+# Emulators
+
+An Emulator is a hard- or software that enables a computer to behave like
+another computer.
+In the gaming context this is mainly used to run games from a console on
+another computer.
+Emulators usually need ROMs to run games.
+ROMs are a digital copy of a video game.
+
+## List of Emulator software
+
+- [PPSSPP](./ppsspp.md) is made to emulate Playstation Portable games

+# PPSSPP
+
+[PPSSPP](https://ppsspp.org/) is a Playstation Portable (PSP)
+[emulator](./emulators.md).
+
+## Setup
+
+PPSSPP can be installed on different systems, a list for this can be found on
+the [PPSSPP website](https://ppsspp.org/downloads.html).
+Additionally it can be installed using [Flatpak](../linux/flatpak.md) where the
+package is called `org.ppsspp.PPSSPP`.
+
+## [Steam Deck](./steam.md#steam-deck) specific settings
+
+The following settings are especially useful when emulating PSP games on the
+[Steam Deck](./steam.md#steam-deck) as pointed out by
+[nchristopher](https://github.com/nchristopher/steamdeck-emulation/blob/main/emulators/ppsspp.md).
+But it is a good starting point for other systems aswell.
+It is important to emphasize that the system needs to meet the requirements to
+run Vulkan.
+The Device name will change if you are not using a
+[Steam Deck](./steam.md#steam-deck).
+
+```txt
+Backend: Vulkan
+Device: AMD RADV VANGOGH
+Fullscreen: on
+VSync: on
+Rendering solution: Auto (1:1)
+Upscale level: 2x
+Upscale type: Hybrid + Bicubic
+Deposterize: on
+```
+
+## Running a game without selection in the menu
+
+To run a game instantly the path to the [ROM](./emulators.md) needs to be
+appended to the command used for starting PPSSPP.
+This should be made in quotation marks as it could contain characters that need
+to be escaped.

 Wine prefix completely.
 It is recommended to keep a backup of the folder containing the old Wine prefix
 as it stores game saves and other important data, that can be useful.
+
+## Adding non-Steam Games
+
+Games that are not in the Steam store can be added to the Steam application.
+This is done by opening (the desktop mode) of Steam and selecting
+`Add a Non-Steam Game to My Library` under the `Games` tab in the top left
+corner.
+A dialog window will open to select the software to add to steam.
+Check the box or boxes of the software to add to Steam and tap
+`Add Selected Programs`.
+
+For games such as launchers a `Launch Option` can be set most of the time to
+skip the launcher and go directly into the specified game.
+This option usually mirrors the command that would be used in the command line
+of a system to go directly into the game.
+Often this is done by simply appending the path of the specified game to the
+command but this can also differ depending on the launcher.
+
+## Setting Icons and Banners for Games
+
+Images for games can be changed by downloading them and applying them manually.
+An easier route can be taken by using
+[SGDBoop](https://www.steamgriddb.com/boop).
+To use it, you first need to install it.
+It is available in the [flatpak package manager](../linux/flatpak.md).
+After that navigate to the
+[SteamGridDB website](https://www.steamgriddb.com/boop) and log in with your
+steam account.
+Follow the remaining steps as described on the website.
+Following this different images, banners and icons can be found on
+[the website](https://www.steamgriddb.com/).
+When hovering over an asset a little blue button will appear.
+On the press of the button a game can be chosen that will use the asset in the
+steam application.
+This works for both Steam and non-Steam games.
+
+## Steam Deck
+
+The [Steam Deck](https://store.steampowered.com/steamdeck) is a handheld gaming
+computer made by the same developers as Steam.
+Due to its form factor it can be used especially well to play games that need a
+controller, such as many games that run on [emulators](./emulators.md).
+But by adding a USB-hub and connecting keyboard and mouse it can be used to
+play classical PC games aswell.
