Instructions
Verify that your edition of "KH: BSS" has multiple translations. Only the European and collector's editions have this feature. The version will be indicated on the packaging or, if you downloaded the game from the PlayStation network, on the receipt.
Turn on the PSP. If your copy of "KH: BBS" is in UMD format, take it out of the PSP's UMD drive before turning the unit on.
Press the "Left" arrow button after the PSP's menu screen loads, or push the joystick left to scroll through the menu until the "Settings" icon is highlighted. Press the "X" button to enter the "Settings" menu.
Press the "Down" arrow button or push the joystick downward until the "System Settings" menu item is highlighted. Press the "X" button to enter the "System Settings" menu.
Scroll down until the "System Language" menu option is highlighted. Press "X" to enter the "System Language" screen.
Scroll up or down to highlight the language you want use. Press "X" to select the language. Your PSP's default language will be changed to the one you selected. "Kingdom Heart: Birth by Sleep" will now use that language during game play.
Insert the "KH: BBS" UMD into the PSP's UMD drive or, if you downloaded the game, open it from the PSP's "Game" menu to play the game. The PSP's default language can be changed at any time by following the procedure described above.
