The most useful cores are those that are original'''Sony PlayStation'''* SCPH5500. These are the PS1, PCE, PCbin -FX and Virtual Boy cores(NTSC-J) Required for Japan-region games. The PCE core is one of the best emulators * SCPH5501.bin - (NTSC-U) Required for that system, with a Fast and Accurate versionsNorth America/US-region games. The PS1 core is native resolution only, and features high degree of accuracy and compatibility* SCPH5502. The Virtual boy core is one of the best, although it does not attempt to reproduce the 3Dbin - (PAL) Required for Europe-region games.
Other cores improve upon emulators that have been long abandoned and rarely updated. These include the Neo Geo Pocket, WonderSwan Color and Atari Lynx cores'''NEC PC Engine CD'''* syscard3.pce
Other cores are less useful, as there are better options in stand'''NEC PC-alone emulators. NES, Genesis, Master System and SNES. These cores might even be based on out dated versions. For instance, the SNES core is based on an old outdated version of bSNES.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 RyphechaFX'''* pcfx.bios
It is unknown at this time whether Mednafen's GBA core is better than VBA''Sega Saturn'''* sega_101.bin - Required for Japan-region games.* mpr-17933.bin - Required for North America/US-region and Europe-region games.For ST-MV games, use the original uncompressed files inside stvbios.zip from MAME romset.
[[RetroArch]] uses ===CUE===For most systems, Mednafen only needs the PS1ROM file; but to load PlayStation games, PCE, Neo-Geo Pocket, Virtual Boy, and WonderSwan cores of Mednafen so it might make sense requires CUE sheets to use know where the music data is. Ensure that insteadthe CUE sheet is properly set up in order for the game to run. See the [[Cue sheet (.cue)]] page for more info.
Most systems do not require any bios except for PS1, PCE-CD and PC-FX that need to be placed into a folder called "firmware" in your mednafen directoryGame (Disc 3). Mednafen is very picky about which BIOS to use. The ones that you might need are:cue
PS1:Save the .txt file and then change the file extension to .m3u. Run the .m3u, rather than the .cue of the first disc and the first disc will load. When you get to the end of that disc, the next disc will be automatically loaded.For this method to work, shared memory cards (see below) must be used for the games in the playlist.

*SYSCARD3===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.PCEPC-FX:
===Dual Analog Controllers with PS1===* md.correct_aspect 0To use analog sticks and the rumble feature of Dualshock controllers open the mednafen-09x* nes.cfg file search for "psxcorrect_aspect 0* pce_fast.inputcorrect_aspect 0* snes.port1" and change gamepad to dualshock. Do this for port2 if you wish to play multiplayer games with the features of dualshock controllerscorrect_aspect 0* snes_faust.correct_aspect 0===Configuring Controls===Once in game to configure your controller at any time press 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* ss.correct_aspect 0
===Graphical Enhancements=======Sprite Limit====On older systems due to hardware limitations only Here is also a little list of the cores without an correct_aspect setting but its width is still wrong, so many sprites could be on screen at the same timechanging its xscale values will give pixel perfect. Most systems got around this limitation but alternating These cores (except PC-FX) also have a boolean setting called h_overscan which if it's enabled (1) some overscan (which sprites were is most known as black bars) on screen each refresh causing the sprite to both sides will appear to flicker, but width size is still inaccurate. Mednafens default settings All values are true to the original system limits but in the cfg file this limitation can be removed. Here is the list of options replaced from the cfg file to change from 0 to 1 1X scale, if you don't wish to have the limitwant 2X or 3X scale, multiply it with a calculator.

==NetPlay==Cores that work The cheat engine interface is command-based but still easy to use. Each time a menu appears, you have a bunch of options with NetPlay:*TG-16/PC Engine/PC-CD/SuperGrafx a number (or key) before each choice. You're supposed to write the number (option # just means to choose the number for both accuracy and fast coresthe line you want)*PCor letter standing for your choice. Occasionally, when asked to input some values or names, a value appears between brackets after the question -FX*NES*Genesis (experimental but mostly functional; 2 Players only)*Master System*SNES*Playstation 1if that's what you want to write down, you can simply leave the entry field empty and press Enter.

==ReviewUsing Mednafen==It is Officially Mednafen has only a command -line onlyinterface, 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 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 hard 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 new usersaccept 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:
==Using Mednafen=Loading a game===Its pretty easy to get up To load a game in Mednafen, simply drag and runningdrop your ROM or CUE file onto mednafen. You exe, or if you prefer, you can use a frontend like medguithe command line. Mednafen requires no special commands, such as the desired system. HoweverFor example, a good text editor in Windows, the command would look like [httpC:/Emulators/Mednafen/wwwmednafen.notepad-plus-plus.orgexe C:/Roms/Nintendo/ Notepad++] is all you need if you need to change settingsbattletoads.nes ===Biosm3u playlist files===[[File:M3u_example.png|thumb|right|206px|An example of a .m3u for Valkyrie Profile]]To automatically load the next disc of a game, you will need a .m3u file. To make one, simply create a text file and name it after your game. Within the text file, write the names of the .cue sheets for your game discs as such: Game (Disc 1).cue Game (Disc 2).cue
===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.

===CUE=Width size corrections==For most systems Mednafen only needs the rom file but 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 the game to run. See the [[Cue sheet (.cue)]] for more.===Loading a game===In mednafen to load Some cores have a gamewrong width resolution, simply drag doubt if this is a bug and drop your rom or cue file onto the mednafen.exe or even less a problem, but if you prefer want some pixel perfect (to see better horizontal scrolling for example) you can use the command line.

The goal of these searches is to narrow down the list of results to a single or handful of addresses (variables) pertinent directly to whatever we're searching for. The search always starts with "Reset Search", going back in-game (Alt+C) to play and change stuff, then back to the cheat engine to compare the "Original" value with the "Current" value. Then 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). 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):
# '''O==V1 && C==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 you don't write the old value again, and write the current value under C.
# '''O==V1 && |O-C|==V2''' same, but instead of writing the current value you write by how much it changed (0 if old value equals new value)
# '''|O-C|==V2''' you write by how much it changed (0 if old value equals new value)
# '''O!=C''' if old value doesn't equal new value
# '''Value decreased''' if new value smaller than old value
# '''Value increased''' if new value bigger than old value

==Memory cards==
===Shared memcards===
Use this so that there is a shared memory cards for all games:
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.
* 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====
Another option is to use Memory Card Manager 1.4 to extract a separate game saves from a shared memory card file.
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).

#* "Port" where you'll choose one an open TCP/UDP one
#* "Password" which you can establish or leave blank
# When you're done fiddling with your settings, click Create standard.conf
# Click Create Server. A cmd window will appear.
# Click My IP to obtain your external IP address and share it along with your port to your friend(s).
# Launch the game.
# Press T, and type /server localhost.
# Wait for other people to connect.
'''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.
#* "Local player" is the number of players that will also be playing on one computer.
#* "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.
