I'm gonna try to tell this as best as I can
So apparently CSS codes don't work on dolphin but it will work if you put the codes on a Virtual SD Card. But when I do this it always resets the game (the screen starts up with the "Create a new save file" screen as if i don't have one. And when I try to create one it says I don't have enough storage) meaning everything has to be unlocked. How can I stop this from happening ?
With Dolphin, gecko codes are best launched through the Gecko OS Homebrew App or Project M's launcher. Also, if you're using the BrawlEx CSS Expansion mod, a custom CSS code should not be used. It handles the CSS through cssroster.dat instead.
