The non-feud continues, now as a homebrew game. Someone has developed a program for DS and PSP that allows the 2 to interact wirelessly with each other in a game of tic-tac-toe. If only Sony and Nintendo would allow this type of interactivity for big budget multi-platform games.
That’s unlikely, but at least we can hope for deeper homebrew apps that work this way. System (and fanboy) wars will never be the same.
