*Flash3 - Used on development kits in firmware 5.00 and later to store kbooti.bin, kbooti is copied from flash3 to 0xBFE00000 (tachsm) by bootdispi.bin, about 1 MiB in size, It is used on retail units to store vsh specific applications such as 1seg. In custom firmwares it can be used along with flash2 to redirect firmware elements such as fonts. Also contains the Premium XMB Theme which is exclusively available on the MHP3rd PSP 3000 models. | *Flash3 - Used on development kits in firmware 5.00 and later to store kbooti.bin, kbooti is copied from flash3 to 0xBFE00000 (tachsm) by bootdispi.bin, about 1 MiB in size, It is used on retail units to store vsh specific applications such as 1seg.
