Updating software on psp
You can also convert your old PS1 games and play them your PSP.All PS1 games are supported, not just games on the PSN.
Note: On the 15/01/2015 Sony released PSP firmware 6.61, some three and a half years after the last 6.60 update.
When custom firmware is on your PSP you can use emulators, homebrew applications and even backup your games to the memory stick.
This allows you to easily carry around more than one game, and helps to save your PSP's battery as it does not need to power the UMD drive when playing games.
If the firmware is permanently installed it means your PSP will boot directly in to the custom firmware when powered on, if not it means you will have to enable it again by launching a simple app.
This however only needs doing from a cold boot, if you leave the PSP in standby like most people do (you probably do this without realising) then you will not need to enable it.
