just curious what file makes the background when in usb mode and when viewing saved game data on the psp change each month? any way to hack this file to only display one certain color all year? (like black as an example). since i don't have 2.0 firmware on my psp and my homies don't have 2.0 does this change after updating since the custom background feature was added? i really wish there was a way other than the illegal sdk and devkit to view what each of the files in the bios do so we could further mod the official os for 1.0 and 1.5 users.
