After 3 and some change years (6.60 was released on August 10, 2011) the PSP long since hacked into tiny pieces has gotten a new firmware update. Currently only released in Japan, no word on when or if it will arrive elsewhere. You gotta love that word "stability".
JP Playstation.com said:For PSP® system software version 6.61 update
From January 15, 2015, I was to start the update of the system software version 6.61.
The main features that are updated in the system software version 6.61
- Use or non-formal update data to offer in our network or via UMD®, so you do not update other than how to inform the Company, please note. If you have made an update of the body function in the wrong state, not only does not perform the operation guarantee, and will be covered by the repair and warranty. In addition, there are cases where formal update is not available.
- System software update, please do not take place in the vicinity of the power outage time.
- In the system software, I have to improve the stability of behavior.
EDIT: Changelog added. Please note this is google chrome translated english so it's batshit crazy.
