Replacements
Listings that take over the same core job as Ymir.
Mednafen
Command-line multi-system emulator covering Saturn, PlayStation and more.
Mednafen is command-line driven with a text-file configuration and no real graphical interface, but its Saturn emulation is among the most accurate available and it also covers PlayStation.
RetroArch
One front end for dozens of emulators, with unified settings, shaders and a controller setup you only do once.
RetroArch runs emulator cores under one front end with shared settings, shaders and controller setup on desktop and mobile, but you must download cores and supply BIOS files.
BizHawk
A multi-system emulator built for tool-assisted speedrunning, with rewinding, frame stepping, memory search and input recording.
BizHawk covers many systems with rewinding, frame stepping and input recording for speedrunning, but runs only on Windows and Linux and its cores are less accurate than dedicated emulators.
MAME
Documents and recreates thousands of arcade machines, consoles and old computers, with accuracy as the point.
MAME documents thousands of arcade machines, consoles and computers with accuracy as its priority, but later hardware needs a fast machine and its interface is basic.
