Does anyone know of a website or book where someone has analyzed (in detail) the battle systems from classic turn-based RPGs like FF and Dragon Quest? 
I'm looking for anything -- documentation by rom hackers, interviews with original developers, articles on game development sites, etc.. Anything that can give me the actual math being used. 
 
I'm working on a few game programming projects in my spare time and I've been giving myself assignments that run through different stages of game development.
I've got a fairly robust interactive fiction engine working and I'd like to move on to prototyping various parts of some early 8 and 16 bit games. I'd be happy to share some of the results here if anyone's interested.

bumping once, just in case someone knows and missed it.

Yeah, I'm planning to direct this at more specific people at some point, but I wanted to start by casting a wide net and seeing if it hadn't already been published somewhere. 
 
I think this could make a pretty fascinating study even without doing the prototypes.  I'll check with some rom hackers directly or maybe try to analyze a couple of them myself.

These aren't exactly what I was talking about, but they are excellent pointers to the kind of data I want. I'm just going to leave it at this, but if anyone finds anything else like this out there on the web and sees this thread, I'd appreciate them posting it here.
