A lot
Including that this script has been made on
request by me, and I've never heard of "xPSM".
Open both PLSC file in WinZIP or an equal utility, and you'll find a couple of things in xPSM, which are not in my script:
- A DLL, named "functiones",
- notify.mp3, I don't use sound files,
- Conf.ini, I don't use settings in this script (yet, and they'll be stored in the registry)
If you see the way both scripts are programmed, mine is very different.
And there are tonnes of "countdown-in-PSM" scripts as well.
