"Q. Does SWGEmu use any of Sony Online Entertainment's code?
A. The absolute and short answer is no. Every bit of code developed at the SWGEmu project has been written from scratch by freelance developer's committing their time and effort to the SWGEmu project without the benefit of financial gain.
Q. Has SWGEmu ever seen Sony Online Entertainment's code?
A. Absolutely not. In fact, Sony Online Entertainment persists that they have lost the code entirely. Not only does this make it impossible for SWGEmu to utilize the code as reference if Sony Online Entertainment was kind enough to grant permission to do so, but it makes it impossible for Sony Online Entertainment to release classic Pre-CU servers to rival what SWGEmu aims to accomplish.
Q. How does SWGEmu develop the software without Sony Online Entertainment's code?
A. SWGEmu's software is written through a process known as Reverse Engineering. By applying the Scientific Method, SWGEmu's developers observe game-play, and then attempt to recreate it's experience through programming"
They developed the game from scratch!
Can we move this tread to the private servers tread?
