alright its not really "new" but ive managed to trigger it 4 times in a row, so you guys might want to give it a try see if it works.

use the fast frame button to skip through the intro and in the main menu screen just hold it there for a 15 seconds or so.
then take, ottawa VS the ducks. (ottawa has to be the away team)
Automatic goalie, defence control on
play as ottawa, get a 2-0 lead. (but not in like 20 second, i played out most of the first period)
then let the ducks score.
I dont know which part of these steps is crucial to the glitch occuring, but i did this exactly 4 times in a row.
and every time anaheim scored after being down by 2. screen would scramble, one out of the 4 times it split in 2 halfs.
also one of the times i did it, the screen would scramble, i used to skip frame button to speed things up, it fixed it, but then all the players on the ice didnt have there number and position.
so i dunno! it happened 4 times in a row so i figure its reproducable by anyone, give it a shot.
