SD Remix Lite
This is meant to be played on unmodified consoles.
SD Remix Lite is a modified SSBM save file that contains an exploit that, when triggered, enables the SD Remix experience, like character balance changes, custom stages, and new features.
Because of space constraints on memory cards, the core change (such as character changes) and a limited set of secondary features are present. It is much easier to use, as it doesn’t require any hardware modifications (getting it is simply a matter of copying the save file of someone who has it to your memory card).
