dimok321 1913aea194 *Added custom Game Categories switchable in main menu and selected/adjustable in game settings menu. Own categories can be added and applied to games. A multiple category selection is supported in showing and assigning.
*Fix homebrew browser indicator counter (thx dj_skual)
*Fix We Dare anti piracy protection (thx oggzee)
*Fix Wip patching
*IOS reload block working with d2x v6 beta1+ with all filesystems
*Changed CheckBox Cross to squareroot sign
*Added auto detection of the usb port on start with Hermes cIOS (allowing startup without waiting 20s for USB port 1) (was build in in rodries ehcmodule, thx!)
*With new d2x v6 beta1+ sector sizes other than 512 bytes per sector should be supported on ext/ntfs (maybe fat too) (NOT TESTED, need feedback)
