It's not overly useful but in little king's story I found the address of a person who is in my party and I worked out they are all 0x18B8 apart so from this I can instantly find each address of every person.
Its very basic but beats adding a value in calculator together 100 times.
Probably more useful to those who create codes in wiird and want to double check offsets are correct
just uploaded a slightly newer version that has some error checking etc
Also an opportunity to build apps in Visual Studio and learn more
I can already think of a great use for this, my Brawl items description edit stuff since that's also about a hundred adresses
