You're a little too late, Feline. As the games were just simple platformers released in the 90's, the projects were abandoned after the first few years. As a note, I got JJ2 and JJ1 for 4.95 CDN at a grocery store. That is not a joke.

Now that it's been a few years, I got TSF from an "Old Dos Games" site that pays for each download with ad support. In other words, it's practically freeware, or otherwise known as "abandonware". Unless somebody wants to buy the original packaging for collector's purposes, they probably shouldn't.

On that note, even if you're not going to play them, I suggest you keep them. Somebody may give a pretty penny for such collector's items.
