-==== DOSBox Emulation: Basic rundown ====
+How exactly they are setup and what additional configuration is require depends on which emulator you use. For first time users, [[#libretro:_dosbox_pure|libretro: DOSBox_Pure]] is recommended.
-Here's a simple example with the game Alley Cat :
+<WRAP center round tip>
+If intending on using DOSBox_Pure, ''.zip'' files can be renamed to ''.dosz'' (It is a relict from the libretro frontend that wants to load the content of ''.ZIP'' files instead of sending it to DOSBox Pure to load. This was especially useful for CD images in ZIP format which RetroArch refuses to append through its Disc Control menu. So for fun? ... FIXME - yes it is rather a joke because BATOCERA is an advanced launcher where each system is separated and a dependency to a file suffix does not exists).
+In addition, to mount a ZIP file as the virtual ''A:'' or ''D:'' drive the ''.zip'' file can be renamed to ''.d.zip''.
+</WRAP>
+===== Emulators =====
+==== DOSBox ====
+The most standard version of DOSBox. Can be a bit unwieldy to use for newcomers, but it provides the most "pure" experience of DOSBox. Those already familiar with DOSBox will be right at home.
+Requires [[#dosbox_standalone_preparation|some setup]] before games can be run in it.
+<WRAP center round tip>
+New users are recommended to use [[#libretro:_dosbox_pure|libretro: DOSBox_Pure]] instead when starting out.

+=== DOSBox configuration ===
+Standardized features available to all cores of this emulator: ''dos.videomode'', ''dos.ratio'', ''dos.padtokeyboard''
+==== DOSBox_Staging ====
+[[https://dosbox-staging.github.io/|DOSBox Staging]] is a fork aimed at ease-of-use. Prioritizes running games, while still striking a balance between emulation quality, speed, and usability.
+=== DOSBox_Staging configuration ===
+Standardized features available to all cores of this emulator: ''dos.videomode'', ''dos.ratio'', ''dos.padtokeyboard''
+There are no configuration options available yet.
+==== DOSBox-X ====
+Vastly different from all the other forks, [[https://dosbox-x.com/|DOSBox-X]] aims to support Windows 3.x, 9x and ME games in addition to all the already emulatable DOS games.
+<WRAP center round todo>
+How do you use this, though?
+</WRAP>
+==== RetroArch ====
+RetroArch has [[emulators:retroarch|its own page]].
+=== libretro: DOSBox_Pure ===
+Noob-friendly DOSBox, [[https://github.com/schellingb/dosbox-pure|DOSBox Pure]] aims for simplicity and ease of use. Aims at automating the entire process, including pre-configuring everything you might need for a game such as input mapping and batch script creation. This core doesn't require as much setup as the others do, and leverages RetroArch's functionality in addition to DOSBox's. Notably, when launching a game's folder DOSBox Pure will prompt the user for which executable file to launch, instead of requiring a run command to be typed out manually and saved to a file using external tools.
+Because of its automated nature, it can be difficult to handle issues when they arise. If a particular game you have doesn't work with DOSBox Pure, it is recommended to try them on the standalone DOSBox emulators (after properly setting them up for them, of course).
+While in DOSBok_Pure, run ''REMOUNT C: D:'' to remount the loaded game files in the ''D:'' drive.

+===== DOSBox standalone preparation =====
+<WRAP center round tip>
+New users should first use [[#libretro: dosbox_pure|DOSBox_Pure]]. It does not require this same level of setup, just put your game's files in a ''dos/<game name>.pc/'' folder and run it.
+</WRAP>
+The standalone DOSBox versions require some setup for each game before they can be run.
+Here's a simple example with the game Alley Cat:
   * Start by creating a folder for your game named ''AlleyCat.pc''. The first part of the folder name before the '.' must have equal or less than 8 characters and avoid special characters.
   * Inside it create a ''dosbox.bat'' file and edit it to call the executable of the game (For big games it's better to install them on your computer before copying them to Batocera).\\ Here for Alley Cat that gives us:
