*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)
