Gaming R4 real time...?

[Waddle Dee]

I was looking at my R4 cheat function, and... it has a thing labeled "real time on/off enable(B)". What does this do? I hear something about being able to save anywhere, but how do I work that?

It allows you to activate or deactivate your cheats while in-game. Press L+R+Up to activate and L+R+Down to deactivate.
