(Episodes 2-4 version)
 

I use to have a version of Jazz Jackrabbit 1 with episodes 2-4. It came on cd but had episodes 2-4 instead of episodes 1-9. It didn't have episodes 1 and 5-9 on it. The cd and everything looked looked entirely legit. I thought it was a normal version then I looked it up recently and apparently the game was released with various different episode sets but It didn't say anything about this particular one.

So it's actually a legit version of the game.

Well... I don't actually have a physical (or even digital) copy of the release, so I'm just speculating based on the box, but I kind of doubt it. It was released by B&N Software, whom I don't know from Adam, and it looks like they didn't have access to any official Jazz artwork, including the logo. That feels suspicious to me, but I could certainly be wrong.

I thought it had all the levels from Jazz CD. It looks like the regular cd version on the box. It didn't have the word CD in the game. I thought it was the 9 episode set.
