Really neat - works fine in Fceux.

...BUT...the patched rom refuses to load in Nestopia - is this something you might want to look into?

Also, are you supposed to have to press select twice to do the actual switch?
The first time you press select - you get a preview of the character you will switch to - the next press triggers the actual switch.

Wouldn't it be faster/easier to only have to press select once?

Anyway - good work!

Took a stab at altering the title-screens and started with the first of the three that is in this game.

The old one - that displayed the logo of the maker:

Is now replaced with an homage to the Ocarina of Time:

I have a pretty good idea what to do with the Main-title screen and the Credit screen - but nothing is final yet.

Oh - before I forget, thanks everybody who have commented and provided constructive criticism to my posts.

EDIT: I noticed that the hilt of the sword looked a bit off... rest assure - I have fixed that in the game.

I just added a little poll to the first post of what zelda character you would like to make a special appearance in this hack.

As a teaser of what might be - I have already prepared sprites for Midna and Skull-kid:

Took the time to investigate how to predefine the gray-scale palette when running the game in a emulator using the color-bios (for example gameYob on nintendo DS).

After some googleing and reading I was able to put together a bat-file that will set the gray-scale palette for any rom dropped on it.

Here is what you need - if you want to try it yourself:

Download the package that contains the executable:

Create a bat-file (in notepad) with the below command:

Code: [Select]
REM -t: set the internal title of the rom
REM -l: set the internal licensee code
REM -v: validate the header and fix checksums
rgbfix.exe -t X -l 0x01 -v "%~1"

The BIOS will think that you are running the game "X" and will select the gray-scale palette for you by default.

Just finished the in-game Zelda sprite - hopefully I can insert it during the week-end:

Quite a improvement upon the hideous original - don't you think?

I think Spirasen are referring to the gameboy port of Battle of Olympus - that is kind of rushed/buggy - NOT Zelda 2 for the NES.

The reason I choose the gameboy... well... Zelda 2 already exists on the NES - the gameboy should have one too. Also, I wanted to hack a gameboy game for a change.

Well - since I can't find the short Amazon, I am done with the enemy replacement:

Slime (Worm) - Bit/Bot: This one felt like a spot-on replacement
Little Bear - Geru: I made the lizard-man really tiny in order to make the replacement
Satyr - Wosu: This one was really easy, basically copy-pasted the bouncing rat-man and added some shadow
Scorpion - Aruroda: Adapted the scorpion to have a opening/closing eye - that's about it
Bat - Ache: Added claws and some shadows
Snake - : Hard to adapt to anything other, has to leave skin/scale as loot - so I just redesigned it
Jumper - Tektite: This replacement makes sense since the forest is covered in cob-webs
Eagle - Moby: Original was way more detailed - so I just added Moby's face and beak
Monkey - Megmat: Same movement pattern - easy replacement
Flying Fish - : Again, hard to replace - so I made tiny updates (might considering using a flying head like Ra/Mau)
Shadow - Stalfos: No shield for Stalfos, instead he gets to walk upside down
Tall Amazon - Dread Hawk: Since I was going to use Iron Knuckle to replace the short Amazon, It made sense to use a similar but different adaptation for the tall one. Instead of jumping around - the Hawk got a lot taller.
Ghost - Moa/Girubokku: The combination of the two different flying ghosts works fine
Slug/Pill Bug - Lowder: It is a faster Lowder, but now he also sleeps
Butterfly - Boon: Made sense - an insect for an insect
Fire Flower - Deku Baba: Borrowed from Ocarina of Time - spits nuts
Gargoyle - King Bubble: The gargoyle came in two flavours - so I made up the one without the horns
Giant Snake - Carock: I know that Carock IS a BOSS, but the limited movement pattern of the giant snake matched Carock perfectly.

As always - nothing is set in stone and everything might be subject to change...  ;)

I'll keep what version of Zelda that made it into the game a secret...

