Read from nintendolife:
Ryoichi Hasegawa: There was one funny story...There was artwork of Mario and Sonic, and you know, other characters standing on the field. And those artworks were used for the package, the instruction manual cover, and the cartridge label, and things like that...There was one small error and Sonic's foot was in front of Mario's foot, and Nintendo demanded us to change the priority".
Arcade Attack: So, what? Mario had to be slightly ahead? Oh, for goodness sake.
Hasegawa: (nods) Yes...I still remember that.
Aracde Attack: And you did change it, I take it?
Hasegawa: Of course, of course, we were like 'oh my god' we have to change it, or there will be no deal.
