Melee Gecko Codes + Guide and Discussion

[jacob91]

Hey, uhh, the SSBM Code Tools download link in the OP is dead, where might I find an alternate download link?

 

[PKRev]

@Dan Salvato Hey! I used an online GCT creator so i can use the taunt battle gecko code but when i put the code in it said "there is no such code." Plz help.

You have to use the GCTEditor, which can be found here, note that this requires installing java for it to work.

Is there a guide on how to use this program? Or can you tell me how to use this plz?

Alright, here I go!
1. Download the program
2. Install Java if you haven't already
3. Open up Notepad
4. On line 1 of your notepad, Copy and Paste

"Super Smash Bros. Melee

Version 1.2"

In that exact format (don't include the quotation marks)
5. Create a line from "Version 1.2" and then proceed to put all of your codes on the notepad.
6. Save the notepad, and call it "GALE01.txt"
7. Open up GCTEditor
8. From the GCTEditor, open up the GALE01.txt
9. From there, click "Export" (Make sure not to click any of the recommended codes, those are for Brawl)
10. Once at the Export screen, type in "GALE01"
11. Press save
12. Proceed to insert your newly created .gct into it's intended location
13. Enjoy having just created your own .gct independently of geckocodes.org!

Anyone have the code "Press Z to change character to SoPo/wireframes/giga bowser/Sheik" like in 20xx training pack?

achilles made a thread about it I believe. and theres point buried in the hacks thread about it.

I'm curious about this as well if there's anything out there about it - hacks thread meaning melee, hacks and you? I'm probably searching the wrong phrases...

I've extracted that code from 20XX 3.0.2, I'm sure the most recent version would have a better code (he said he improved most codes), but it does the job. Code in the spoiler.

Achilles1515 , what do you think of this as an option in 20XX? I wonder if it should even be enabled by default. Considering the technical details of vanilla turning (basically that even identical inputs can result in different animations), the normal turn mechanic seems kinda like a milder Brawl tripping, and it just seems like a bad/unintentional design flaw IMO.

I'll never enable it by default in 20XX because it is not vanilla in any SSBM version. Albeit a stupid mechanic, it is what it is. I love the analogy. These are both great codes by Magus and I do plan on putting them both in 20XX as options. I still need to make that damn "Mechanics Codes" Debug Menu page...

Where are the RRGGBB values for the Blue costume for the Marth sword swing colors code? I noticed that the values marked RRGGBB change the color of the inner sword swing. Is it possible to change both colors, or do they get the outer sword swing color from the values shown in the Changing Color Effects thread?

Edit: After some testing, I found that for some reason, the code for costume dependent sword swing colors will stop working if the Sword Swing value in PIMs.dat (from the Changing Color Effects thread) has been changed.

Hey,
So I'm trying to use the Gecko Codes in the Netplay Build to play online and its just blank. If I try and download the codes, it just errors. If I use the new 20xx (beta 4, thanks achilles), and my 1.02 iso, they both allow me to use codes, but the Netplay Build wont. What do I do?

 

[maxwood38]

Wait, I seem to have fixed it by copying the codes from the notepad file of 20xx into the community build notepad. Not sure if it will work yet, but I haven't seen this anywhere online before.

 

[SinsOfApathy]

Wouldn't recommend it, since Netplay build has pre-existing DOL edits. Same with 20XX.

The only reason 20XX has codes shown is because it uses the vanilla Melee 1.02 game ID, while Netplay Community Build does not.

ok so this didn't work, and I see that a lot of people are having this problem on the smashladder chats and stuff. I have the right ISO, and version Dolphin and setup, But no codes. I saw that someone else said their version of dolphin didnt come with codes, so how do I fix this for the Netplay Version (which runs fastest for me)?

Remember, Melee 1.02 ≠ Melee Netplay Community Build.

Any guides for setting up netplay in general will assume you want to use a Melee 1.02 ISO. These guides don't don't really 'overlap' for the Community Build; there are extra steps that can be ignored. If you're wanting to use a Melee 1.02 ISO, you will need to go to the Gecko Codes tab and check 'Netplay Community Settings'. If you're using the Community Build, which is a completely different ISO, you don't need any codes since they are already injected into the ISO itself.

Again, If you're using the Melee Netplay Community Build, you don't need to have any AR codes or Gecko codes whatsoever. There aren't any codes that are supposed to show up anyway.

How do you get around the caching issue? I have the "Flush Cache on Scene Change" code enabled but I still can't get Dolphin to hit my break point every time/ run my injected function every time.

[ssknight7]

Achilles1515 or anyone else, is there a simple way I can insert a delay into falco's short hop laser function in 20XX?

I'd like to slow down the rapidity with which falco short hop lasers. Is there a way to tell it to only perform the short hop laser every 1 second or every 2 seconds or something? I know this would be a gecko code, I tried to isolate the part of 20xx that is responsible for the short hop laser but not enough free time to track it down

I’m not sure exactly what you mean, and need to know the context of your code and the manner in which you are conditionally executing it.

Not sure if this helps or not –

Maybe. But that code is such a pile of sh*t that I never want to do anything with it again. The new Falco AI lasers well. You'll like it.

