Hello everyone, I wanted to share with you a link that I found on YouTube in the comment section that is the Alien Resurrection for the Ps1 (with emulator) and already configured to play it with mouse and keyboard. I found a good time ago, 2 month maybe, and I didn't have any problems with it. It plays smooth with the mouse, there aren't any of the door bugs that happen in the most of the emulator's with this game. I already won it on Easy difficulty (I know but everyone who played this game knows of difficult it is) and now I'm replaying it on Hard difficulty (now I'm on the Christie level). For my personal opinion this is one of the best Alien games ever, maybe in tie with Isolation.
