Right, I just had a bit of a deeper look, the sl3. refers to which save slot the save appears in, simple...
I loaded it up and it works fine with the newer 100 levels (which I now need to complete!)
I checked the other dirs on the disc and have found 4 files called CLOCKCD1.LVL - CLOCKCD4.LVL, these don't seem to be needed to run the game.
I've also found an ASM file on the disc called conv.asm and after a brief Hex view says something about "25 per pack".
I presume this ASM file is for converting the 4 LVL files (25 per file) into the sl3.potpouri file I uploaded earlier.
In case these are useful to you I've attached them to this post.
