ares vs Flycast

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.

Flycast is a free emulator for Sega Dreamcast, Naomi, Naomi 2, and Atomiswave, derived from reicast. It runs on Android, Linux, macOS, and Windows, with releases available as stable tagged versions, master builds, and experimental nightly builds. Android users are directed to Google Play; Linux instructions cover Flatpak and Flathub, while macOS instructions use Homebrew. Windows documentation provides a bootstrap script for building from source. Xbox One and Series users can install a build through Xbox Device Portal. Flycast supports online play, with release notes describing modem-emulation improvements and fixes for online features in several games. Its DCNet service is a free dedicated VPN for Dreamcast games; 30 game servers were available when it was released. Physical Dreamcast controllers work with DreamConn+ and DreamPicoPort adapters. On Android, Google Auto Backup can back up VMU saves and non-volatile memory. The project lists GPL-2.0 as its license and says iOS support has been dropped.
