Phantasy Star: Deluxe Edition, the PS1 remake for mobile phones, has (finally) been leaked online. Credit goes to orakio_rob for finding the game online, but I had to remove his post about it because he linked to it and unauthorized distribution of commercial games isn't allowed here. I'm sure you'll all be able to find it if you're really interested, anyway.
The leaked version is a Chinese version of the game, so it looks a little different than the screenshots shown on the Deluxe Edition page here. They come from the Japanese version. This does appear to be a real, official release and not a pirate version, though. You can buy the Chinese version here: Mobile Market. They also have some screenshots if you want to compare them to the Japanese version.
I have already extracted some images from the game, so they'll be going into Image of the Day rotation soon. One should appear today, in fact. It's also the source of my current avatar, which is Dark Falz from the game.
I've also extracted a ton of text from the game. I think it's the complete script actually, but it's all in Chinese so I'm not entirely sure. Google Translate is little help, but does lead me to think this text includes all the dialogue.
