This guide presents 3 different ways to play flash games on your deck, ordered by complexity. This is actually a remake of a guide I had previously made on Reddit, but seeing as that platform is failing, I wanted to move this guide elsewhere, taking the time to recreate it.
Here are some videos covering the stuff here (not by me, though):
Basic Guide (Discover Store Method)
To start off, first open up the Discover Store and search "Adobe Flash Player". Install the entry that looks like this:
![Screenshot of the app page for "Adobe Flash Player" on the Discover Store](https://files.catbox.moe/mn8zha.png)
Next, acquire some SWF files (flash games). You can find these in many places, but I've found that a game's speedrun page will most likely have the SWF file for that game. After downloading, use the Dolphin file manager to place these files in an easy to find spot.

Finally, open up the Flash Player installed from the Store. At the top left of the window, hit File > Open. Select any of the SWF files you've acquired. You are now playing a Flash game.

You can make a custom control configuration for Flash by adding the Flash Player as a non-steam game. This will enable you to use keyboard controls with your Deck's inputs. (At this point however, you might as well use the next guide).
Limitations with this method
- Unable to play most Flash Games (see beginning of Intermediate Guide)
- Requires you to search for SWF files
- Only 1 app, therefore only 1 controller configuration possible for all of your flash games
Benefits with this method
- All Flash Games are in one place with little extra configuration
Intermediate Guide (Flashpoint + Proton)
You may have noticed with the Basic Guide that some (if not most) Flash Games do not work. This is because many Flash Games rely on a connection to an external server; the Discover Store Flash Player cannot simulate this connection. Another app, Flashpoint, does simulate this connection, and is what will be installed in this guide.
Installing Flashpoint & CLIFp
Begin by going to the Flashpoint download page and downloading the Windows EXE of Flashpoint Infinity.
![Screenshot of the Flashpoint Download Page with the correct link highlighted](https://files.catbox.moe/jqlghw.png)
Next, open up Dolphin and find the downloaded file. Change its extension from .exe to .7z. Open the file with Ark and extract its contents to a place that's easy to find.
![A screenshot of the downloaded EXE file in Dolphin, which points to a screenshot of the file with the changed extension, followed by the archive open in Ark](https://files.catbox.moe/g6y2xd.png)
Your Flashpoint folder should now look like this.
![Screenshot of the Flashpoint folder just after extraction](https://files.catbox.moe/xqfpcf.png)
We will now need to download an app called CLIFp, which we need as Flashpoint's normal GUI crashes on Steam Deck. Go to the releases page of CLIFp and Download the latest Windows Static build.
![Screenshot of the CLIFp Download Page on the latest release with the Windows Static Build highlighted](https://files.catbox.moe/0vgxii.png)
Extract the contents with Ark, and find CLIFp.exe
under bin/. Move CLIFp.exe
to the Flashpoint folder.
![Screenshot of the contents of the extracted folder, with an arrow pointing to the bin/ folder.](https://files.catbox.moe/34a74b.png)
Your Flashpoint folder should now look like this.
![Screenshot of the Flashpoint folder with CLIFp.exe in place, next to start-flashpoint.exe](https://files.catbox.moe/vo1bso.png)
Adding Games
Once CLIFp is in the correct place, add CLIFp.exe
as a non-steam game. Go to the properties page for CLIFp, and enable Proton for CLIFp (any modern version should work).
![Screenshot of the properties page for the CLIFp.exe non-steam game on the compatibility section](https://files.catbox.moe/01wbyu.png)
All that's left is to specify which game CLIFp should launch. Go to the Flashpoint Search Tool, and search for the game you want to play. Find its ID (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx), and copy it.
![Screenshot of the Flashpoint Database search page showing the ID section of Super Mario 63. Contains the text "Be aware of additional apps. Most likely, the right ID is not the one at the bottom."](https://files.catbox.moe/x8wprr.png)
With the ID copied, all that's left is to add some launch options to CLIFp. Open up the properties page for CLIFp again, and under launch options, add play -i [ID]
, where [ID]
is the ID you previously copied. Now, your game is ready to play.
![Screenshot of the properties page for the CLIFp.exe non-steam game, where the launch options are added into their section and the game is renamed to Super Mario 63](https://files.catbox.moe/s6jbvx.png)
You can add as many CLIFp non-steam games for as many Flash games as you want to play. Do be aware of the following limitations, however.
Limitations with this method
- Each flash game requires a ~200MB Proton prefix that gets stored on the Deck's internal drive. This fills up storage quickly, depending on how many games you wish to play.
- Some games (much less than with the Basic Guide) still do not work. Some may show a white screen, others may not play properly.
Benefits with this method
- Much more Flash games work this way.
- Each Flash game can have its own custom controller configuration
- You do not need to search for game SWFs
Advanced Guide (Flashpoint Script)
This guide requires the most setup, but will provide the best possible experience.
Acquiring Scripts
Before starting the Advanced Guide, install Flashpoint and CLIFp. This is covered in the first few steps of the Intermediate Guide. You can continue with the advanced guide once CLIFp.exe
is in the correct place.
You will need to acquire 2 user scripts for this step. Check out and download each script, making sure to place them in your Flashpoint directory and setting each as executable in their properties:
Each script targets Proton 7.0 by default. If you want to use a different version of Proton to run your games, you will need to go into the scripts and change the path in $proton_bin
.
