Mednafen only has a command line interface, so its interface might be hard to use to new users.

==Using Mednafen==

===BIOS===

* syscard3.pce

* sega_101.bin

* mpr-17933.bin

===CUE===

===Loading a game===

For this method to work, shared memory cards (see below) must be used for the games in the playlist.

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.

===Graphical enhancements===

====Sprite limit====

* [{{MednafenURL|documentation/nes.html#nes.no8lim}} nes.no8lim]

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 Lives:''' It's game over when the internal variable for "Lives" is 0. So in some cases, when it shows "REST/LEFT=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. Lose a life, search for variables equal 2, and so on.

* '''Character Modifier / Level Modifier / Having 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. In-game, change it, then do a new value doesn't equal old value. And so on.

* '''Debug Modes:''' stuff that stays 0 no matter what, extra off-screen inaccessible options in menus, extra dialogue... you name it. Have fun experimenting.

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 && |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)

Here's the full documentation: {{MednafenURL|documentation/fname_format.txt}}

===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.

* 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.

==Frontends==

Cores that work with netplay:

{| class="mw-collapsible mw-collapsed wikitable" style="width: 100%;"

* Netcode allows for people to join a game that's already in session

* In-game chat

|-

| '''CONS''' ||

* Command-line only (you can use a frontend, though)

* Weird, convoluted settings (or lack thereof)

* Only supports 2 players on Genesis

* Frontend doesn't always save settings correctly

# Run MedGui.exe

# You'll get a small window. On your left, you'll see two arrow buttons with a console/handheld icon in between. Choose your desired platform.

# Pick your game.

# Click the button with a checkered red ball and joystick to start the game.

# When you're done fiddling with your settings, click Create standard.conf

# Click Create Server. A cmd window will appear.

# Launch the game.

# Press T, and type /server localhost.

#* "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.

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.
