usbloadergx/source/prompts/filebrowser.cpp
lustar.mii 51459465bc Added more alt-dol selection prompts for known games that require different settings to access all the content. 
All options pages now contain the correct number of lines, which together with another adjustment should fix scrollbar alignment (issue 971).
Added missing scrollbar on custom paths page.
dimok fixed the file browser bug that prevented going back to the parent folder if the current folder was empty (issue 836).
Fixed parental control keyboard bug introduced in r750 (issue 976).
The free space text is now in correct order when the GUI is set to Japanese.
