DOSBox-X vs FinalBurn Neo

DOSBox-X is a free, open-source DOS emulator for running DOS applications and games on Linux, macOS and Windows. It also supports DOS-based Windows guests, including Windows 3.x and Windows 9x/Me. The project emphasizes general emulation and accurate hardware behavior, with DOS/V services and emulation for NEC PC-98, AX and J-3100 systems. A graphical configuration tool and many virtual-machine options let users adjust the emulated environment. DOSBox-X provides up to 100 save slots, with automatic saving for selected programs or at user-defined intervals. Its emulated NE2000 adapter supports guest networking through PCAP and Slirp backends. Printing can use parallel ports and real or emulated printers, with PostScript or PNG output. Launching host applications from the emulator is disabled by default for security and can be enabled through configuration or a command-line option. The project describes use for DOS software, historical preservation, testing and continued DOS development; emulating Pentium 4-or-higher CPUs and post-2000 PC hardware are listed as non-goals.

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.
