Yeah, I think at least some/most of them. It’s possible all Roger had to do was send in a few extra fighting grunts at least (Since I’m not completely sure if there really was enough for a full Smash Bros. voice pack. Maybe even a victory line or two)

But for example the line “SONIC SPEED!” that I said replaces “YOU’RE TOO SLOW!” was from Mario & Sonic at the Olympic Games 2012
