Pet Project - FFR

I've been studying ASM for a month or so now. From the bit that I understand, and what I understand about the structure of FF6 (and all ROMS for that matter), adding anything to the game would be next to impossible. You would really have to rewrite the entire ROM. So, what you are wanting to do would be quite daunting and require expert knowledge of ASM. But, if you are that intent on this project, here's a good place to start: http://www.romhacking.net/start/

Good luck!

I'm no assembly expert, although I know of places in the rom that can be utilized for free space. You could add in your own assembly and tie it in with the code theoretically, as long as you don't go over the allotted space.
I made a patch which relocated some data so you could have more weapons and animations with them by moving that data to the empty non-used 2FFDC8.
