Everything you described sounds about right. If you just double click the scripts, the command line window will auto close after running it. If you want to make sure the output is correct for them, try opening a command line or powershell window or some Python editor window like IDLE separately, then run the scripts from there. But so far only a few of the bosses have their combat dialog translated, and the location names are images so I haven't looked into editing them yet, so that is to be expected. I'm currently working on translating the rest of the bosses
