If you're looking for a great Windows remake that keeps the original style, check out Megaplex. Apparently the original website is gone, but archive has it as well:

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

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.
