Attract-Mode vs Batocera

Attract-Mode is a graphical frontend for command-line emulators such as MAME, MESS, and Nestopia. It is intended for arcade cabinets and control by joystick, gamepad, or spin dial, and runs on Windows, OS X, and Linux, including Raspberry Pi and Odroid. Users can import game lists, generate lists from emulator directories, and set launch commands for individual games. The frontend can retrieve missing game details and artwork from TheGamesDB, Progetto-Snaps, and adb.arcadeitalia.net. Controls can be assigned to joystick, keyboard, or mouse inputs, including combinations. A built-in configuration menu has on-screen help, and settings are stored in text files. Layouts can be scripted in Squirrel and customized with themes, animations, and GLSL shaders. It supports media formats supported by FFmpeg and SWF files through gameswf. The feature list also names Steam support and plug-ins for extensions or integration with external programs. Attract-Mode is free and open source under the GNU General Public License v3. Pause functionality for returning to the frontend and resuming an emulator is listed only for Linux and Windows versions.

Batocera Linux is a free, open-source Linux distribution that turns compatible computers and small devices into retro-gaming consoles. It can run from a USB stick or SD card without changing the computer, or be installed permanently. Download builds are listed for desktop PCs, laptops, Intel-based Apple computers, handheld PCs, Raspberry Pi, Odroid boards, and other devices. Batocera supports many consoles, platforms, emulators, and related applications through a front end based on a modified EmulationStation. Its content downloader provides freely distributed ROMs, bezels, music themes, and other enhancements, with packages handled by pacman. Documentation covers Netplay for supported games and integrations including Kodi, RetroAchievements, The Bezel Project, Syncthing, NAS storage, and a web server. Installation requires at least 16 GB of storage; 32 GB is recommended. Batocera focuses on retro gaming and will not implement emulators for current-generation consoles.