I'm almost finished with replacing all the enemy sprites (Except the BOSS enemy sprites - that are going to take some time to get right).

Here is my current question though: Whatever happened to the short Amazon enemy in the gameboy port?

IronKnuckle (the Zelda 2 version of DarkNut) had been a perfect replacement for her.

I can see the tiles for the enemy using Tile Molester:

But I can't find her anywhere in the game. Can anybody confirm that the short Amazon was cut from the gameboy port - so I can stop searching for her?

So I fine-tuned Zelda some more and made two versions with white as skin-tone.

I will probably go with the one on the very left, I think white as skin-tone make her look too pale:

I... don't think Zelda should be so scantily clad. It just doesn't seem fitting of the Princess of Hyrule to go around in a low-cut blouse. Aside from that, you did quite a good job on the rendition.

Well...she is playing the part of 'damsell-in-distress' in this game...

But you got a point - so I tried to make her more Zelda, and less Wonder-Woman:

Is she decent enough or should I put her in a turtle-neck?  ;)

Tell me what you think.

Nice - if someone could add that onto the Battle of Olympus title-screen - I would be over-the-freakin'-moon...

Anyway, when I made some progress in the game I realized I have assumed wrong, regarding placement of the final level-entrance.
Soo - I updated the overworld map accordingly:

I also got around to finally make Zelda herself appear in the game:

That's about all for now.

You could take a look at the following document:

SC: Cool you found this hack interesting and I have made a note that you are probably not going to play it.  :P


So I found the pointer that enables/disables eagles in Crete. In fact, I can now disable all eagles if I wanted to (I hate those pesky eagles) but I will most likely only disable them on Crete.

This hack was never intended as a port of Zelda 2 - it was meant to bring the Zelda 2 type of game to the game-boy (within the Zelda universe).

Also, there is only so much you can copy-paste when you are not dealing with a direct port.

I had similar problems with my Kid Icarus hack (Angel Land - Retold: but then I could solve it by simply shuffle around enemy sprites or reduce the bosses size in order to fit the rearranged tiles). This is however not possible for this hack - I have no dolphin or flying horse to copy from Zelda 2.

Don't worry though, since 'Battle of Olympus' share many common types of enemies - you will recognize quite a few from Zelda 2. For now - they are just touched up versions of the originals ripped from Zelda 2, but I'm considering tweaking them into a more unique look - still keeping enough features to be able to distinguish what enemy from Zelda 2 they are supposed to be.


The hunt for the pre-mentioned bug have resulted in the following knowledge:

1. The rom-offset for the tile-compositions of the eagle are located at 1 5C0F & 1 5C36
2. The rom-offset for the pointers to the above mentioned compositions are located between 1 448B & 1 449D

Question is - how do I locate the pointer(s) that point to offset 1 448B to denote: insert an eagle here at this level?

Damn it Chpexo...but when you are right - you are right.

Fact of the matter is, that I kept the Pegasus wings as they were - thinking I could get away with it....

So, I did a redesign of the wings and made a little anim of the new result:

As for the music - if anybody got the skills, don't hesitate to take it upon yourself to start experimenting with inserting Zelda tunes into Battle of Olympus. If you succeed and share that knowledge/patch with me - I'll split the fame & glory, come release day, with you  ;)

Whoever was responsible for this port was obviously in a hurry - I found another annoying bug in the original.

Here is the temple of Crete with the background switched off:

Can you figure out what is supposed to fly in the top-right corner - that's right an eagle!

It's just that the tiles it requires are now occupied with other graphics!!

So now I have to figure out what pointer I need to remove - not to have eagles appearing inside the temple in Crete.

Oh - Joy!

He looks perfectly fine when jumping - as you can see below:

Couldn't replace the stupid dolphin without doing something about Pegasus - right?

