PS3 4.20 Firmware Now Available; Hidden Features Revealed
A new firmware for the PS3 has been released today by Sony that is supposed to “improve sidetone audio performance (for the Wireless Stereo Headset) by giving you the option to select one out of five levels for microphone audio, or turn the feature off completely. For those of you who use the Wireless Stereo Headset to watch Blu-ray or DVD movies on your PS3, this system software update will also enable virtual surround sound functionality, giving you a superior audio experience.”
In addition, another added feature of the new firmware allows everyone to copy multiple save files and upload them on the PS Plus online storage all at the same time. Also if you’re using the Auto Off feature of the PS3, more customization can be done.
To download the firmware and apply the new features, simply head over to the System Update option from your XMB.
