Lin and I have now released a demo for Oracle of Nature, read the topic for some info on it as well as to download it

It is a map script that causes the sand tile to appear there. In ZOLE if you go to an unused room in your hack and open up the map script chooser and swap with maps 98 it will remove the map script from 98 which will stop that tile of sand from appearing.

Welcome to the forums Kishin, I hope you enjoy your ZOLE hacking experience If you end up making a hack definitely post screen shots, screen shots feed everyone on the forums, and if you have any questions feel free to ask for help here on the forums or on the ZOLE IRC (check the IRC topic in the announcements forum for details).

Now I don't like to brag, (ok I do) but that is a lot of interactions. And that lot of interactions has royally destroyed the ROM I use. Oh well the ROM isn't important all that was there was some shitty lost woods some loser made and stuff. What is important is that Sir Loser McFace has returned, of course this only happened one time so I wouldn't think too much of it, but just have to let you know Lin.

Im pretty sure you mean decompile.

ZOSE will only decompile dungeon specific events (20xx) and custom scripts 72xx to a readable, editable state. This is because 20xx and 72xx point directly to the scripts. You wont be able to view scripts that are on the overworld using ZOSE

Here is an extensive list of memory addresses for various things in the Legend of Zelda Oracle of Ages. This is for Oracle of Ages ONLY. Although OoA and OoS (Oracle of Seasons) are very similar the memory addresses are not in the exact same locations, nor are values the same. You can use these memory addresses in the VBA (Visual Boy Advance) Memory Viewer to edit various aspects of the game, or if you have knowledge on gameshark codes you could easily make them into gameshark codes for stuff such as permanent pegasus seed use.

Oracle of Ages Memory Address document written by Fatories. Special thanks to Lin for giving some memory addresses and helping with a few things.

Other than a few memory addresses given by Lin, all were found using the VBA memory viewer by myself.

[Stream is long over, thanks to the people who came and watched lin play some OoT]

EDIT: Stream is long over, thanks to the people who came and watched lin play some OoT

Lin is hosting a stream right now of Ocarina of Time starting at the forest temple, and we will be answering questions and discussing are hack. If you have questions or would just like to hang out and watch him play then come check out the stream at:

Mine was probably the whole level 6 region (whatever it might be called). It wasn't that the ideas were bad or anything, but when playing I hated how you constantly had to play mini games, get an item, move on to the past and do more mini games and crap. I also hated how its all pretty much the same mountain area as level 5, it felt to me as a kid when playing that I was on those mountains for an eternity, when really I wanted to get back to exploring the world and filling my map.

I've been looking for the way into the desert and that walrus is blocking the normal route.

He removed the walrus so you probably have an outdated version.

So I'm up to the Beach Cave and there's been a few stray bugs here and there.

Like chests in areas with no obvious puzzle. I'm in a room in Beach Cave and I lack a small key. There's a tone in the room with two vases in a maze-like area. What am I supposed to do?

That's not Luigi's fault, ZOLE cannot edit the minimaps/compasses of dungeons. As of now, dungeon compasses are completely useless and will only throw people off if you use them, so dont listen to it.

Luigi has posted all the maps of his hack so if you are stuck just look at them because they tell you what's in each chest.

[You will require ZOIC and ZOSE for this tutorial.]

So you've been at ZOLE for a while, working with those dem fine chests, and you've finally come to the point in your hack where you need an item to appear in a side scrolling screen (like the power bracelet or rocs feather). Now you're a smart person and you've tried, you've looked for all possible ways to do this before coming to the tutorial but you've finally given up on doing it. Well don't worry I'll teach you how to do this step by step.

You will require ZOIC and ZOSE for this tutorial.

1. You will need to make a custom script in your room using ZOSE. If you are unfamiliar how then you better go learn how, I have a tutorial on it which can be found here: http://zeldahacking.ulmb.com/index.php?topic=274.new#new

In this script you will have to write to simple lines.

Code:

writelocation xxxxx
setinteraction72 xx
checkitemflag
spawnitem X Y

The code may need to be altered around a bit with such things as "set coords", I trust if you are following this tutorial you could at least be able to figure that out.

The X should be your weapons first ID and the Y should be the second one (For power bracelet 16 00, etc).
Check out the weapon list here for your weapon ID: http://zeldahacking.ulmb.com/index.php?topic=10.0

2. Open your ROM in ZOIC. In ZOIC enter the ID of your item (1600 for the bracelet, etc) and values should be loaded. In the item property value change whatever you see there to 0A. Then click the change item button.

There you go folks, three simple steps to making an item appear in your side scrolling room.

[Chest IDs:]

This is just going to be a short list of interactions/items you would mostly use inside of a dungeon. If you feel I should add something, then go ahead and leave a message, I'll most likely add it in.

Chest IDs:

Small Key - 3003
Boss Key - 3103
Dungeon Map - 3302
Compass - 3202

Type 2 Interactions:

Small key that falls down when enemies are killed - 1201
Chest that appears when enemies are killed - 1202
Chest that appears when switch is stepped on - 2117

Switches (Type 8 Interaction):

90x - Switch that stays pressed
98x - Switch that doesnt stay pressed when stepped on.

* - The "x" value depends on how many switchs of that type are in the room. 900 for the first switch, 901 for the second, 902 for third, etc. Same with 98x.

I've added my version of level 2. In my video I have an updated version of our ROM, so there is none of the bugs found in Lin's video, enjoy.

So I had this idea in my hack where at one point I needed a warp, something like the one on map F1 of map group 5 (Twinrova/Ganon battle warp, when you go to rescue Zelda). Now I could have spent my time building my own script, but rather than doing that I decided I'd find the address for the interaction and edit it myself. After about half an hour (give me a break, I've never done this before ) I finally was able to find the address for a few things, and here they are:

0x4BD4 - Keep first number as an 8. Second number is destination group.
0x4BD5 - Map you are being teleported to.
0x4BD6 - After the inital warp, this is how you will enter the map you get teleported onto (0x05 is the traditional fall down from above).
0x4BD7 - The position you will be put on, YX form.

Thats pretty much all you need for editing, at least thats all I needed so I didn't test anything else. Basically, just change the bytes to the appropriate values. Don't forget to add the type 2 interaction DA00 into your map, it will activate when Link steps on it.

I must say, these maps please my eye. Well done, I look forward to more.
