What's New

10-01-2000

Updated the RAM data and spell effect data documents with a lot of new information. Updated the battle data record and elemental and status documents a bit. Added a document on the monster attack sequences.

09-04-2000

Added a patch: a new command for Rydia (once she has grown up).

09-03-2000

Reversed the bit order yet again, and updated the conventions document. All of the other documents now clearly state whether they use "normal" or "reverse" bit order, as some sections of the code use normal while other sections use reverse. All documents now include a date of last modification and the URL of this page. Some new documents were added. Some old documents had new info added. Re-read everything.

07-15-2000 evening/07-16-2000 early morning

Reversed the bit order in existing documents and added some more information on the conventions used by this site and the game program itself.

Currently, I have the following information typed up and online pertaining to the data portions of the ROM:

• An explanation of the text encoding
• An explanation of the character names
• An explanation of the character id byte
• The sprite/class id byte in character data
• What I know about character battle menu commands
• What I know about spells and enemy special attack data
• The monster data
• Some information about how elemental and status anomaly data is stored
• Information about the starting stat/equipment data
• Information about how the monster attack sequences are stored.

Currently, I have the following information typed up and online pertaining to the data structures in the RAM:

• Some significant locations in RAM
• The structure of a character/monster data record

Currently, I have the following information typed up and online pertaining to the code portions of the ROM:

• Some information about spells/special attack code

Before reading any of the other documents, please read this first.

Or perhaps you are more interested in practical applications of this knowledge. I currently have the following ROM patches in IPS format available for download:

• This patch will give Rydia a new command to replace her lost white magic when she matures: a random called monster that costs her no MP.

Most of this information was the result of a lot of my own hard work hacking the game, although some of it came from the document written by Yousei that is included with his/her/its FF4 Editor.
