Cool, I'll try this in a second!
Kind of a weird question, but do I hold L when I'm in the Character Select Screen (kinda like the built in ZZS code Nintendo made to start with her at the beginning of a match)
or
Do you hold it down when you pick the stage?
Also curious if you can play using a character against a PSA of that same character (like Sonic vs Shadow PSA) or if each match loads from only one of the two Fighter folders making that type of scenario impossible?
First question. Hold L when you pick the character and hold it until your music starts messing up a little bit and for stages just hold L when you pick the stage. Just remember it will also load your alternate strm folder.
Second question. I'm not sure if I tried or not. I'm pretty sure I did try that and it did work though.
