Using the Adobe Flash Projector

This page will help you play RotMG with the stand-alone version of Adobe Flash Player, which is a program called “Adobe Flash Projector”. Using the flash projector to play reduces lag because Web Browsers may have performance issues with RotMG.. A video tutorial can be followed along with this post here.

Kongregate users will have to follow some additional instructions in order to play on the Flash Projector.

Please note that those who use steam to play RotMG and wish to use the standalone Adobe Flash projector must contact Deca Support to link their Steam account to a web account. Please note you will need to know the answers to the
Three Security Questions that were set for your account when prompted previously in-game.
Once you have your Steam Account linked to a Web Account, you can follow the normal steps below.

1: Download and install the Adobe Flash projector

Go to the Adobe support website and find the operating system you are using (Windows, Macintosh, or Linux), and click the “Download the Flash Player projector” link for the Operating System you are using. For Windows machines, the file needs no installation; once clicking the projector file, the projector will open. For Macintosh or Linux machines, Follow the instructions on-screen once opening the installation file to install the software.

While other Flash projectors exist, there is no guarantee that they work or are safe. If someone links you to a projector and the link is pointing anywhere other than a page on, you should not click the link and can assume they are attempting to have you install malicious software.

2: Find the current location of RotMG

For a link which auto-updates and downloads the current release, use the following:

If you use this, the only time you will have to update the URL is if the site goes down.

Alternatively, you may use a direct link to the AssembleeGameClient file; this will not auto-update, and will need to be changed with each release.

For the current release X.17.0, the link you need is:

If the SWF file doesn’t automatically download, right-click on the game, and click “Download” from the list.

If this link or the link you are currently using stops working, you need to find the new active link to the game. To do so, follow these instructions:

  • Click this link and copy the string of numbers.
  • In the following URL replace “code from previous link here” with the number string. from previous link here.swf

Kongregate users will need to copy the link into a browser and then save it as an .swf file. More often than not, simply pressing Ctrl + s will open the browser’s save window.

(On Mac the easiest method is using Lauch it and in the terminal window that opens type
wget from previous link here.swf
and the file will be downloaded to the current directory, which is usually your home directory)

As we continue, the instructions are assuming that you are using Windows, and that a SWF is saved in a folder named “RotMG” in the C: drive.

3: Point your Flash projector to the game

Open your flash projector and in the top left corner click on “File” and then “Open”.

Default (empty) Flash Projector

This will bring up a window asking you to provide either a URL or destination for a local file. Click the “Browse…” button, and select the SWF file from the “RotMG” file. The window will vary by Operating Sytem.

Press “OK” and the game should load.

Realm of the Mad God as seen in a Flash Projector

If the projector just returns to an empty white screen after pressing OK, then you either gave it an invalid or outdated SWF file. Refer back to the previous step for instructions on finding the current link.

To access the game after you close it, just reopen projector and click File to see a list of recently opened files.

That’s it! Enjoy playing Realm of the Mad God!

Kongregate users should make sure that the Flash projector is able to open the .swf file that was saved in step 2.

After bringing up the “Open” window for the Flash projector. Click “Browse”

Flash Projector "Open" Dialog Empty

Find the saved .swf and open it. You should now be able to see the file path in the “Location” box. It should look like: C:\RotMG\a.swf

Copy and paste the file path to a text document. You will be adding more to it later.

Press OK in Flash Projector to run the client.

To solve the “d’oh, this isn’t good” error: Right click in the Flash projector window and select “Global Settings”. Click in the “Advanced” tab in the window that comes up and click on “Trusted Location Settings”. Add the folder that holds the saved .swf file as a trusted location.

Restart Flash Projector and reopen the swf. It should now show the main game screen.

Getting your Kongregate Account Information

Go to and sign in to your Kongregate account.

You’ll have to get the link Kongregate uses to connect to the game. The address includes the phrase “DO_NOT_SHARE_THIS_LINK” for a reason. Anybody who has this link can log in to your Realm account, so be careful.

  • Chrome

    • Press F12 in Windows to open the developer tools console, or right click on the page and select “Inspect element”. The console should appear at the bottom of the Kongregate game page.
    • Select the tab at the top of the console titled “Sources”. You should see a box on the left (also titled “Sources”) which lists a number of site names. Near the bottom of that list “gameiframe” appears. Click on its arrow to expand it and reveal “”.
    • Expand “” and look for a line including the text: kongregate.html?DO_NOT_SHARE_THIS_LINK=1
    • Right click it and copy the link address.
  • Firefox

    • If using Firefox, Ctrl + Shift + K on Windows or Cmd + Opt + K on Mac (or right click on the page and select “Inspect element”) to pull up the developer console. Navigate to the tab at the top of the console titled “Debugger”.
    • You should see a box on the left titled “Sources”. Scroll to find “ “. A line saying “kongregate.html” should be below it.
    • Right click on “kongregate.html” and copy the link address.

    • Another method for Firefox requires Firebug.

