controllers connected over serial.
Frame rate: The README reports 60 FPS (59.94 Hz), with every frame rendered.
Audio limitation: FM sound, especially rhythm sections, and some PSG sampling playback have reduced fidelity due to FabGL sampling-rate constraints.
Build requirements: The recommended setup uses an ESP32 Dev Module, FabGL v1.0.9, and enabled PSRAM; PSRAM is required.
Save states: SRAM-compatible titles can save and restore data on an SD card using three slots, and the SAVE folder must be created manually before launch.
External controllers: It accepts Atari-specification D-Sub 9-pin controller signals via UART using RS-232C at 115200 bps on IO39, for two joystick ports.
Controller converter: The README says the Atari-to-serial joystick converter hardware and firmware published in the maker's MSX1 emulator repository can be reused.
Keyboard mapping: The README says users may need to modify source code to adapt key mappings to their keyboard layout.
Development status and support: The developer says most main source code is based on AI-generated code and that they cannot answer detailed questions about its internal logic or specifications.
Licensing: The README directs users to review source-file header comments for license details and says included cores follow the stated FabGL, fMSX, and MIT or free-license policies.
Use disclaimer: The README states that use is at the user's own risk and disclaims liability for resulting damages.
Download availability: The GitHub repository page showed no releases.