Script 1 plays games through Flashpoint, and should be used by default. If a game does not work with Script 1 (white screen), you may try Script 2 (YMMV with it, however).
I recommend renaming each script. I renamed Script 1 to fp.sh
and Script 2 to fp-direct.sh
.
![Screenshot of the Flashpoint directory with the added shell scripts](https://files.catbox.moe/lutft2.png)
Acquiring wmctrl
You will also need wmctrl. You don't need to disable readonly mode to do this, just download the package here. Create a directory called .wmctrl/
in the Flashpoint directory, and place the extracted contents of the package in it. (You can remove everything other than the usr/
file if you want.)
![Screenshot of a split dolphin view showing the contents of the wmctrl package and the Flashpoint directory. There is some text underneath the package contents, which say "Only the usr/ directory in the downloaded package needs to be placed in .wmctrl"](https://files.catbox.moe/oo2s5b.png)
Adding & Configuring Games
With your scripts in place, go to the Flashpoint Search Tool, and search for the game you want to play. Find its ID and copy it.
![Screenshot of the Flashpoint Database search page showing the ID section of Super Mario 63. Contains the text "Be aware of additional apps. Most likely, the right ID is not the one at the bottom." The screenshot is identical to one in the Intermediate Guide.](https://files.catbox.moe/x8wprr.png)
Now you can add Script 1 as a non-steam game. After adding the script, go to its Launch Options. Add --uuid [ID]
, where [ID]
is the ID you copied previously. Launch the game once; if you see a white screen, try using Script 2 instead.
![Screenshot of the properties page for Script 1. The launch options contain the options presented above. The game is customized to look like an entry for "Pixel Quest."](https://files.catbox.moe/ztaqji.png)
Configuring Window Size
These next few steps are not strictly necessary, but they allow you to configure the window size for the best experience in Gaming mode.
With the game open in desktop mode, make note of the window title and the size of the game window while not in fullscreen. Use the size of the game window to calculate its aspect ratio (divide width by height). Spectacle (the screenshot tool) may be useful as it allows you to see how large any part of the screen is.
If you want to use the original window size, simply use the measurements you got. If you want to fill the Deck's screen size, use 800 for the height and 800 * the aspect ratio for the width.
Go into the game properties for the Flash game. Add --winname [name] --width [width] --height [height]
, where [name]
is the name of the window, [width] is the desired width, and [height] is the desired height. Now, the game will automatically resize itself after starting up.
![Screenshot of the properties page for the same game shown in the last screenshot. The new flags are highlighted.](https://files.catbox.moe/lrj724.png)
Limitations with this method
- Configuring window sizes can be tedious for every single game
Benefits with this method
- No need to bind a "fullscreen" key for a controller configuration
- Does not generate a large proton prefix for each Flash game (only 1)
Bonus Guides
These are just some extra guides that I feel could be potentially useful.
Flash Game Launcher (for Advanced Users)
You may miss having one place to play all of your Flash Games from the Basic Guide, or you may want something like EmulationStation for Emulated Games. While there isn't a solution specifically for Flash Games, I've found Pegasus Frontend to be good for this purpose.
![Screenshot of the Pegasus Frontend (Launcher) with the Library theme, showing a collection of Flash Games listed in a grid.](https://files.catbox.moe/h7dhld.png)
In order to add Flash Games to Pegasus, you must first set up the scripts present in the Advanced Guide. With that done, a basic metadata.pegasus.txt
file for Flash Games (with the script called fp.sh
) should look like this:
collection: Adobe Flash
shortname: flash
command: /path/to/Flashpoint/fp.sh --uuid "{file.basename}"
game: My Flash Game
file: 16b04977-f714-4239-b343-b759e16a33af
...
game: My Other Flash Game
file: a8591065-1c64-4242-a2fc-99f16766aed9
command: /path/to/Flashpoint/fp.sh --uuid "{file.basename}" --winname "Adobe Flash Player" --width 1066 --height 800
...
Using Bottles instead of Proton
Though Proton is a useful option, you are able to do the same thing with Bottles.
You'll first need to enable all file access for Bottles. This can be done with Flatseal.
All that's needed is to create a new Bottle, then add CLIFp.exe and add the necessary arguments (play -i [ID]
).
![Screenshot of the Bottles GUI, showing several entries that are run via CLIFp.exe in a bottle called "Flashpoint-Bottle."](https://files.catbox.moe/9h4h98.png)
This also enables you to use bottles-cli. The command (when Bottles is installed as a Flatpak) goes like this:
flatpak run --command=bottles-cli com.usebottles.bottles run -b [BOTTLE_NAME] -e "/path/to/Flashpoint/CLIFp.exe" 'play -i [ID]'
Replace [BOTTLE_NAME]
with the name of the Bottle, /path/to/Flashpoint
with the path to your Flashpoint folder, and [ID]
with the Flashpoint game ID.
I may provide a video guide of my own for the future, but for now this will be it.
i thought this was fake when i saw it but after seeing it on the official channel i guess it is real
i always thought robtop didn't do ads; i guess i was wrong. colon's conclusion that this was recorded by robtop himself also seems accurate, which i guess fits in with the fact that he does everything gd-related by himself.
