I don't know if anyone else has had this problem or not with N2.
Everytime I played the game in Dos mode it would let me play on one track,
but if I tried to race on another track, every time I clicked on race it
would lock up. I found a way to get around it and keep it from locking
up. Don't put the cd rom in. When it first starts up you won't get the
intro instead it will say abort, fail, retry, etc.... Just hit your "a"
key and the game will start without any problems. You wont get the intro
with the cars going around the track, but what do you want? It's either
that or the game. Me, I'll take the game.
