Sony pulled the software update from the PSN after numerous users complained they could not access the adhoc play feature in PSP games after installing it.
Thankfully for customers, Sony responded to the complaints quickly and pulled the update before it affected more users.
And thankfully for Sony itself, the update is largely a matter of housekeeping and minor system adjustments so it won't likely face a huge consumer demand.
As it stands, v1.65 aims to address the following issues:
- A Notification Alert option will be added to Settings, so you can toggle alerts on or off
- 'After 10 minutes' will be added to the time options under Power Save Settings
- An Arrow icon will now appear when PS Vita finds new activities in the LiveArea
- Caps Lock will be supported in the On Screen Keyboard
With any luck, after Sony irons out the kinks and makes the v1.65 update live again they will begin working on a way to make PSone classics playable on the Vita.
