After playing through this game, I figured I'd tackle the task of ripping the game scripts. Apparently some tools already exist but I've been unable to track them down as they were old as heck (~2004-2005).
What I have so far is far from being perfect, with a number of script commands as of yet undetermined. Then again, I started this about two days ago, so... ya know. :)
Note that pretty much everything in the game seems to be handled by these files, and not just events. The events are mostly fine with only a few minor commands missing for the most part. More code-related stuff doesn't quite come out all that well yet. Have a look at the op_* files for the opening scenes, mb_* files for battle events, and most of the ones starting by a character's name (ex, aru_m1_010).
Also worth nothing,
Var_007F = FFFF;
Var_0085 = 0000;
This series of instructions is used to make the name of whoever is talking blank. Not too sure why (especially considering there's a command to change the name already) but whatever.
I'll probably have a better version at some future date. Enjoy!
