exactly! just make sure to add a 0 to the beginning before inserting in little endian format
again, for example, 800 is 366 in hexadecimal. we add a 0 to the beginning to get 0366. and then we break it in half to get 03 66. finally, we switch these two around, and then insert that (66 03)
and HxD is the best, good job~
