@Anutim

EDIT: Gif added. Code has been modified. I forgot to add the portion that copies the current player data to the "stored CSS info" location every frame while on the CSS. An example of why this is useful:

Say P1 and P2 play a match, then return to the CSS. P2's port gets closed and P3 opens and chooses a character. At this point, if you exit out of the CSS and back into the menus, then return to the CSS, P1 and P2 will still be active and it will "forget" that P2 was closed and P3 ever was trying to be in the next match because that current CSS player info was never saved. (It saves when you press Start to go to the SSS). So the addition to the code above stores the current player info every frame when on the CSS so it always "remembers".

HMN Always Available on CSS (v1.02) [Dan Salvato]

04260508 38000003
04261adc 38060000

Sup! This is my spin on spoofing controller plugins. Unplugging the controller still makes the hand disappear, and it will auto-press Start on the results screen if a controller is not plugged in. However, opening a character slot still gives you the HMN option, and unplugging a controller doesn't auto-set the slot to CPU.

So, this allows you to set slots to HMN while having the game still understand that no controller is plugged into that port.
Enjoy!

Disable Trophy Messages
0415d984 4e800020

Unlock All-Star Mode, Random Select, Sound Test, Score Display, and Every Special Message

• Special Messages never appear (because this code makes you already have them all)
• Only takes affect after a load sequence (such as navigating through the Start Screen)

0415d94c 4e800020


So...because the above code only gets executed during a load sequence, if you boot to CSS, you will not have these things unlocked immediately. To fix this, before booting to the CSS, let's branch to the "update unlocks" function that the above code modifies, which will give us all these features right away (if the above code is enabled as well).

Combine all three of these codes to have no messages ever appear and to have all features unlocked upon boot. Let me know if anything doesn't work, but it looks to be good on Dolphin.

Would it be simple to make this not load memory card data (and skip the memory card prompts)?

It's an ASM function that ends in a branch link return, so you can just C2 inject it.

All I did was copy Jorgasms' DOL mod content, add a line at the bottom that ends in a "00000000" to tell the codehandler it is the end of the function, and then add the header line (first half is C2+RAM inject offset, second half is how many lines down from the header until the end of the code).

[Dan Salvato]

Can anyone explain this instruction? Everything I've read about it goes straight over my head.

rlwinm. r15,r7,0,29,29

This is all you need to know. The instruction takes the value in r7 and applies a "mask", and stores it to r15. The mask values are as follows:

Mask                Value
---------------------------
31                 00000001
30                 00000002
29                 00000004
28                 00000008
27                 00000010
26                 00000020
25                 00000040
24                 00000080
23                 00000100
...
01                 40000000
00                 80000000

The point of this is to process data stored on a bit level, usually controller inputs. For instance, if A is 00000010 and B is 00000020, then if you press A+B you get 00000030. So, you can't use a standard cmpwi 0x10, because that would only work if you're ONLY pressing A. Instead you use rlwinm r15,r7,0,27,27 which will check for the "00000010" bit and, if found, will set r15 to 00000010. If not found, r15 will be 00000000. I believe the period at the end of rlwinm will automatically compare the result to 0. So, your typical code may look like this:

rlwinm. r15,r7,0,29,29    #does r7 contain the bit 00000004?
bne DOSTUFF    #if so, branch to DOSTUFF

The mask numbers seem arbitrary, but you're actually specifying the bit number in a 32-bit word. For instance, 31 means the 31st bit from the left (starting from bit 0), which is why it's 00000001. Bit 30 is 000000...0000010 in binary, and 00000002 in hex. Etc.

The period at the end of rlwinm automatically compares.

Have the 20XX CPU AI modification codes been posted in this thread somewhere? If yes and anyone knows where, could they link it? Otherwise, I'll check through and see if I can find it. I just don't want to go through 30+ pages of content looking for something that isn't there. I remember reading about the random throw DI stuff somewhere, but I don't remember what thread.

I just don't want to go through 30+ pages of content looking for something that isn't there. I remember reading about the random throw DI stuff somewhere, but I don't remember what thread.

