Ok, a few steps closer to perfection. The improved code now cycles to the next arrow type you have available. So if you have regular and ice only you can switch between those. Any missing arrow types will be skiped, except for the regular arrows, since... Well... Those are obvious the most basic and weakest.

Perhaps not as useful for Majora's Mask since you will obtain each arrow type in sequence anyway.

Buuuuuut, this is going to be useful for Ocarina of Time since the ice arrow for example is not mandatory. Now... I just need to port it for Ocarina of Time and Master Quest.

Short said, use the D-Pad Right when you Bow is pulled out to quickly switch between arrow types. You do need to pull out the bow again, but at least you can skip going to the Pause Select screen. The intention is that you can only switch to the next arrow type if it is in your item possession. So you can not switch from Fire to Light if you are missing Ice, since Fire will toggle to Ice.

I should make one for Ocarina of Time as well...

You will be required to update the following code:

Code:

$Majora's Mask -> Hold D-Pad Right to Levitate (PZLE01) (AR Code)
CC140978 4E5A5345
D0E68E26 0000FF08

4A1410C2 00000002

This prevents you from using the same D-Pad Right button to levitate when in First Person Mode.




I am not really sure how to explain AR / Gecko coding to you. I tried looking into that 32:9 widescreen for ya, but I kinda get tired of it due how complicated it quickly became. Originally I intended to just adjust the 16:9 Aspect Ratio Fix + Extended Draw Distance + Hires Link Model code, but that didn't really work out either. I did include some parts there such as the Hires Link Model, but darkludx was responsible for the 16:9 Aspect Ratio Fix.

The easiest to modify would be:
$AR Code Ocarina of Time No Clipping 16:9 Widescreen (darkludx)
04136840 BFAB0000

Except, I don't think it works anymore due the changes in the code handler.

The widescreen codes from https://forums.dolphin-emu.org/Thread-ar-codes-for-ocarina-of-time-master-quest-majora-s-mask?pid=407343#pid407343 seems to still work. https://forums.dolphin-emu.org/Thread-ar-codes-for-ocarina-of-time-master-quest-majora-s-mask?pid=408346#pid408346 should be even easier to look at. Most of these codes were made for the Master Quest disc, but porting the codes to the different OoT version has often proved to be the least of my issues.

Ocarina of Time is quite specific when trying to adjust these values for widescreen, as it can simply break emulation. Which means a lot of rebooting and retrying. You can't really usefully change the values in real-time since the game won't apply them unless when being booted with those changes.

As said, this will probably be the easiest to adjust.

$16:9 Widescreen AR Code for Master Quest (darkludx)
04AEAF2C 10000023
04B5849C 3C073FE3

$21:9 Widescreen AR Code for Master Quest (darkludx)
04AEAF2C 10000023
04B5849C 3C074015

Of course, everything has to be more complex than necessary. The default values (4:3) are:
80EAEF2C 45000024
80B5849C 44079000

Which doesn't make it really that much easier to determine the differences.

You should at least familiarize yourself with https://github.com/dolphin-emu/dolphin/wiki/GameCube-Action-Replay-Code-Types to learn about AR Code types.

The best way to start out would be to just create a simple and useful AR Code. Try to expand upon that a bit more in time, and you eventually learn more about how conditional code types work for example. At least, that's how I did it at first.

Thanks for the tips and help, i found those codes when searching around too and tried to change the last line of code, but it didnt work. I read one post where someone said they get their hex codes for aspect ratio by dividing say 1920/1080 = 1.7777777 (he said 8 #'s was most accurate) then plugging it into: https://www.h-schmidt.net/FloatConverter/IEEE754.html gives the hex code, it actually worked for animal crossing adjusting the 16:9 code for the game. other games didnt prove as easy and i couuldnt make it work, or it was a gecko code.
Applying this method to master quest makes it stall at the loading disk screen. but this is the code i used for the 32:9 for animal crossing 40638e39

Ok, the code has been shortened by quite a bit. This means that a) it's less buggy b) it's more consistent c) the OoT version is almost done as well.



EDIT:

Aaaaand here it is. Master Quest is up first. It mostly behaves the exact same way, so that's cool when trying to port the code.



EDIT 2:

And Ocarina of Time - Regular Quest as well, including some additional fixes you would need:



Ocarina of Time - Collector's Edition is up next.

All codes have their game version protection included (so the code won't run if it is the wrong game version, for safety) and the levitation codes have been updated to only be usable in third-person mode.

EDIT 3:

And to conclude the series with Ocarina of Time for the Collector's Edition:



I have a few more idea's to work on, such as being able to keep Potions and Milk after playing the Song of Time, quick swapping transformation masks with the X, Y and Z buttons and a second set of item buttons. Not everything worked out so well so far, where the second set of item buttons proved to be the most troublesome.

Hi Admentus, sorry for the offtopic little, but do you have any general strategy (or is there any at all) how to turn Gecko code to AR?

For any advice thanks as always

Both AR and Gecko refer to the same RAM addresses. AR just uses different code types than Gecko. The code type is indicated by the first two digits of the address. Normally each RAM code addresses starts with 80 or 81. For addresses in the 81 space, just increment the code type by 1.

