.mkv files are container files for videos, and as such, should be played with an appropriate video playing application. What you downloaded isn't the game but a series of videos showing someone playing the Toaru Kagaku no Railgun PSP game with subtitles added. It is basically a video walkthrough of the game or a Let's Play series.

Those videos were in Niconico until a bunch of people requested js06 to translate them and were later uploaded by him onto the Internet and was later uploaded by Ultranova in turn.

If you want to download the game then use this (and I'm assuming you know how to torrent): http://www.nyaa.se/?page=torrentinfo&tid=266155
