The first program is called Brain Builder 3.0. It's a little old which is why it's freeware. Download size 29 MB. The 2nd is my favorite, Captians Log (mere 10 MB) in case you need to remember directions or basic math. It's old, runs in MS-DOS from 1999. Found it on an abandonware site. I had some fun with Brain Builder...it told me how much my memory is average.....

Google "KGB compression" and I'm sure you'll find something that'll open it.
