NHL 98 from EA Sports is a great game with superb graphics and gameplay. Body checks will kill you unless you know the codes. Try these codes although I'm not sure what they'll do except for the obvious ones of course.

type these in during a game: MANTIS, HOMEGOAL, AWAYGOAL, NHLKIDS, PENALTY, INJURY, ZAMBO , VICTORY , FLASH, SPOTS, CHECK and GRAB
