usbloadergx/source/libntfs/volume.h
dimok321 64f8406b07 *Mem2 fix 
*updated libntfs (write fix)
*updated libfat
*lots of changes in the startup code, removed almost everything. This might cause problems for some drives at loading the gamelist and needs to be adjusted later but better this time. more cleanup is needed in main.cpp and will come.
*using libogc sd/usb for config loading and reload to cIOS afterwards
*added missing boothomebrew stuff pune forgot

NOTE: From now on we will be doing a lot of revs which we won't be compiling and releasing. This revs are officially not available for public so don't making issues regarding those revs. Those will be closed right away. We need first to cleanup a lot of crap and update loader to new standards before releasing stuff again.
