Mednafen is an acronym Many of its cores are ports of other emulators; however, many of its cores are also original and are notable for "My Emulator Doesn't Need A Frickin' Excellent Name"their high quality, compatibility and accuracy.<br />

The NEC PC Engine core is one of the best emulators for that system, with a Fast and Accurate version. The PlayStation core is native resolution only and features a high degree of accuracy and compatibility<ref>[http://mednafenforum.sourceforgefobby.net/releasesindex.php?t=msg&th=1114 Mednafen PSX bugs reports]</ref>. The Nintendo Virtual Boy core is one of the best for the system. Some cores improve upon emulators that have been long abandoned and rarely updated. These include the SNK Neo Geo Pocket/Color, Bandai WonderSwan/Color, and Atari Lynx cores. Other cores are less useful, as there are better options in stand-alone emulators (Nintendo Entertainment System, Sega Genesis, Master System, and Super Nintendo Entertainment System). These cores might even be based on out-dated versions. For instance, the Super Nintendo Entertainment System core is based on an old, outdated version of bsnes. This is before the performance/accuracy/ balanced cores — 0.50x territory — with a couple of changes by Ryphecha. It is unknown at this time whether Mednafen's Nintendo Game Boy Advance core is better than [[VisualBoy Advance#VBA-M|VBA-M]] Official releases. 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 under the name "Beetle", so it might make more sense to use [[RetroArch]] instead. Version 1.31.0 added experimental support for [https://system16.com/hardware.php?id=711 ST-V games] that don't require decryption chips or special hardware. Refer to the [https://mednafen.github.io/documentation/ss.html#Section_stv ST-V section of the official documentation] for more details and a list of explicitly supported games.
The best ===BIOS===Most cores in Mednafen are those that are original - which are do not require any BIOS except for the PS1Sony PlayStation, PCENEC PC Engine CD, PC-FX , and Virtual Boy Sega Saturn cores. The PCE core is one of the best emulators for that system, with BIOS files need to be placed into a Fast and Accurate versionfolder called "firmware" in your Mednafen directory. The PS1 core Mednafen is native resolution onlyvery picky about which BIOS to use, and features high degree but all of accuracy these come with the [[Emulator_Files#Multi-System|Mednafen BIOS pack]] and compatibilityare correctly named. The Virtual Boy core is one of the best for <ref group=notes>Mednafen can be forced to accept incorrect bios roms by editing its config file if you absolutely cannot find the systemcorrect ones, although it does not attempt to reproduce the 3Dbut this may cause compatibility problems.</ref> The ones that you might need are:

All of these come with the [[Emulator_Files#Multi-System|RetroArch BIOS pack]], and are correctly namedGame (Disc 3).cue
===CUE===For most systems, Mednafen only needs Save the .txt file and then change the rom file; but extension to load PS1 games, Mednafen requires CUE sheets to know where the music data is. Ensure that the CUE sheet is properly set up in order for m3u. Run the game to run. See m3u, rather than the [[Cue sheet (.cue)]] page for more info. ===Loading a game===To of the first disc and the first disc will load a game in Mednafen, simply drag and drop your rom or CUE file onto mednafen.exe, or if When you prefer, you can use get to the command line. Mednafen requires no special commandsend of that disc, such as the desired systemnext disc will be automatically loaded. For examplethis method to work, shared memory cards (see below) must be used for the games in Windows, the command would look like C:/Emulators/Mednafen/mednafen.exe C:/Roms/Nintendo/battletoadsplaylist.nes
===Cheats===Here is also a little list of the cores without an correct_aspect setting but its width is still wrong, so changing its xscale values will give pixel perfect.Mednafen supports the usual cheats such These cores (except PC-FX) also have a boolean setting called h_overscan which if it's enabled (1) some overscan (which is most known as GameSharkblack bars) on both sides will appear, but width size is still inaccurate.All values are replaced from 1X scale, Code Breakerif you want 2X or 3X scale, and Action Replay. The cheats menu can be accessed multiply it with ALT+Ca calculator.

