mastercore v3

A Smash4 resource provided by @dantarion

what is mastercore?

mastercore is a online resource that contains information about Super Smash Brothers for WiiU. Nintendo has decided to do incremental patches to the game over its lifetime, but they don't provide patch logs that tell what is changed. I, @dantarion decided to reverse engineer the game and create automated raw diffs of the patched files.

This information is presented in its rawest form. If you want easy to read patch notes, your best bet is to check out this community forum post on SmashBoards. Otherwise, if you want an inside look into how this game is put together, and if you want to add things to said forum post, this is the place to go to look for info.


Here you can find updated sets of diffs that show changes from one patch to another.

1.0.9 -> 1.1.0 ACMD 1.0.9 -> 1.1.0 PARAM 1.1.0 -> 1.1.1 ACMD


Here you can full dumps of the characters scripts. You can use these to lookup hitbox properties, framedata, etc.

v0 v32 v48 v80 v128 1.1.0 -v144 1.1.1 -v160
