I was browsing the forum and I noticed that nobody has mentioned Golden Sun! For those unfamiliar with the title, It's an RPG develouped be Camelot revolving around the power of Alchemy. It's plot spans over two cartridges, though though it wouldn't be considered a sequel. Golden Sun the Lost Age is a continuation of the same story. It's a very popular "series" and fans have been craving more of it.
Admittedly, Golden Sun would be a very daunting task. It's a darn long game, and the stats/class changing system involving the Dijinn would be a very difficult thing to strategies. At speeddemosarchive it was a popular forum topic for quite some time, but the project was abandoned.
If you want to try the run, I suggest you read this topic on the speeddemos forum. Lots of great info. It looks like the game was just about ready for posting, but it's never been done.

You might also look at this guy's route plan he's sharing in this thread.

I really wish and hope someone would run this game as it's one of my favourite games ever, and it has quite a fanbase. I even have the 4koma manga of it!
