This particular bundle had almost everything - the original 6 disk episodes, the 3 CD episodes, and even Holiday Hare '94... but not Holiday Hare '95, for some reason.

I know '95 was never folded into the main game the way '94 was, and you're supposed to be given an option to play '95 upon booting the game, but I'm not even being given THAT here... must be a feature exclusive to the GoG rerelease, which isn't this one (though it does incorporate some patches from it), so I'm having to grab '95 separately.
