1. Will I lose any functionality?
2. Will my ds have any problems communicating with people without flashme?
3. Is there a way to restore the original after I use flashme?
4. I have mario kart, will there be any problems using flashme since I've already saved my settings using mario kart. I don't plan on playing online anymore so I don't mind not being able to if that is the case with flashme.
TIA, I want to be sure of the consequences of what I'm about to do before I do it.
