=History=
The original build of the Oni application (v1.1; 1.5MB) was compiled by Bungie for the PowerPC processor that Macs were using at the time. However, it was also a Carbon app, meaning it was written primarily for Mac OS 9 with only basic compatibility with OS X. Mac OS X was not even released until a couple of months later, and making it a proper Cocoa app would have required rewriting it from the ground up in Objective-C.
 
With Bungie's permission, Omni Group [http://www.omnigroup.com/mailman/archive/omni-press/2001/000008.html released] a free Cocoa port by the end of the year (v1.0 (Mac OS X), version 1.36; 4.6MB). This port allowed Macs running OS X to run Oni with fewer hiccups in terms of compatibility (such as flawed controls), making the port more of a convenience than a necessity. It did, however, guarantee the game a longer playable lifetime in that it updated the app to more modern technology on the software side. No one could have known at the time that Apple would later switch to Intel processors, moving away from the PowerPC chip that Oni was written for.
 
Omni's port is therefore native for modern Macintoshes' software in that it is a Cocoa app, but non-native for modern Macs' hardware in that is is written for the PowerPC chip. Additionally, various other elements of the OS and hardware have changed over the years, making the Omni port unable to run on modern Macs without some modifications. Through the efforts of the Oni community, various hex edits have been devised as ways to not only allow the application to run under the latest versions of OS X, but to extend the potential for Oni modding.

The changelog lists all above changes, further experimental ones, and also records which functions and variables were replaced in order to add the new ones.


Known Issues

  • While playing in Windowed mode, the game and computer cursor are not synced, so one can click outside the game window and disrupt the game. Workaround: set the game resolution to the display resolution (or as close as possible) to minimize the disruption.
  • In Dev Mode, the numpad number keys 0-9 are not accessible. Thus the default NumPad keys to move the camera will not work. Workaround: in the key_config.txt file, bind other keys to the camera commands.
  • In Dev Mode, when entering commands in the console (accessed with the tilde (~) key), the Shift key will not work with the letters a-z, therefore commands requiring uppercase letters cannot be entered. No known workaround while using the console, but the commands that require uppercase letters can be run by entering them in BSL scripts.
