This had nothing to do with a official NFSU 2 support. A patch has been placed on gamecopyworld including the US cars. Now there was no 'readme' file within, so here we can share our solutions. Isn't that the meaning of a forum? No offensice at all, but I just have the same problem. The patch isn't working
Edit: I found a way to solve the problem, but I need the help of someone who has the civic and Rsx in this game (north america?)
