[TUTORIAL] Remove display sleep

First you need PSVita Registry Editor:

https://github.com/some1psv/RegistryEditor/releases

Backup your vd0:\registry folder via FTP

Install Registry editor then navigate into CONFIG\POWER_SAVING\ and change suspend_interval value to 0.

Reboot.

It's useful while dumping big games.

Take note that on OLED PSV it can cause some burn in on the display if it stays on for long times.
