This is awesome! I really appreciate you sharing all that data out!
I've been working on compiling all my data into a huge excel file from my "expansion" of Yousei's file. You have far more data than I in a lot of places.
I'd be glad to supply you with what I have once I compile all my notes if you wish.
I hope you don't mind if I refer to some of your offset data when I work on some of my hacks! You would be credited of course for places I haven't figured out yet. I know how difficult it is to decode this crap.
An especially huge thanks for listing the natural magic learned data in your link. I've been leveling up one of the magic users level by level using Lord_J's FF4h utility to try and get a table of level = learned to try and find it in the ROM image... I've been wanting to tweak that for the longest time!
BTW: Do you have the locations for the treasure chests yet? I believe I have that figured out. Using the FF-II V1.0 rom image and the FF4 SFC rom image (I've found the offsetts in the FF4 Rom - they're different as I'm sure you know). I used a few game strategy guides to figure out the locations of the chests based on what they contained, and based on the blocks they were in within the ROM and where those groupings had to occur in places in the game. As long as the chests are relatively the same between the two games I think the location data I have for FFIV will convert to FF-II. There are the same number of chests in FF-II as FF-IV (though they're obviously in different places on the maps sometimes in FF-II)
I'm hoping to be able to restore the dummied items to the chests in FF-II... Though I've been hacking FF-IV (patched with the J2e patch) mostly...
Anyway...I'd be happy to contribute that (and anything else). In fact I'll try and share out my spreadsheet with that data tonight...
<edit>
Well here's my Item spreadsheet:
http://www.finalfantasyiv.net/emulation/documents/itemcompendium.xlsI'm sure you know most of what's there already. I only just noticed recently that the attack/effect/heal items were handled like magic. Anyway the data I'm working on with the treasure is in there.
Also I found the site here at lunch at work... I have been really pouring over your offset list since I've had time now. Some of what you've decoded is pretty amazing. I've never heard of anyone decoding the audio... that's awesome. Heh...I guess I should have paid more attention when I took assembly language...
Honestly thanks for putting your data out here. That's a lot of hard work to be generous with.
I'm not sure there's alot I could really share that it seems most here don't know already... I've been working with Yousei's data sheet and the ROM data in the Tower of Bab-il documents off Zophar for a number of years...besides doing graphics hacks...
We have EVEN MORE themes now, but some old ones are gone...
