Public Service Announcement:
I was having a weird issue with my XStation. It wouldn't pick the right game. Like... I would pick a game, and a different game would boot. This happened with almost every game, and it was always the same wrong game (often off by one entry). So, after a bunch of looking and finally realizing I should just check the issues section of the Github, I realized that it was likely a partial file or something from a failed unzip.
It was actually worse in some ways, because I think it's going to be something others will see. The pre-patched version of Policenauts you're likely to find out there (Archive dot org) has an M3U file stuck in it that emulators apparently use to find where the cutscenes are or something. The problem is that the XStation doesn't know what that is, but knows it's a media file, so IT THINKS IT'S ANOTHER GAME, and fucks up the list. So, yeah, if you get an XStation, delete that file from your Policenauts, if you download it from somewhere. Save yourself having to look through 700-ish folders to find the offending file.
