If your Chromebook supports Linux apps, enable “Linux (beta)” in the Settings app. After that, it should install some packages you need to run Linux apps. Then, do as in regular Linux:
Just unzip the file and you’ll find an x86_64 file in it. Look at its Properties and Permissions and make it executable. Put the file in any location you want, then open the terminal and go to the folder where the file is located and run:
./OmegaUpdater.x86_64That’ll run the updater, and it’ll create some other files in that folder. One of those files is ‘YGO Omega.x86_64’ (without quotation marks). But the terminal will tell you that you can’t run the game. That’s because that file isn’t executable yet, so just look at its properties and make it executable. Then, like the other file, open the terminal and run:
./‘YGO Omega.x86_64’
