Welcome! This is an unofficial page for the Super Smash Bros. Melee mod called SD Remix. This page was made to serve as a quick one-stop shop for information on the game, as well as guides on how to play it.
SD Remix is a modified version of Super Smash Bros. Melee that rebalances the cast. This is done primarily through buffs. No characters are nerfed in this version of the game. Instead, the strongest characters are left unchanged while weaker members of the cast are buffed accordingly.
It might be easier to say who wasn't changed:
Fox, Falco, Marth, Sheik, Jigglypuff, and Peach have been left unchanged. Every other character in the roster has been buffed to varying degrees.
No. Those changes are in 20XX under the SD Remix toggle, but there are actually no changes for these characters in SD Remix. Fox and Falco are exactly the same as their Melee counterparts.
Additionally, Captain Falcon does not have a shine in SD Remix. This is also a change only present in 20XX under the SD Remix toggle. Instead, he has more subtle changes that you can see here.
This site hosts general patch notes for each buffed character, but does not provide in-depth information.
For in-depth patch notes, uglook, one of the official members of the SD Remix team, has uploaded them here.
