ES-DE Frontend vs KNULLI

ES-DE Frontend browses and launches games from a multi-platform collection and can also run locally installed games and applications. It supports more than 150 game systems and comes configured for a large selection of emulators, game engines, game managers, and gaming services. Its built-in scraper downloads game details and media, including images, videos, and manuals. Users can adjust configuration options and themes, and download additional themes through the built-in theme downloader. The interface supports full controller navigation. Windows, macOS, and Linux editions are free to download and use, fully open source, and may be distributed freely. The Android release is a paid, partially closed-source app, and no price is listed. It is available through Patreon, Samsung Galaxy Store, and Huawei AppGallery. The Android FAQ gives 64-bit Android 10 or later as the basic requirement and says one purchase can be used on all of the buyer’s devices without a subscription or additional costs. Support links include a user guide, FAQs, and Discord.

KNULLI is free, open-source custom firmware for supported retro-gaming devices, including handhelds and bartops. It runs on Linux and self-hosted setups, with supported platforms including Anbernic RG series, GoRetroid Pocket 5 and Mini, Miyoo Flip, Powkiddy RGB30 and X55, Orange Pi Zero 2w, and TrimUI Brick and Smart Pro. The system provides EmulationStation or Simplemenu/Simplermenu+ frontends, RetroArch, and multiple libretro cores. It adds RetroAchievements, netplay, cover art, and thumbnail scraping through ScreenScraper, TheGamesDB, and ArcadeDB. Wireless and Bluetooth features depend on the device, while external USB wireless adapters are supported. Syncthing synchronizes saves between KNULLI devices or backs them up to a NAS, not a cloud. Installation requires a device-specific image flashed to an SD card or internal storage. Games, BIOS files, saves, and themes must use a strict case-sensitive folder structure.
