In the beginning, however, the PC port suffered many problems. When the contract programmers received the FF7 source code from Square, it was a horrible state of atrophy. When work started on the port, it was soon discovered that they had received an earlier, buggy version of the program. Work had to stop while Square accumulated a later version. It was also discovered that the people and equipment used to create the backgrounds for FF7, were now being used for FF8 and FF9. There was no way to re-render the backgrounds and the port team was forced to use the original low color/low resolution PSX dependencies. The movies faired worse. Squaresoft never rendered high resolution versions of the movies. The movie format was incompatible with Microsoft's DirectX system, so it was decided to convert the compressed PSX movies to one more native to a PC platform. This caused disastrous results. The movies were now a copy of a copy of a low resolution render.
