Yo people still want infinite shields? I found a way for that ages ago. (sorry Ive been out at sea for a while because I'm in the Navy so I don't get to use the internet as often to keep up w/ smashboards)
Uuugh, I don't feel like crackin out the lappy but those pics I posted with offsets for the Common file is where all the shield stuff is. You'll want to give Shields a billion HP or whatever, or just make it so they recharge at a super fast rate. Pretty simple. On a separate note, I posted a pic of where the offsets are for shield Data in the common file (this works for everyone but Yoshi) so you can just zero out the part where it calculates the change in shield or whatever else and it will get rid of shield Damage.
You can also do fun stuff like Make shields HUGE ... like it covers the whole screen in a color lol, you can make it to where shielding an attack KOs you from shield knockback being ridiculous, you can make it to where shields start small and get larger.
I actually have a request for you IE, do you know where the gravity for Ice freezing is? Because I'd like to make Roy go from a fire char to an ice char but Ice moves are crap since you float and spin instead of just falling.
