Is it possible to inject a special from one character to another?
It depends on the Special.
Character doesn't not have enough specials
- How to add new specials with hex edit?
Adding Special Actions isn't entirely possible yet. Pikazz managed to do it, but it's very buggy.
and here is the other thing:
- How to edit Floating points so that the injected specials work as the Owner of that special
That is not possible at the moment.
Fox has Ike's Side B and all it's attributes (Floating Points, charge frames, etc
You can use various PSA commands and Float Variables for a pseudo Ike Side Special.
