This application allows you to create and edit gametype files. Simply said.
Application and document icons were awesomely designed by TaxiService. I thank beta testers such as 002, Modzy, Hostbot, Taxi, and to anyone who I may have forgotten.
Info about using gametypes can be found on HDM.
This program will only work with Halo Demo gametype files, not Full ones unless you happen to be on a PPC or if you're running the non-UB version of full.
Mac OS X 10.5 or later is needed.

(For programmers, source code is available here.)
[EDIT]: This software does not work for HaloMD and is no longer supported. For educational purposes, someone can try to update it to work with Full/MD - it is a matter of byte order differences and lots of testing. Removing the deprecated garbage collection would be a good idea as well in favor for ARC or manual reference counting.
