A Link to the Past SNES Item Hacking

Hi,

I'm relatively new to the Zelda ALttP hacking scene, and I want to know if anyone has a list of ways in which you can change the properties of items handy. I've already looked through this https://www.zeldix.net/t676-stronger-sword-beam forum post which goes into detail about how to change the properties of swords. What I want to know is what bytes change one property of an item into another. Obviously, nobody has a complete list handy, but I think that even a partial list would help the modding community.

i listed some of the hex addresses on that forum. as for changing the properties such as removing the invincibility from the cane of byrna, well then that requires asm. hopefully there will be an item editor released, but some items such as the cane of somaria will be extremely difficult to edit because the block is a sprite.
