Thanks, that’s software I can find.
But it seems to be abandoned. The last release is from January 2016, and the GitHub project was archived over a year ago.
So it seems that this project is pretty dead and won’t ever be updated to work with any remotely modern PHP version.
Also, it seems to be the final project in Softaculous in the gaming category, which suggests to me that there might not be an alternative to this software.
I don’t know what this software is supposed to do, but maybe you can approximate the functionality using more generic software.
