The Megaton firmware has finally arrived, and all you need to do to obtain it is to access the Network Update and download the file. Some of the expected updates include changes such as the addition of Remote Play under Network, the inclusion Online Instruction Manuals, timed recording, a visual player as well as 3-speed fast forward and fast reverse.
Those who are unfortunate enough not to have WiFi access can download the file manually and connect your PSP via USB. Head on to the PSP/GAME folder, create an “UPDATE” folder and place the EBOOT file there. In closing, you must access your Memory Stick’s games, and choose the update from there.
