TSF is supposed to have JJ2 built in, but I seem to recall that varied between publishers. In any case, I'm surprised it doesn't at least have the shareware episode, as even HH98 did that. (I would ask where you got these games, but somehow I already know.)
You should be able to play the shareware episode in TSF by moving all the shareware files into your TSF folder, and saying "no" to any overwriting it asks you about. I don't think 1.00g is compatible with anything, though, so you'd have to actually buy the game.
