Hello there. Sorry for my insufficient wording.
When I said “wireless multiplayer”, I actually meant local multiplayer (VS and battle via DS download game or multi-cartridge), not online. But both is by definition wire-less.
The loss/win records do not alter the gameplay itself and also not the records of the other player (if playing using the cartridge.)
That loss counter just feels like a stalker to me. What I was asking for does not affect the other players at all.
I just wanted to apologize for my poor choice of words.
