I'll look, but only if it hasn't been found yet. LTTP is not one of the roms I am intimatly familiar with(unlike LA and OOS in which I am king there).
I've been working off of a disassembly of the game, but obviously ROM corrupting is a more valuable tool than I originally thought if you were able to locate the data so quickly. I know I'm starting to get just a *bit* off topic, but if you do become interested in hacking on Zelda 3 yourself, just send me a message or email and I'll get you some of the more detailed documents I've been using, (with the author's permission, of course.)

Posts: 979/1773		 Glad to hear it, GM I've been looking foward to this hack, I've played zelda 3 to the point where I can beat it eyes-closed, I can't wait for the new maps and everything your roof idea is awesome, btw.

Posts: 144/179		 Well I wasn't expecting to make a major contribution to the project. I was just curious how quickly it would take me to find the data via pure rom corruption(half an hour).

After about a half hour of rom corruption, I found the boss drop data, but there are some complications. First of all, the heart container is not a sprite on the sprite index. Instead it is composed of a graphic, and a what I call a "live chest". This means the data for the heart is actually treasure chest data, not a sprite. This is good in a way because if hacked, it could be possible to have certain monsters drop more than just heart containers. The heart container that the boss drops is called "muteheart" and is inded 62, or 3E in hex.

However, there are 2 other problems not including finding the heart graphic. The first is that you can only use treasure chest values, and heart pieces do not have an entry. It could be corrected if the treasure chest assembler is found. Second, the heart container contains code that further introduces the pendant/crystal. Any other item causes the game to hang. For this to be corrected, the code that makes the game continue would have to be edited to the item that's desired, or the item data would need to be copied to entry 3E. Either way it will take some more work to make it work.

This is my initial finding. If I find anything else, I'll post it.
You may want to contact GM before spending your time working on some of those ASM requests. I've already sent him a fix for the "Boss Hearts" request, but I'll admit it isn't entirely perfect. I'll send you my most recent patch in a PM, if you want to look at it. I didn't make the heart piece behave like a "live chest," as you've named it; the "you've just got a heart piece" message pops up when you get it, and if you're in a room that's not just a quadrant (such as the giant moldorm boss fight), you'll see the crystal/pendant appear, but not fall until you hit the button. The only real problem is that if you collect your "fourth" heart piece, the crystal/pendant GFX will become a heart when Link holds the full heart over his head. I've been meaning to get back into the code to fix this, but I haven't gotten around to it.

Posts: 335/387		 It's great that you have a place for updates. Out of any hack I've waited for, this has to be the best.

It will be much easier to follow now that you got a site.

Posts: 142/179		 I wonder how many miniutes it would take for me to find all that ASM data you are looking for? To be honest, all of them should be very easy to find via rom corruption and knowlege of the game's ram. I haven't started on SNES assembly yet, but if I ever finish my Blaster Master hack, maybe I can go take a look.

Posts: 110/150		 Those moblins look sweet. Always nice to hear on your progress GameMkr. It's odd how you seem (IMO) to be the only hacker who's successfully created a website to go with their hack without it being a gimicky thing. Pics and news updates are always a pleasure to read.

Posts: 161/196		 Nice, I like how you also have the Outlands page there too. I'll be checking for updates regularly again.

Posts: 32/52		 Yay!

Man, every time I read an update, I want to play it even more!

But, anticipation is good. But I still think you're evil for taunting us wth this awesome looking game.

I love the Moblins and Goryias, but the Armos Statues don't seem to fir in. Maybe it's just me, though.

Sorry for the long delay -- I've been without a website for a long
time now. I'm finally moved in to my new address, located here:

Thanks for the patience and support!
