If you really want to play those games, I recommend you install Rocks and Diamonds, which implements Supaplex, Boulder Dash, Emerald Mine and Sokoban and even has some additional content. It's open source:

There are versions for Windows, Linux, Mac.

Supaplex is even on Steam, but probably not linked to the original creators, which have declared the game as freeware.
