So many different files and versions floating around..
I hope this helps a bit:

 MAZESPX    MAZE saver extension.

 MORESPX    LIFE and WORMS saver extensions.

 NEWSPXS    DRAGON and SOLIDS saver extensions.

 SCRPE12    Screen Peace v1.2 program + BITMAP, BLOCKS, FLEX,
            KALSCOPE, SNOW, and STICKS saver extensions.

 SHF11SPX   SHUFFLER saver extension.  Like PUZZLE saver but
            some additional bells and whistles.

 SPEXTN     Saver extension "toolkit" (SET:-).  Source code
            for STICKS saver extension.  This is pretty useless
            w/o Windows SDK, but if you're curious...

 SPX2       New versions of AQUARIUM, EYES, FADE, FIRE, FLASH,
            KLOK (used to be CLOCK), PUZZLE, SPACE, SPHERES,
            and WALL saver extensions.

 These should be the newest versions currently (April 4) out there.
(And if they aren't or something's missing it'd be extremely kind
of you to upload it here or at least notify me.)
