Yah I dont keep my roms zipped either, I don't see the point, but than I come across people that have thousands of NES roms, and if you zip each one individually you might be able to save a couple hundred megs, than I see that.
And yah, I haven't updated Jnes in about a year or two, i guess it's discontinued in that sense, but I never publically said it would never be updated again, which would be a more thorough definition of discontinued I suppose. Thanks for stopping in!
