usbloadergx/source/usbloader/disc.c
giantpune dd4704cce3 * brought back the return-to patch complete with settings and shit to click on 
* in the global settings you can select any 0x10001 title that is actually installed in the nand.  in the game settings, you can decide whether or not to use the global setting for that 1 game.
