In idlemaster there is an option to exclude games. Also by the way how do you get it to work man? Since I have helped you is there anyway you can help me?

https://www.youtube.com/watch?v=r-jeMjxrorM this video is for ubuntu users, open the terminal (default ctrl + alt + t) copy the code on the description of the video to the terminal and press "enter", then the terminal will ask for your password. ubuntu has one security config that don't lets you see if you are writing the password; just write it and press "enter" again, the terminal will ask for install some packages (you just have to put if yes or no y/n). then the terminal will begin to install the plugins needed and in some minutes it will be ok. then when you installed the plugins close the terminal and open a new one, write "python2" (leave a space) grab the "start.py" file on the linux archive and leave it on the terminal and press "enter", it should show now the route of the archive. then you just push enter and it will run on the terminal. for more detailed information see the video; i'm asking how to use the blacklist because linux don't has a graphical interface, i googled how to use it hours ago and now i know what to do, if you need another help just ask me, the only problem i have now is how to know the ID of a game that i can't install.

I'll try this in a bit, I'll tell you how it goes, thankyou very much regardless man =)
