MAME vs RetroDECK

MAME is a free emulation framework intended to preserve software history by documenting and reproducing the inner components of arcade machines, computers, consoles, calculators, and other electronic amusement systems. It can emulate over 32,000 individual systems from the last five decades. Alongside emulation, it includes an interactive low-level debugger for investigating software behavior, diagnosing emulation issues, and developing software for vintage systems. Its Lua interface can inspect device state, access CPU registers, read and write memory, and draw overlays, though the API may change without notice. Plugins support uses such as external-program communication and alternate interfaces; included examples are Discord Presence and a GDB Stub. MAME can save and load states, record inputs for playback, and capture screenshots or video. It is available for Android, Linux, macOS, and Windows; official Windows binaries require Windows 10 or later. BIOS dumps and copyrighted software are generally not included. The project is distributed under GPL-2.0 overall, while more than 90% of files, including core files, are under BSD-3-Clause.

RetroDECK is a free retro gaming platform for Linux handhelds, desktops, HTPCs and PC consoles. It packages emulators, engines, ports, clients, utilities and the ES-DE frontend in a preconfigured Flatpak environment. The RetroDECK Configurator handles file compression and management, BIOS validation, preset management and component tuning. Steam ROM Manager and ES-DE favorites integration let users add games to a Steam library, while Steam Input layouts support devices such as Steam Deck and external controllers. RetroDECK can connect to RetroAchievements, and PortMaster provides a continuously updated catalog of downloadable ports. Sandboxing isolates the package components. The software supports x86_64 Linux systems, including Steam Deck and Linux desktops. Games, proprietary BIOS files and firmware are not included, so users must provide legally obtained files where required. Save states and cheat support are available. RetroDECK is volunteer-run software; donations are optional and do not provide perks or early access. The plan costs nothing.