There isn't anything inherently wrong with AR or Gecko. Both have their own advantages and disadvantages. I mostly prefer AR, since that is what I am the most familiar with. Searching for addresses with Dolphin usually refers to AR, but as said by changing the code type and adding it in the Gecko section you can make an Gecko Code out of it, and vice versa.

Dolphin has a fairly in-depth guide on AR: https://github.com/dolphin-emu/dolphin/wiki/GameCube-Action-Replay-Code-Types. 

For example, An 8-bit multi-line "while not equal, turn of all codes" conditional is indicated by C8 (or C9 for addresses in the 81 space) when using AR. I am not entirely sure Gecko supports the same conditional. However Gecko has for example the "On/Off Switch" which is assigned through the code line CC000000 00000000.

For example:


This toggles between the value 0 and 1 for 8-bit address 80002FC2 each time D-Pad Up is pressed.

There is an extensive code type guide on Gecko at: https://geckocodes.org/index.php?arsenal=1.

Make sure when trying to convert between AR and Gecko that your current functions and conditionals are supported in the other. Any issues that Dolphin previously had with Gecko seems to have been resolved by now. As long you keep to the latest development builds.

Simple writes are easy in both AR and Gecko. Both refer to the same code types. 00 or 01 for 8-bit writes, 02 or 03 for 16-bit writes and 04 or 05 for 32-bit writes. Nothing you need to change if all you are using are writes. Simple "if" conditional require some change. Gecko uses code type 28 or 29 for a 16-bit if while AR uses code type 0A or 0B for a 16-bit if. Actually... I am not even sure if Gecko supports an 8-bit "if". Gecko has great support for pointers through, which (confession time) I still completely suck at, which is also one of the reasons I stick to AR... For now... Most of the stuff I want to attempt works well enough with AR.

Personally I really love AR for their support with multi-line conditionals. Apply 00000000 40000000 each time you want to end the multi-line conditionals. It makes a lot of the magic possible. Well... I suppose it could be better. AR lacks a toggle function like mentioned for Gecko, which is onee of the reasons why some of the codes are partially (multi-part codes) in Gecko.

Now GameShark... That's completely horrible. I think it would be completely impossible to attempt to port the majority of the AR code I have worked on.

Thanks for your your explanation

I wanna learn how to convert some of the Gecko codes to AR because from there I kinda already know where to search for some other possible codes and addresses.

I was lucky enough to find many things from around the addresses and old codes that One More Try showed me, when he was still around. So now I want convert some of his Gecko codes and then look around there.

Another fun code, just because I can make it happen.


Ocarina of Time versions for both D43E01 and PZLE01 are up next.

What does the code exactly do? Great you asked! By pressing the C-Up button on the Ocarina of Time or the Longshot you can downgrade it back to the first tier (aka, Fairy Ocarina or Hookshot). Don't want it anymore? Great! Just press the C-Up on the proper item icon again and you get your second tier item back again. Can you cheat with it? No, you can not. You require to have obtained the Ocarina of Time or Longshot prior before you can swap them all day long.

On a side note, downgrading to the Fairy Ocarina no longer makes you able to play the Song of Time... Since it isn't the Ocarina of Time. Doh. If you want to play the Song of Time as usual, just switch back to the Ocarina of Time again.

How how does this magic work? Does the game actually remember you had the second tier items before? Nope. But I can make that happen anyway, but making using of some unused variables which gets saved when saving the game. I pretty much used the ammunition storage for the Fire Arrow and Din's Fire... Except both items don't have ammunition values (magic arrows refer to the ammunition of the Fairy Bow). Similar trick I used for Majora's Mask before.

Does Majora's Mask need a version of this code as well? Nope, since Masks and Items are a single tier only. No upgrades, except for the Quest Status screen stuff (swords, shields, quivers, bags, etc). And uhh... I already covered switching between Swords and Shields before.

Ohh well... That didn't take long.


EDIT:

And the final version as well for the Collector's Edition:

More stuff and fixes, and more is coming:

Majora's Mask








Ocarina of Time - Master Quest








Ocarina of Time - Regular Quest








Ocarina of Time - Collector's Edition








EDIT:
Fixed some types for the "Set Item In B Button With A On Icon" for Ocarina of Time - Master Quest (D43E01) and Ocarina of Time - Regular Quest (D43E01). Also finally added codes for Ocarina of Time - Collector's Edition (PZLE01).

Who's ready for some insanity? Laws of gaming are about to be broken and shattered.


200 lines of code. BAM!

Ok... Seriously... What does the code exactly do? It allows you to keep potions, milk and fairies you stored in each of your six bottles after playing the Song of Time. Potions include the Red, Green and Blue potions and Milk covers all three variants of milk.

So how does it work? Similarly as with previous codes, there are some unused variables that get permanently stored when saving. These variable bytes gets assigned with a copy ID of the bottle's content. Loading a save file can do two things: load with everything intact from a Owl Statue or start back at the first day in front of the Clock Tower. The idea is when Link starts back at the front of the Clock Tower on the first day to restore the bottle contents from those variables I mentioned earlier. The message that displays the amount of hours you have left seems to be localized within an unique map instance environment, so that will serve as an indicator when to restore those bottles. As a side note to prevent issues (at least for now), empty bottles (since going back in time empties each bottle) kept on C-buttons will be removed, so you have to assign those again.

Hopefully it's bugfree.