So...I replaced him with the Crimson Loftwing from the Skyward Sword:

I might tweak this one a little - but I think it turned out pretty decent, considering the limitations presented - both in tiles and colors (Black/White/Gray)

It may take a while before I post anything new again, but trust me - this hack is going to get finished... someday...

Lazy-ass programmers forgot to add all graphics when they made the gameboy port.

So now, instead of a white place-holder, you actually get to burn down some wines:

The title is not set in stone - but I like the wordplay with 'Missing Link', maybe I'll keep it..

When it comes to modifying the game mechanics, people usually mean stuff that require ASM - like adding the downward thrust technique from Zelda2. Even if I had that kind of skill, which I don't, I doubt there is enough free space in the ROM to add anything that fancy.

What I will try to do, towards the end of this project, is to eliminate the life-cost when using the divine sword (or the master sword  ;)) to shoot lightning bolts - this really annoys me as it functions now.

I have a update to share - I have replaced the dolphin with the King of Red Lions from Wind Waker.

Since Link now can traverse the seas properly - the only thing left to say is:

Facka Yuu - Dolphin!

You mean this particular train-wreck of a game:

I played it for about 5 min or so.... then I got depressed...

Here is a screen-shot of the map-editor I had to make, in order to fashion the replacement map:

Since I have made some progress with this hack - I thought it would be in order to share a little info.

First of all, this is a hack of the gameboy version of the game 'Battle of Olympus'. The overall ambition is to alter the script and gfx to fit a Zelda storyline. This would mean that the gameboy would finally have a Zelda 2 game!

I have altered the main-character and the HUD:

The character style of Link is an adapted version of the sprite originally made by Thanatos-Zero (,12330.60.html).
I have chosen hearts for the life-gauge (even though Zelda 2 used a meter) - since that felt more Zelda to me.

I have altered all the items attainable in the game and the item select menu:

I went with a rod, rather than a staff and fragments of tri-force, rather than fragments of love.

I have altered the overworld map and the locations:

The overall style is a combination of the original and the style of map found in the gameboy Zelda's (awakening and oracles).
The locations all have names borrowed from other Zelda titles and I have tried to match the name and the environment to some degree.

Sooner or later, I probably want to take a stab at altering the sound and music. Unfortunately - this is beyond my current skill-set so this will not be a priority and quite possibly never be a reality.

With that said - If you know how to alter music in gameboy games and like the idea of Zelda 2 for gameboy - PLEASE, don't hesitate with giving me a hand with this.

Oh - I also have programmed a .NET application for script alterations, so I can edit and re-edit the script while playing the game.
This handy tool will also be made available to those willing to help me translate the script-alterations to other languages. The original game supports English, German, French, Italian and Spanish - But any language (that does not require any unique characters) could be inserted into the game.

Big thanks to Bailli - who helped me with decoding/understanding how the script and overworld map are stored in the rom.

That's all for now - I'll update this thread as soon as I make any more interesting progress.

The new map is inserted - I went with a mashup of the map in Link's awakening and the original one:

The above image is taken from the debugger-tool in VisualBoy Advanced - so the sprite-layer (the towns) are not visible.
Had some serious issues with the pointers - but managed to get it sorted.

Here is the 'translation' of locations I have been tinkering with:

Arcadia - Ordon (Houses & Trees)
Attica - Ruto (Houses, Beach & Cliffs)
Argolis - Eldin (Caves & Beach)
Peloponnesus - Faron (Woods)
Laconia - Mido (Pillars & Beach)
Phthia - Darunia (Mountain & Waterfall)
Crete - Ikana (Beach & Dungeon)
Phrygia - Tantari (Beach & Dungeon)
Tartarus - Dragmire

Have some pretty nice replacements for the location-icons, they will be inserted next.

... So far, the only other game I can remember that did this was Kid Icarus.

Hey, I made that hack. I have actually updated it with a custom title-screen (and some other gfx updates) but newer uploaded it. If you want me to - I could upload it?

Sorry for hi-jackin your thread there Contra  >:D