==Issues==<gallery>===Mednafen memory cards===File:mednafenpsxbefore.png|2.0X scaleTo transfer memory cards, follow this guideFile:mednafenpsxafter. Also, in games with multiple discs with saves that carry over, you have to follow the same procedurepng|2.1875X scale</gallery>
[[Using RetroArch#Transfer_PS1_Memory_Card_Files]]===Cheats===Mednafen supports the usual cheats such as GameShark, Code Breaker, and Action Replay. The cheats menu can be accessed (or quit back to normal gameplay) with '''ALT+C'''.
==Frontends=====Medgui===To add an existing GS/AR/PAR/CB cheat code, use "Gameshark Codes". Else, if you have a memory address and a given value for it, choose "Search Code" then "Add Code", then put in the address (as $XXXXXXXX), the byte range depending on the values your variable can take (1 is 0-255, 2 is 0-65535, etc), and the numeric value proper (in decimal, or hexadecimal if followed by a lower-case h). Various cheat types exist too (S(substitute on read), C(substitute on read with compare) or R(Windowsreplace value before vblank) -- R being the default recommended option)http://sourceforge.net/projects/medgui/
===MedGui Reborn===Searching for new cheat codes is also possible. The general idea being comparing variables, going back to gameplay so that this variable changes, then back to the cheat engine searching for any variables that changed in that particular way. For example:* '''Infinite Health / Ammo / Time / Money:''' you start with 5 hearts, reset search (Windowsin the cheat engine, not reset the game you silly!), you get hurt to 4 hearts, search variables that decreased, get healed back to 5 hearts, search variables that increased, and so on. For the money, you can start with 0 when you have 0 gold and try earning/spending money. You could try using save states as well when you don't have as much freedom changing the value. [http* '''Infinite Lives:''' It's game over when the internal variable for "Lives" is 0. So in some cases, when it shows "REST//forumLEFT=1" in-game and you lose a life then it becomes 0 but you're still allowed to play on your last life, that means the internal counter for lives has actually changed from 2 to 1 and not from 1 to 0, but in other games (where if you die on "LIVESx1" it's game over) it's not the case. In the case of lives, you actually know the exact value: reset search initially, then (if you have 2 lives on a game that allows you to play on "LEFT=0") search for variables with values equal to 3.fobbyLose a life, search for variables equal 2, and so on.net* '''Character Modifier / Level Modifier /indexHaving an Item:''' reset search, play without changing whatever you're searching for (let's say the stage), do lots of searches for new value equals old value.php?In-game, change it, then do a new value doesn't=msgequal old value. And so on.* '''Walk Through Walls / Invincibility / In-game Cheats &th=924&start=0& httpFeatures:''' you need to find the value that tells the character if he can move or not (he can't really move when walking against a wall) /if he's blinking or being invincible right now after getting hurt. Same methods as before, but there are hints that could be useful here -- both states could be 0/forum1, or something else.fobby.net/index.php?t=msg&th=924&start=for example, one could assume 0 is not enabled and 1 is enabled.* '''Debug Modes:''' stuff that stays 0&]no matter what, extra off-screen inaccessible options in menus, extra dialogue... you name it. Have fun experimenting.
===Mednaffe===The goal of these searches is to narrow down the list of results to a single or handful of addresses (Multivariables) pertinent directly to whatever we're searching for. The search always starts with "Reset Search", going back in-platformgame (Alt+C)https://codeto play and change stuff, then back to the cheat engine to compare the "Original" value with the "Current" value.googleThen you check the results page which must get smaller and smaller (if it's 0 results, you screwed up and need to reset search to try again).com/p/mednaffe/The comparing options offered by Mednafen are as follow, with O being the Original value, and C being the Current value (when you reset a search, they're the same):

'''Mednafen''' (an acronym for '''My Emulator Doesn't Need A Frickin' Excellent Name''', formerly '''Nintencer''') is a an open-source, [[Multi-System Emulatorssystem 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|PlayStation]] and [[PC Engine (TurboGrafx-16) emulators|PC Engine (TurboGrafx-16)]] original cores are notable for their high quality, compatibility and accuracy.

