how to find older no-cd cracks?

[pstuno]

I have been trying to find a no-cd for Total Soccer 2000 1.52 English Version, but I'm having no luck. I know Class released one in December '99, but it's impossible for me to find. I'm not specifically asking for a link, but rather a method for locating this file. If it is at all helpful I believe the file is named cls-totsc2k152u. I would really appreciate any help. Thanks.
