You know, something I could put the files into and then click on the package to play the game? Preferably, something that doesn't take up 200MB of extra space on the hard drive. I just want to be able to put the game in a package/wrapper so that I don't have a dozen or so files laying around in one folder/directory. I already have Rosetta and the games run fine.
Heretic II and RTCW (the copies I have, anyway) are OS X games, not Classic Mac OS.
