With no major reports from users since it’s release, firmware 3.30 is safely in the wild. Here is a rundown of all the new features:
Trophy enhancements –- Now you can more easily sort trophies in the [Trophy Collection] and [Comparing Trophy] sections. Sorting can be done with [Trophy Collection] in the [Game Category] and also when comparing trophies with your friends in the [Friend Category]
Trophy Folder (Title List) can be sorted by game name/ by title according to the date in which you earned your last trophy (ascending/descending)
Add-on list (Group list) can be sorted by original/the date in which you earned your last trophy (ascending/descending)
Trophy list can be sorted by original/trophy name/grade/date of obtaining the trophy (ascending/descending)
3D Support – System prepped for stereoscopic gaming
Now for a few not so obvious ones, as the sixthaxis noted below:
BD Audio Output Settings Direct and Bitstream
Direct – Set to output audio with the original digital signal prioritized.
Mix – Set to output audio that is first mixed with sound effects such as button sounds and then converted to bitstream format.
PC Remote Play – Arriving on set VAIO PC’s, users will be able to register a PC as a remote play device.