Dolphin automatically invalidates the icache when it patches in Gecko codes, and if a code is patched in through a different method, like Dolphin, it checks that case and the HLE invalidates the icache.

https://github.com/dolphin-emu/dolphin/blob/master/Source/Core/Core/GeckoCode.cpp#L146
https://github.com/dolphin-emu/dolphin/blob/master/Source/Core/Core/HLE/HLE_Misc.cpp#L42

If you're running into an issue, your function may be running during an OSDisableInterrupts. I've seen a few functions that would only run at seemingly random times, until I moved it past the point where interrupts where re-enabled. I do not know why this is the case.

Stalled damage used for knockback (1.02) [flieskiller]

Instead of using the full damage for knockback, it's the stalled damage instead (move damage is used in the formula for knockback).

Do you mean, like, damage from stale moves instead of the damage the move would've dealt non-stale? Cause I thought the formula was based on damage dealt already.

Or are you talking about moves that initially have set KB?

I'm sure the game always used base damage for knockback. In that function where it calculates the knockback, it used a non-decimal number of the damage of the attack. It then multiplies that attack's damage with the % of the player. Setting the line of my code to always being 0 only uses base knockback for attacks. My code loads directly the stalled damage instead of the base damage (that comes from a substraction)

So, in a way, this makes the game actually take staleness into account, thus making the strength loss more noticeable?

not more noticeable, it changes something now.if you up-smash a Puff to arrive at 100% on FD, it would die fast. But with the staleness included at maximum (10 stales from the stale table), I'm sure it wouldn't kill because the move would hit at around half damage (9%), which would be similar to the bair in term of knockback

Yeah, kind ew, it would make the game kinda different. Falco shining makes the enemy go lower each shine, it's something worth trying. It makes Fox OP because he can unstall his moves with his lasers

Hey, I've been getting into Gecko codewriting lately, and it's really interesting. Anyways, I'd like to get into writing more codes (other than just memory edits) by using breakpoints but it requires compiled Dolphin, which I cannot get. I'm running Mac OS X and I'd like to know how to compile Dolphin so I can create breakpoints. If someone could help me out I'd be grateful.

Edit: I found this bugfix instructions for compiling it with ffmpeg:

https://bugs.dolphin-emu.org/issues/7933

I also found a thread for DebugFast dolphin and how to do it on Mac, so I combined both to get 3.5 Dolphin DebugFast in attempt to get breakpoints. But, it didn't work. Can someone help me out?

Edit 2: I realized you actually can set breakpoints within the Memory and Code tabs, but now whenever I set a memory breakpoint the game freezes until I take off the breakpoint, in which it can be resumed by pressing Play. The thing is, I'm aware the game pauses (by pause i mean through emulator) when it hits a breakpoint, but the game freezes when the breakpoint hasn't even been hit. Also, gameplay in general is really slow. If someone could help me out with this new issue I would be grateful.

Hey! Awesome to see you picking this up!

It sounds like you got debugFast working; which despite its name is actually very slow. You'll usually see a huge FPS drop while using debugFast, and it's normal.

The freezing that you're describing sounds like you might be confusing Memory Checks with Breakpoints? They're blue and red, respectively; and are assigned by either going to the memory or code tabs like you mentioned. You can actually use regular old breakpoints in the normal version of Dolphin; it's memory checks that are unique to the compiled version iirc.

If you set a (blue) memory check in the memory tab, it will pause the code at a place that reads/writes to/from that memory address. If you're seeing something constantly freeze after setting a memory check, remember that it's the code that is pausing; so look where the code has stopped in the code tab to see if it's simply a popular memory address that keeps getting read/written to by something(s)

Also, sometimes after setting a (red) breakpoint you'll have to step over it with the "step" button in order to get past it. I'm not quite sure why this happens; but the step button has been my workaround for ages.

Hope that helps~

 

[omegagmaster]

Hi,

It seems that the reason why it is freezing is because of the fact that the address is being read. Is there any way to configure the breakpoint so that it doesn't pause when it is read? Because under the "Breakpoints" tab, there are no configure options for some reason. Also, the memory address I'm interested in at the moment is 80C6DBA4, and the instruction that the game freezes at is shown as the following:

lwz r0, 0x0024 (sp)

which I know is "load word" in ASM, which means that it's probably reading address 80C6DBA4.

It seems that the reason why it is freezing is because of the fact that the address is being read. Is there any way to configure the breakpoint so that it doesn't pause when it is read? Because under the "Breakpoints" tab, there are no configure options for some reason. Also, the memory address I'm interested in at the moment is 80C6DBA4, and the instruction that the game freezes at is shown as the following:

lwz r0, 0x0024 (sp)

which I know is "load word" in ASM, which means that it's probably reading address 80C6DBA4.

From what I can tell, that memory address appears to be something dynamically allocated. I’m not going to be able to get a clear picture of exactly what you’re looking at without a bit more info about where it came from. Are you looking at player entity data or something like that? Did it come from a function, or did you look it up through pointers?

That load it’s stopping at appears to be from a stack operation, so it’s likely a part of a function epilogue that collapses a stack frame. What’s the address of the instruction?

It clobbers r0, so you might want to check the contents of r0 before that instruction gets read. If it’s related to what you’re looking for, then you might want to look into whatever loaded that value.

There’s a way to specify a few options for memory checks in the breakpoints tab by clicking the +MC button and adjusting settings from the GUI that appears. It looks like this on my setup:
