From FE4 and FE9; it’s an item that grants the holder mounted re-movement now ported to FE7
Have a demonstrative video
The patch is here
The patch puts the hack at 0xD70000 and the byte at 0xD7001A determines the ID of the item you want to grant removement
If you want the hack somewhere else, follow these instructions
In this .dmp, change the last four bytes to the pointer of where you want to put the hack + 1 and paste write that to 0x1CBA8
00 4B 18 47 01 00 D7 08
Then paste this .dmp to the offset you want and change the value 0x1A bytes in to the ID of the item you want to be the knight ring
