The update also improves backwards compatibility with older PlayStation 2 (PS2) titles for the units with emulation support for those games. The newer 40GB model does not support the older game titles. Firmware 2.0 also introduced a feature to remotely start up a PS3 over the internet via a PlayStation Portable (PSP) handheld console.
The update has made changes to this feature after many users reported that it was not reliable.
