FinalBurn Neo vs openMSX

FinalBurn Neo is a free emulator for arcade games and selected consoles, with builds or ports documented for Android, Linux, macOS and Windows. Its emulation scope includes Capcom CPS-1, CPS-2 and CPS-3, Neo Geo, and Sega System 16. The project is based on FinalBurn and older versions of MAME, and is intended to run vintage games on modern systems. Described capabilities include accurate emulation, high performance, netplay, rewinding and shader effects. The project documents Windows and macOS builds, Linux SDL builds and Raspberry Pi builds; a LibRetro port is also available through RetroArch for many platforms. It recommends SDL2 over SDL1.2, citing a better renderer, on-screen display, game selection and ROM scanning. Linux SDL2 builds can be compiled with make sdl2 and require SDL2, SDL2_image, GCC, make, Perl and NASM. On macOS, the build supports keyboard and mouse input but not joysticks; its launcher imports ZIP and 7z archives. The listed terms allow use, modification and distribution, but prohibit sale or monetary profit; ROM images require legal distribution rights.

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.
