Whdload need 512MB to rekick so you can expect that all games that require less than 1,5GB to run ( almost of 1 and 2-disk games)
if the 2nd floppy wasn't full, you can expect the game to run (if whdload doesn't require FAST RAM).
I can tell that more than 300 famous games should works.
There's a way to know the list but I can't tell it. (sorry)
