There are 2 kinds of mega memory cards for the Sony PlayStation. One is called "compressed memory" and the second "non-compressed". The first one (compressed memory) causes a lot of problems with certain games: you can lose data because of the software inside which compresses the information to be stored. The second one, non compressed, is the same technology that Sony TM uses.
