I wish there was a decent DS emulator, I really want to play Castlevania: Portrait of Ruin.
Right now I'm playing a game called Starless Umbra, it was made with RPG Maker 2K3 by Dragonheartman.
Here's the link: <a class="postlink" href="http://www.starlessumbra.com/">http://www.starlessumbra.com/</a>
There are some really amazing stuff out there that people have made with RPG Maker 2000 and 2K3, some of them are better than commercial games. One example is a game called The Way, the only other game that has a better storyline is Planescape: Torment, and The Way was created by one person.
Anyway, Starless Umbra is pretty cool so far, it's got a lot of unique functions and what seems like a great story.
