.tar.bz2 is a compressed, archive format. Similar to .zip, or .rar.
So first you'll need to extract/decompress the archive.
To do this, open a terminal and use the
cd
command to navigate to your Downloads directory (or wherever you downloaded the file to. Then use the tar command to decompress the file
e.g.
Bash:
cd Downloads
tar -xvf DatingStartVN-1.0.2-linux.tar.bz2
That will probably end up creating a directory called
DatingStartVN-1.0.2-linux/
.
cd into that directory and there will probably be a shellscript or some other launcher/installer file.
Once you have found a launcher/shellscript, make sure it has executable permissions:
e.g.
Bash:
chmod +x nameoflauncher.sh
Where
nameoflauncher.sh
is the name of the shellscript/launcher.
Then you should be able to run the script/program/launcher.
Run the script in the terminal and see what output it gives.
If you're lucky - the game should start. If not - the error messages should give you some idea of what things might be needed.
For example, if this is a python based game, you might need to install some additional python libraries in order for it to run properly.
If the game is not pre-built and it's only in source form - you may have to compile/build the game. But let's not get ahead of ourselves. We can tackle that later, if need be.
The first step is to decompress the archive and see what it contains.
Then make sure that any launcher scripts, or binaries have executable permissions. Then run it in the terminal to see if it runs, or displays any error messages.
If it runs - great!
If it doesn't, and it throws a bunch of errors and you are unsure what to do next:
Then add a reply in this thread, with any error messages that are displayed in the terminal when you run the script/program.
EDIT -
BTW - Once you have got the game working properly, you should be able to launch it from your GUI/file manager.
The reason I'm getting you to run it in the terminal at first is because it's going to be the only way to see any error messages/information from the game if it goes wrong!
