nfl gameday 99 freeze-ups

I was wondering if anyone knows a fix on playstation 1 ...nfl gameday 99 how to fix game from freezing up at crucial points in preseason matches.same thing ,both teams seem to gather together with their own teamates and look away at something that puts them in a trans and they do this one at a time. Cant do anything.

YES I KNOW ITS TIME TO GET A NEW SYSTEM.But my friends and I like to create own players and release,then create more players til we have most of the team all created players. I have gameday 2000.but cant seem to load all created players together.

any help will be appreciated! thank you.
