[[RetroArch]] uses the Mednafen's Sony PlayStation, NEC PC Engine(Fast, not Accurate, version), SNK Neo Geo Pocket/Color, Nintendo Virtual Boy, Sega Saturn and Bandai WonderSwan/Color emulators are all available as [[libretro]] cores of Mednafenunder the name "Beetle", so it might make more sense to use that [[RetroArch]] instead.

→Netplay: Lack of CHD support is unacceptable, even by today's standards. It is the emulator's one of biggest flaws, while fatal flaw is its command-line only nature; that concept is obsolete.

'''Mednafen''' (an acronym for '''My Emulator Doesn't Need A Frickin' Excellent Name''', formerly '''Nintencer''') is an open-source, [[Multi-system emulators|multi-system emulator]], driven from the command-line. Many of its cores are ports of other emulators, but many of them are also original. Its [[PlayStation emulators|Sony PlayStation]], [[Sega Saturn emulators|Sega Saturn]], [[Virtual Boy emulators|Nintendo Virtual Boy]], and [[PC Engine (TurboGrafx-16) emulators|NEC PC Engine (TurboGrafx-16)]] original cores are notable for their high quality, compatibility and accuracy.

It is unknown at this time whether Mednafen's Nintendo Game Boy Advance core is better than [[VisualBoy Advance#VBA-M|VBA-M]].
==Using Mednafen==
Officially Mednafen has only a command-line interface, that is nevertheless easy to configure and run for users familiar with it. Everyone else can use a [[Frontends#Mednafen|third-party software for graphical interfacefrontend]]for GUI. Also, As with any type of interface a good text editor like [http://www.notepad-plus-plus.org Notepad++] can be used to change settings.
===BIOS===
Most cores do not require any BIOS except for the Sony PlayStation, NEC PC Engine CD, PC-FX, and Sega Saturn cores. BIOS files need to be placed into a folder called "firmware" in your Mednafen directory. Mednafen is very picky about which BIOS to use, but all of these come with the [[Emulator_Files#Multi-System|Mednafen BIOS pack]] and are correctly named. <ref group=notes>Mednafen can be forced to accept incorrect bios roms by editing its config file if you absolutely cannot find the correct ones, but this may cause compatibility problems.</ref> The ones that you might need are:
'''Sony PlayStation'''
===Configuring controls===
Once in-game, to configure your controller at any time, press Alt+Shift+1 and it will guide you through the setup. Press Alt+Shift+2 and so on for each additional controller for multiplayer.
To emulate a different kind of controller, Ctrl+Shift+1 (or 2 for port 2 etc) to cycle through known controller types.
If you're having trouble with a controller with analog buttons (the Namco neGcon, for example), hit F3 to make Mednafen detect them.
===Graphical enhancements===
====Width size corrections====
Some cores have a wrong width resolution, doubt if this is a bug and even less a problem, but if you want some pixel perfect (to see better horizontal scrolling for example) you must disable Correct aspect ratio in these cores:
* PlayStation (h_overscan 1): 1.09375
===Cheats===
* Super Nintendo Entertainment System
* Sony PlayStation
* Sega Saturn (experimental)

| '''CONS''' ||
* Command-line only (you can use a frontendthankfully, thoughfront-end GUI for this emulator exists)
* Weird, convoluted settings (or lack thereof)
* Super Nintendo Entertainment System emulation will be slow to you if you're on a low-end computer (uses bsnes core)
* Sony PlayStation core is accurate but slow
* Only supports 2 players on Genesis
* No CHD file support
