WipEout HD

This trophy isn't that hard if you use the glitch. The glitch is done by you setting up two controllers and racing on split-screen. This way the A.I slow right down as WipEout has a system where the slower you are going, the slower the A.I go, and as Player 1 isn't moving, the AI are slowed down. It doesn't make it that easy though, the reverse tracks are still brutal if you haven't played them before. Firstly you will want to go to "Racebox" and set the game mode to "Single Race". Put the speed class on "Phantom" and then the A.I on "Elite". Only do the next part if you want to glitch it. Now plug in a second controller and put the players up to 2, choose how you want the screen to (horizontal or vertical). Choose a race and the start, now just race with Player 2, don't do anything with Player 1. You will notice the A.I are a lot slower. Be careful though not to smack into player 1 as that will slow you down a lot. If you do this on all 16 tracks then you only need to do 4 more split-screen games for the Gemini trophy.

I highly recommend using the glitch if your having a tough time, especially on the reverse tracks. I struggled on a few of the reverse tracks even using the glitch, the small screen doesn't help either. You can check your progress on Arcade Perfect by going to "Options" > "Extras" > "Statistics", on the bottom of the first page there's 16 track logos in squares, the ones in grey mean you haven't beaten them on Phantom and Elite, the ones in red mean you have. Once they are all red, the trophy will unlock.
