The record

Purpose: Retro-Go is firmware for playing retro games on ESP32-based devices.
Officially supported devices: The README names ODROID-GO and MRGC-G32 as officially supported devices.
Emulated systems: Supported systems include NES, SNES, Game Boy, Game Boy Color, Game & Watch, Sega systems, Colecovision, PC Engine, Atari Lynx, and DOOM.
Launcher features: The firmware includes favorites, recently played games, a customizable launcher, cover art, save-state previews, and multiple save slots per game.
Display and speed: Features include scaling and filtering options and turbo speed or fast forward.
File management: A Wi-Fi file manager can be accessed by navigating on a PC to the device's IP address.
Network behavior: After a successful Wi-Fi connection, the launcher synchronizes time through pool.ntp.org, and the README says this cannot currently be disabled.
Licensing: The project is licensed under GPLv2 except for the MSX emulator's custom non-commercial license and the Lynx emulator's zlib license.
Installation: Users can install prebuilt firmware or images from the release page, and the README describes SD-card and USB flashing methods.
Limits: ZIP archives should contain one ROM file, and larger ROMs may fail to load on some devices because ZIP support depends on available memory.
Build requirements: Building requires ESP-IDF, with versions 4.4 through 5.3 listed as supported.
Intended users: The project provides build and porting instructions for people who want to build, modify, or port the firmware to ESP32 devices.
Supported devices: The project officially supports ODROID-GO and MRGC-G32, with other ESP32 devices listed separately.
Networking: The firmware includes a Wi-Fi file manager, and the launcher synchronizes time through pool.ntp.org after connecting to a network.
