NOTE: You will need to setup a Linux terminal on your Intel based Chromebook. For more help please take a look at the official documentation at https://chromeos.dev/en/linux/setup
Open up the Linux terminal and navigate to your home directory. Once there we will
make sure to perform a system update and install wine and the mesa drivers
cd ~/
sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y
sudo apt install wine wine64 wine32 libgl1-mesa-dri
Create a wine32 prefix folder since The Realm is an older game
mkdir ~/.wine32
WINEARCH=win32 WINEPREFIX=~/.wine32 winecfg
Grab the latest version of the winetricks script and make it executable
and then use winetricks to install Microsoft .NET 4.0
wget https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks
chmod +x winetricks
WINEPREFIX=~/.wine32 ./winetricks dotnet40
Go to https://realmonline.com and downloand the TheRealmOnline.msi setup
file in Chrome OS and copy it to your Linux Files folder via
the File Manager.
Once it's copied over go back to your Linux terminal and install the
TheRealmOnline.msi setup file using wine
WINEPREFIX=~/.wine32 wine msiexec /i TheRealmOnline.msi
Now that everything is installed we will set up a script to launch the application from the terminal to make sure it launches correctly. Trying to launch it via the App Launcher will cause the game to crash.
echo "WINEPREFIX=~/.wine32 wine ~/.wine32/drive_c/'Program Files'/'Rat Labs'/'The Realm Online'/launcher.exe" > realm
chmod a+x realm
Launch the game from the terminal
./realm