On mobile but stratacoaster and Achilles wrote a gecko code for it. just look through strat's topics on his profile page

Could

Unlock All Characters and Stages (1.02)
0445BF28 FFFFFFFF
0445BF2C FFFFFFFF

be replaced with

Unlock All Characters and Stages (1.02)
0045BF28 000F00FF

?

"Random Spots" on CSS Always Pick ?? (1.02) [Jorgasms]

0425fb74 386000??

#Replaces branch and link to the random function to li r3, 0x?? where r3 holds the
#CSS icons from top left to bottom right, in order
#?? can be replaced with 0x0 - 0x18 (0-24) which represents the 25 character icons

I think I'll write a function that limits the characters available from random for practicing against CPUs so I don't have to worry about learning to tech chase a Pichu. Maybe idk.

You shall rue the day when a true Pichu main rises up and sets the 20XX standard.

Cool. I wrote the same code for CaptainJazz here, but just modified the line after the random function. Same difference. But I guess I’d consider yours better because the game will run through like 10 less code lines lol.

We have a new board, everyone!
Note the "Melee Codes" board in the Melee Workshop. Because we've been seeing so much activity, I thought it would be nice to have a better-organized home where resources are easier to access and codes are independently discussed/requested.

This thread will most likely be delegated to general discussion. I hope everyone makes good use of the new board.

I intend to try and put some of these codes on my wii - Would the GreenGreens Wind/Apples/Blocks disable codes work on both versions of green greens on 20xx (green greens on both screens)? I want to keep the Red GreenGreens stage texture but it doesn't have those things disabled for some reason.

Is putting these codes on my wii dangerous even if I follow the directions perfectly? Not asking for a guarantee, just want to know the risk.

Thanks guys, love the work here

Depending on how you add the GreenGreens code that disables stage hazards, it should work on both version of GreenGreens. Don't quote me on this, but I'm pretty sure Achilles just runs the code that removes these hazards when the stage on the second page is selected. Adding the code to the Start.DOL (or as you want run them in a .GCT file) would apply the code to both stages, as it would affect the game 'globally'.

Putting these codes on your Wii (or using an ISO with these codes injected into the game) isn't dangerous at all. The worst that would happen is your Wii soft-locks and buzzes at you, but if that happens just restart your Wii and you'll be fine. Best of luck, and ask if you need any help.

Unfortunately it definitely has to do with the stage texture and not the page.

Is that a method of adding gecko codes directly to the iso without using the method in the first post? Is there a tutorial for that somewhere?

I think I've seen this actually. 1 in 3,000 (I think those are the numbers) Mr.Saturns explode upon impact in vMelee.

Why?

It frees up a Special Melee game mode.

At any in-game function...

Is it possible to use gecko codes with the 20xx hack pack (loading through usb and nintendont)? Is there a guide for that somewhere? I replaced the GALE01.gct file in "codes" with one I made in Ocarina but none of the codes I added worked

Just make them into DOL mods.

WHAT DO YOU THINK I AM SOME KIND OF CODING GOD

I looked through the Dol modding thread and tried my hand at implementing the simple "Pichu doesn't hurt herself" code but didn't make much progress.

I wrote a guide on how to convert 04XXXXXX (Gecko) codes here: http://smashboards.com/threads/the-dol-mod-topic.326347/page-10#post-18789228
And Sham Rock has a guide for C2XXXXXX (ASM) codes here: http://smashboards.com/threads/the-dol-mod-topic.326347/page-5#post-16623011

What does that end up doing?

 

[flieskiller]

Can it be possible to add more colors to the team color cycle? Like if you're in red team with Falcon, you can pick Red Falcon and Pink Falcon, or if you're Yoshi and you're in blue team, you can cycle to blue and light blue colors.

I'm sure the X and Y buttons still work because you can go set any custom skins in 20XX even if you're character is locked a certain color.

I'm having trouble getting mods working on Wii. I want to load Melee from a usb, but no matter what I do it always gives an error message and doesn't load. I have more than one game on my usb so is that a problem?

Depending on what method you are using, you need to make sure your games are saved correctly. Simply dragging and dropping an ISO onto your USB isn't going to work.

Are you using DIOS-MIOS, Nintendon't, or some third thing?
