Opera Mini can also be used on PSP through PSPKVM, a homebrew application which is a Sun Java Virtual Machine.The version 2.50 upgrade added Unicode (UTF-8) character encoding and Auto-Select as options in the browser's encoding menu, and also introduced the saving of input history for online forms.Version 2.70 of the PSP's system software introduced basic Flash capabilities to the browser.On the PSP console, the XMB had top level icons for Photos, Music, Videos, Games, Networking (which allows the use of the web browser), Settings and Extras. With the PSP, using the Home button while playing music would allow users to browse photos without stopping the music.While XMB proved to be a successful user interface for Sony products such as PSP and PS3, the next generation Sony video game consoles such as the Play Station 4 and the Play Station Vita no longer use this user interface.
