Dolphin, the GameCube and Wii emulator - Forums

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:

Code:

28134C58 00000008
00002FC2 00000000
CC000000 00000001
00002FC2 00000001

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.

Dammit, it's tough.
hmm, and how the AR version of this code would look like for example?

C2AFF884 00000003 //Offplay Flag
7FC3F378 3A400001
C042FFF4 D042FFF0
60000000 00000000

If its too much work or anything, just say a word, I dont wanna bother you with this anymore
Thanks...

Nah, it's fine. I do what I can. Or least, to how far my limits go.

Ok, so the following code is in Gecko if I am correctly.

C2AFF884 00000003  // Line 1
7FC3F378 3A400001  // Line 2
C042FFF4 D042FFF0  // Line 3
60000000 00000000  // Line 4

Line 1 is codetype C2
Line 2 is codetype 7F
Line 3 is codetype C0
Line 4 is special codetype, since it does not refer to a ram address?

What does each line's codetype mean?

Line 1 - C2: Insert ASM
Line 2 - 7F: I don't know
Line 3 - C0: Execute ASM, except it's not?
Line 4: ASM code fills all the line

Sadly, ASM is involved here. And I am not sure if Action Replay (AR) even supports that. The code you posted does not just write and check to the RAM. I never really worked with Gecko other than the On/Off Switch functionality, so I am not sure how to convert it to AR.

Any reason why you would want your code to be particular converted to AR?

well, some time ago I get this code from One More Try.
As it is its kinda buggy, so I cant really use it, unfortunately. 

I already found the AR code that affects goalies, so that is good, but can't find as AR that other part that affects only "OFF PLAY ANIMATIONS".

This is how it all looks as Gecko.

Hey so i found a way to get 32:9 aspect ratio to work for Master Quest on NTSC-U!
Using the widescreen hack and stretch to screen plus this AR code:
AR Code Widescreen Render Fix for 48:9 Aspect Ratio on TLOZ Ocarina of Time / Master Quest[/color]
04136840 C0B40000

It fixed any culling issues while keeping it at my aspect ratio, it may not be a perfect solution but it works!

found here: https://forums.dolphin-emu.org/archive/index.php?thread-44089-6.html

Ok ok... My fault... I forgot to include Stone Tower and it's inverted version in the check.


EDIT 1: Fixed an issue with using the Ocarina's secondary button when in the Pause Menu.
EDIT 2: Fixed an issue with the code not working within the Inverted Stone Tower Temple.

I found some interesting additions for Ocarina of Time recently


Yup. This means you can have a permanent button for the Fairy Ocarina or Ocarina of Time. I should port this to the other versions soon, and preferably for Majora's Mask as well.

Also, I finally managed to find a solution for the Quick Boots Swap code. Here are some of the RAM addresses I have to account for in the code:


The code will be updated soon.

This is it!


The code should now properly account for adjusting the speed and animation values when switching between boots. Equiping the Iron Boots while swimming is also accounted for!



EDIT:
Got one for Majora's Mask as well!

One more code for Majora's Mask!


And I ended up changing another code yet again...

This is extremely epic!

This code basically restores the original credits scene to be the in-game engine rather than the prerendered video. Ozidual's GC2N64 Restoration Patch also restored this, but now you can restore the credits without patching your disc. Other versions of course will also be ported.

Continuing where I left of. Haven't tested the Credits Fix code yet, but the values do match


EDIT 1: Included Play Ocarina With D-Pad Right code.
EDIT 2: Included Equip Boots With L + D-Pad code.
EDIT 3: Fixed turning speed bug for the Equip Boots With L + D-Pad code (both versions of D43E01, check 3 posts back for updated MQ code).
EDIT 4: Sorry my bad, the Play Ocarina With D-Pad Right code was from the MQ version.
EDIT 5: Unbelievable... I keep messing up the Play Ocarina With D-Pad Right code. It should be correct now hopefully for real.