    • When Firebug is activated, click on the “CSS” tab of the window.
    • Click on “realm-of-the-mad-god” to open that dropdown menu and scoll to the bottom and look for the line: kongregate.html?DO_NOT_SHARE_THIS_LINK=1. Click on that line.
    • Open that dropdown menu again and there should be a check next to “kongregate.html?DO_NOT_SHARE_THIS_LINK=1”
    • Right click now and choose “Copy Location”
  • Safari

    • Enable the Develop menu (under ‘Advanced’ preferences) then launch the game on Kongregate.
    • Put it in Cinematic Mode (not essential, but it makes it much easier to find the information), then right-click on the black frame of the game window and choose ‘Inspect Element’.
    • This brings up the Web Inspector with the frame highlighted. Expand three times until you see the HTML body tag. Expand that and look for and copy the HTML containing the flashvars.
    • The flashvars is the string you need to create the URL. Take it and replace all the HTML ampersands (‘&’ then ‘amp’ then ‘;’) with real ampersands (‘&’) to get the string that goes after the ‘?’ in your personal URL.

Your personal URL

Your new direct link to the game can be used in a web browser, but not the Flash Projector. It’ll look something like:

It should look like a whole jumble of data, but all you need are these and the values that come after (connected with equals signs and seprated with ampersands):


Shorten the URL to:

Test it in a web browser to see if it works.

In step 3 you should have copied the file path of the saved .swf file to a text document. It should look like so: C:\RotMG\a.swf

Replace in the shortened address above with file:///filepath here (should end in .swf)

The URL is now ready to be used in Flash Projector. It should look something like this:


You’ll probably want to save this path somewhere once you get it working, but try to keep it secure!

You have to save the path because you’re forced to paste it in every time. Windows doesn’t like the long file name.

When the game updates, you’ll have to download the new .swf and fix the path if you saved the .swf with a different name. No need to change the Kongregate account info.

If you don’t want snoops seeing your account info through the recently opened files on projector, delete all the “RecentMovie” registry entries in HKEY_CURRENT_USER\Software\Macromedia\Flash Player.

Realm in Linux

Edited from a forum post by Shalmii

Adobe does have a Flash Projector for Linux. After downloading it, unzipping the tarball, and running the Flash player program, you can come across the following error:

“Error while loading shared libraries – not found”. (the xxxxxxxxxxxxxx is just a filename )

As it turns out, the way that the 64-bit versions of Ubuntu are set up is such that the 32-bit libraries of various programs aren’t there, and are instead linked to 64-bit versions of libraries. This is all fine and good, except when a 32-bit program is programmed badly: to depend directly on the 32-bit library. Such was the case for Flash Projector.

The ia32-libs package is the one that is missing. The problem is that Ubuntu’s repositories for 64-bit distributions don’t have that package. It has similar packages, but Flash Projector demands that package.

The solution can be found on stackoverflow. Essentially, you to add the repositories for an older version of Ubuntu to the list of software sources, install the old ia32-libs package, remove the repositories, clean up, and install gcc-multilib for a few more libraries.

For an itemized tutorial:

  • Download the Linux Flash 11.2 Projector here:
  • Extract the program ‘flashplayer’ from the tarball using your preferred method
    • In the terminal:
    • cd <download location>
    • tar -zxvf <tarball filename>
  • Try running ‘flashplayer’.
    • In the terminal:
    • cd <extraction location>
    • ./flashplayer
  • If it works, great.
  • If it doesn’t work, you’re likely getting a shared libraries error. Search the library online.
  • If the library you need is part of ia32-libs, follow these instructions:

Linux Launcher Icon

To get something like this

Linux Flash Projector Icon

We’re going to have to make a .desktop file! This tutorial is for any X Window GUI interface, which covers the vast majority of normal users’ desktops.

While I’m assuming this is for Flash Projector and therefore Realm, I’m going to write in a manner that you can follow regardless of the program you’re using.

  • First, find or make an icon. You can use any image file, but .svg has the best scalability as a vector image format. .png also creates high quality icons, but they’re raster images not vector. Save this icon to /usr/share/icons. You will have to use super-user privileges, so save it somewhere else, then copy it with “sudo cp /path/to/icon /usr/share/icons”
  • Next, you’ll want to open up a text editor with super-user privileges. “sudo vi” works on nearly every system, opening up the ancient “vi” text editor. If you want something else, refer to your GUI’s manual for a sudo-like command that executes in the GUI (for the GNOME interface that I use, it’s “gksudo”, for KDE it’s “kdesu”, etc.)
  • Add the following to your file, and save it to /usr/share/applications as <name>.desktop

    [Desktop Entry]
    Name=Name of the thing that is displayed outward.
  • This block of tags is metadata telling the system how to handle the thing, where to look for the thing, and how to display itself. The thing you’re executing does not need to be a program in and of itself. You could make it link to a .jar file, or a .sh bash script to start something up in a specific manner (like Minecraft running with a custom amount of allocated RAM)

  • Next, we need to make the new .desktop file executable. Do “sudo chmod +x /usr/share/applications/<name>.desktop” to add this property to the launcher.
  • That should be all you’d need to do. You can copy it to other locations (like ~/Desktop) to put it there.

Here’s what my launcher for Realm looks like:

[Desktop Entry]
Name=Realm of the Mad God

This links to an icon of Oryx (the .png), and a simple bash script (the .sh)

cd $(dirname "$0")

which opens up Flash Player (also in the /opt directory), grabs the latest AGC from Realmeye, and runs it.

Tips for playing

When you use Flash Projector in Windows, press Ctrl + Alt + Del (Ctrl + Shift + Esc in Windows 7) to open task manager, and set the priority of the projector to High. This should reduce lagspikes.

You can also use Flash Projector to see a bit more of the game at a time:

  • Open the game in Adobe Flash Projector
  • Make sure hardware acceleration is off
  • Set the zoom level to 100%
  • Set Flash Projector to display in full screen

This will allow you to see objects that are just slightly outside of the normal view.
