The high-resolution cutscenes, or more specifically the recreated cutscenes, are an option available in the installation; these do not require Jaded's pack. These are the options emphasized:
- Freespace Upgrade MediaVPs
- FS Port MediaVPs
- MjnMixael's Mainhalls
- HD Hud
- Jaded's HD Radar Icons
- Lafiel's RadarIcon Script
- Admiral MS' ScreenCam Script
The standard Silent Threat: Reborn installation already includes the first four of these, so it really depends on whether you want to use the last three. Jaded's pack does not modify the missions or the difficulty level. However, keep in mind that ST:R *is* a little more difficult than either FS1 or FS2.
