ares vs XRoar

ares is a free, open-source emulator for multiple systems, with a stated focus on accuracy and preservation. It supports systems including Arcade, Atari 2600, WonderSwan, ColecoVision, NES, SNES, Nintendo 64, and PlayStation, though some listed systems are experimental. Playback options include save states, run-ahead, rewind, and fast-forward. Pixel shaders and optional color correction can alter display characteristics, while Virtual Game-Pads let users configure controls for use across emulated systems. The interface framework uses WinAPI on Windows, Cocoa on macOS, and GTK2 or GTK3 on POSIX platforms. Simple debugging features such as trace logging support development of original software for supported systems. Windows builds support Windows 7 or later; AMD64 binaries require at least Intel Nehalem or AMD Jaguar architecture. macOS binaries require Catalina 10.15 and support Intel and Apple Silicon. The project prefers Linux users compile from source and points to third-party packages rather than official Linux binaries. Source code uses the ISC license. Android is not supported, and a BIOS is required.

XRoar is a free emulator for Dragon, Tandy Colour Computer, Tandy MC-10, and related 8-bit systems. Supported machines include Dragon 32/64/200-E, Tandy CoCo 1/2/3, MC-10, and Matra & Hachette Alice 4K. It runs on Android, Linux, macOS, and Windows, with XRoar Online available in a browser. The emulator reads and writes cassette, floppy disk, and block-device images, and supports machine snapshots. Emulated hardware includes floppy controllers, sound cartridges, Glenside IDE, and several RAM expansions. Video options include PAL or NTSC emulation and composite video simulation, with multiple sound drivers. A GDB remote target supports interactive debugging, though 6803 debugging is not implemented. The Becker port can communicate with pyDriveWire or Drivewire 4. In the browser version, users can fetch cassette, floppy, and hard disk images from the web or upload local files, but its sandbox keeps accessed files temporarily in memory rather than working transparently with local files. Firmware ROM images are required for useful emulation, and floppy write-back is enabled by default. XRoar is GPL version 3 or later software and comes without warranty.
