Step 1: Software and Stuff
USBxtafgui v4.4 (for extracting the save files)
Hxd (for hex editing/modding the files)
360Revolution (for rehashing/resigning the files)
Note: the 360Revolution tool can be used in place of USBatfgui v4.4
USB stick/flash drive
An Xbox 360
Step 2: Prepping the File(s)
Step 3: On the Computer Side Pt. 1 Loading the Files
Step 4: On the Computer Side Pt. 2 Hex Modding
Say you want the sanguine rose and you put in an iron dagger, you would find the iron dagger ID (remember its only 5 digits) then exchange it with this code 1CB36. That gives you the sanguine rose. You can quickly find an ID by pressing the control key and the F3 key.
If you want say 250 sanguine rose then, you would need to find the text to hex converter from swing note. (Assuming swing note uses unsigned long data types). Type in 250 in the text box then press the enter key. You should get 323530 replace that with the numbers directly after the sanguine rose's ID and you should get 250 sanguine rose.
*New Method to swing note*
Inside hex workshop there is a tool called base converter open it (its the little gear looking thing). Then switch the first drop down menu to intel. Next the second drop down must be an unsigned long data type. Change the non hex value to 250 then you should get a new number in the hex field if it is the same as the swing note number then be free to choose which tool to use. If not however then use the base converter number as it would then be the correct number to use. Swap out the item quantity by copying the new hex number then highlight the old quantity value. Then right clicking where it goes right after the item ID and use the paste insert function to replace the numbers.
