Back in the day I used to own this game, lost it and now have the GOG version. Back in the day I also modified the game. In there is a .cvs file (can be opened with Excel) that holds some of the games values, I can change them to cheat, or add new items to the game.

What I need to know is how to open these .smk files and extract the contents to modify some the files?


Edit: Oops looks like it was Civ City game that I'm thinking of. Nevermind.

Just in case someone's still interested, those are video files you should be able to open with the player provided for download there:

Linux users can read these videos with mplayer/mplayer2/mpv.
