LOST TI NSPIRE CX CAS SOFTWARE LICENSE CODE

The source code was originally released under a proprietary license which prohibited commercial use and did not require programmers to provide the source code for the modifications they released in executable form. The original purpose of source ports was cross-platform compatibility, but shortly after the release of the source code, programmers were correcting old, unaddressed Doom bugs and deficiencies in their own source ports, and later began adding new features to alter gameplay. By abstracting away the x86-specific code, ports have also been created for a large variety of other hardware platforms: PowerPC/ Macintosh the Game Park 32, a Korean hand-held the Nokia 76 cell phones the Sega Dreamcast and any POSIX environment with the X windowing system. Source ports have been created for a variety of PC operating systems, such as the 32-bit Windows family, Linux and the BSDs. The term itself originates from the first source port, DOSDoom and its 0.2 version. Hence the term 'source port', which out of custom also is used for those modifications which are not technically ports to another platform.

Although Doom was originally created for DOS, the release was of the Linux version, and the source code had to be ported back to DOS and to other operating systems.

The Doom source code was released to the public on December 23, 1997. The term usually denotes a modification made by fans, as opposed to any of the officially licensed versions produced by id Software or affiliated companies. A source port is a port of the source code for the Doom engine.
