Hello. I have the Mac version of Jazz JackRabbit 2 (v.1.2.8) and I hear that the levels that pc user's make still work for Mac. I downloaded Blades Battle Pack but once I download them I get a Folder with a bunch of files named this
AztecBattle.j2l

BetonBattle.j2l

Where do I put this stuff? In my JJ2 folder I have....(f means folder.)
f Cache
f Data
Jazz Jackrabbit 2™ Application v1.2.8
f Jazz Manual
f Movies
f Music
f Plugs
f Tiles
And some saved games and Logfiles.

I will appreciate any help on installing custom levels.
