The original R1 is incompatible with and post HTL build of FSO. The patch gets around this and other errors, while creating somewhat of a visual improvement. Late testing of the patch is underway. However, during early R2 production, the INF team has chosen to discard much of the existing missions, story, ships, and weapons of R1, and create a new R1 that will be relaeased at the same time as R2. As a result, the existing R1 is obsolite as far as the future story is concerned, but its still a good campaign and a teaser for future Inferno work, which is why the team chose to patch it to work with FSO.