==OverviewUsing Mednafen==Officially Mednafen has only has a command -line interface, so its that is nevertheless easy to configure and run for users familiar with it. Everyone else can use a [[Frontends#Mednafen|third-party frontend]] for GUI. As with any type of interface might a good text editor like [http://www.notepad-plus-plus.org Notepad++] can be hard to use used to new userschange settings.
==Using Mednafen=CUE===For most systems, Mednafen only needs the ROM file; but to load PlayStation games, Mednafen requires CUE sheets to know where the music data is pretty easy . Ensure that the CUE sheet is properly set up in order for the game to get up and runningrun. You can use a frontend like medgui. However, a good text editor like See the [[http://wwwCue sheet (.notepad-plus-plus.org/ Notepad++cue)]] is all you need if you need to change settingspage for more info.
===BIOSLoading a game===Most cores do not require any BIOS except for the PS1To load a game in Mednafen, PCE-CD simply drag and PC-FX coresdrop your ROM or CUE file onto mednafen.exe, or if you prefer, you can use the command line. [[Emulator_Files#Multi-System|BIOS files]] need to be placed into a folder called "firmware" in your Mednafen directoryrequires no special commands, such as the desired system. For example, in Windows, the command would look like C:/Emulators/Mednafen is very picky about which BIOS to use/mednafen. The ones that you might need areexe C:/Roms/Nintendo/battletoads.nes
===Dual Analog Controllers analog controllers with PS1PlayStation===
To enable analog sticks and rumble on DualShock controllers, open the mednafen-09x.cfg file, search for "psx.input.port1" and change gamepad to DualShock. Do this for port2 if you wish to play multiplayer games with the features of DualShock controllers.
===Configuring Controlscontrols===
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===
====Sprite limit====
This is a feature on older systems, due to hardware limitations, that makes it only display so many sprites could be on screen at the same time. Most systems got around this limitation by alternating which sprites were on the screen each refresh, causing the sprite to flicker. Mednafen's default settings are true to the original system limits, but this can be disabled in the .cfg file. Here is the list of options from the .cfg file to change from 0 to 1 if you don't wish to have the limit.
* [{{MednafenURL|documentation/nes.html#nes.no8lim}} nes.no8lim]
* [{{MednafenURL|documentation/pce.html#pce.nospritelimit}} pce.nospritelimit]
* [{{MednafenURL|documentation/pce_fast.html#pce_fast.nospritelimit}} pce_fast.nospritelimit]
* [{{MednafenURL|documentation/pcfx.html#pcfx.nospritelimit}} pcfx.nospritelimit]
===Graphical Enhancements=======Sprite LimitWidth size corrections====This is Some cores have a feature on older systemswrong width resolution, due to hardware limitations, that makes it only display so many sprites could be on screen at the same time. Most systems got around doubt if this limitation by alternating which sprites were on screen each refreshis a bug and even less a problem, causing the sprite to flicker. Mednafen's default settings are true to the original system limits, but this can be disabled in the cfg file. Here is the list of options from the cfg file to change from 0 to 1 if you don't wish want some pixel perfect (to have the limit.see better horizontal scrolling for example) you must disable Correct aspect ratio in these cores:
*pcfxmd.romcorrect_aspect 0*nes.no8limcorrect_aspect 0*pcepce_fast.nospritelimitcorrect_aspect 0*pce_fastsnes.correct_aspect 0* snes_faust.nospritelimitcorrect_aspect 0*pcfxss.nospritelimitcorrect_aspect 0
The cheat engine interface is command-based but still easy to use. Each time a menu appears, you have a bunch of options with a number (or key) before each choice. You're supposed to write the number (# just means to choose the number for the line you want) or letter standing for your choice. Occasionally, when asked to input some values or names, a value appears between brackets after the question - if that's what you want to write down, you can simply leave the entry field empty and press Enter.
# '''O==NetPlayV1 && C==Cores V2''' if you know the explicit numerical values for the variable, you write it here. The first time, just write the same value in both. Subsequent times, leave O blank and press Enter so that work with NetPlay:you don't write the old value again, and write the current value under C.*PC Engine (TurboGrafx# '''O==V1 && |O-16)/PC-CD/SuperGrafx C|==V2''' same, but instead of writing the current value you write by how much it changed (option for both accuracy and fast cores0 if old value equals new value)*PC# '''|O-FX*NES*Genesis C|==V2''' you write by how much it changed (experimental but mostly functional; 2 Players only0 if old value equals new value)*Master System# '''O!=C''' if old value doesn't equal new value*SNES# '''Value decreased''' if new value smaller than old value*PlayStation# '''Value increased''' if new value bigger than old value
Create '''psx.cfg''', and add the line: '''filesys.fname_sav %s.%X'''<br>
Here's the full documentation: {{MednafenURL|documentation/fname_format.txt}}
Emulation bugs, crashes, and save states can corrupt your memory card data.
===Transfer===
To transfer memory cards, follow this guide. Also, in games with multiple discs with saves that carry over, you have to follow the same procedure.
Mednafen creates memory card files for each individual game, in contrast to [[PCSX-Reloaded]]/[[ePSXe]] where all game saves are stored into 2 memory card files. To transfer memory card files from PCSX-Reloaded/ePSXe to [[RetroArch]]:
* Start the game in RetroArch.
* Go to the system folder. Copy the names of the .mcr files created for the game.
* Delete them.
* Rename the files you want to transfer with the names of the RetroArch memcard files.
* Place the new ones in the system folder.
====Using Memory Card Manager 1.4====
The utility has support for next memory card formats: *.mem, *.mcd, *.mcr, *.gme, *.ddf, *.psx, *.ps, *.psm, *.vmp, *.VM1
[[File:memory_card_manager.png|400px]]
It allows to transfer each of the game saves from a shared memory card to a .mcr memory file used by Mednafen. As it was described above, you just need to start game and check for '''sav''' folder inside Mednafen system directory. Open with Memory Card Manager 1.4 the memory file created for your game by Mednafen and open the shared memory card file from which you wish to transfer a save entry. When there would be a dialogue 'Do you want to replace 'SAVE_ENTRY_NAME' click 'Yes' and then save the file to the '''sav''' folder (the older one should be replaced).

'''If you're Connecting:'''
# In the Netplay-Client section, you have the following options:
#* "Host", which is the server's IP you'll connect to
#* "Port, which is the one used by the server (which you should also have open on your end).
#* "Password", blank if there is none.
#* "Nickname" where you type whatever you want.

#* "Small font" which makes the chat font smaller.
# When you're done fiddling with your settings, launch the game.
# Press T, and type /server IP_goes_here.
You can chat in-game by pressing T. Also, remember that you can drop in and out of the game at any time, so you don't need to reset the game if someone accidentally disconnects.
There are way too many settings, commands , and features to list, so take a look at the emulator's documentation.
