I played the game back in the CD days (6 discs worth, as I recall), and I played through it a couple of times to get the best ending. I know exactly where my path started to diverge - right when Tex asks Chelsea to go to the club. In my very first playthrough, I managed to somehow have her turn Tex down, so he'd have to sneak in another way. However, I forgot to save after that, got killed, and have never managed to repeat it again. With GoG having a special on Murphy games, I thought I might give it another try, but can anyone give me advice on how to avoid making her mad at the club this time?

The first time the paths start to diverge is the very first conversation with chelsee in day 1.
The only tip I give on that conversation if you do it right you have to talk to her twice to get her to go out with you he will say that you might have a chance if you talk to her again.

the only way to get the best ending is for tex to go the the flamingo alone & yes its related the first conversation with chelsee
