Hello. I'm sorry to revive such an old topic, but I have the same problem. I can't check court record.... I'm using Ubuntu Lucid 10.04 and the latest Desmume from the repository. All of the other Phoenix Wright games work perfect, except this one. And the thing that really gives me trouble is the following - a clue, which I supposedly get from the crime scene doesn't appear, when I hit "Present" (it's the same as court record, but it's purpose is to present the evidence you've found during your investigation. In my case - it's a broken car mirror from the 2nd trail. Unfortunately I have no idea how to post this problem in the bug tracker....
About the windows version solution - yeah, I could do that with wine, but it'll be hellishly slow. I also could use my windows PC, but that doesn't work for me, since I play the game on my laptop, when I'm out of home.
Please, help me with this problem!
