ares vs openMSX

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.

openMSX is a free, open-source emulator for the MSX home computer system, with an aim of 100% accuracy. It emulates almost all MSX, MSX2, MSX2+, and turboR systems, plus some others experimentally. The project lists over 230 machine configurations and over 110 extension hardware configurations. A built-in graphical interface works across supported operating systems. Users can control the emulator with Tcl scripts or a command interface over pipes or a UNIX domain socket, and external applications can connect through that interface. The built-in debugger provides watchpoints, breakpoints, viewers, and real-time data display; save states and a reverse feature support replay or stepping back through time. MIDI connectivity is available through host frameworks on Windows, Mac, and Linux. Downloads include Windows, macOS, Linux, and Android builds, though listed versions differ by platform. Version 20.0 and later requires OpenGL 2 support. Android support is listed only through version 0.15.0, and the default C-BIOS machine does not provide all functionality for a complete MSX machine. Catapult is deprecated; the project recommends its built-in GUI.
