Melee Gecko Codes + Guide and Discussion

[Achilles1515]

Bought a Gecko SE clone called the Shuriken today, so I'll be able to do debugging with not-so-**** software on a real console!

http://www.staffs2.webspace.virginmedia.com/shuriken_usb.htm

Costs about $30 in the U.S.. Heard back from the creator an hour ago that mine is ready to ship between Thursday and Saturday.

Should I get one of these? What are the pros/cons over Dolphin? Can you somehow do save states on console with these things?

32 bits (endif, then) If not equal
224d4cac 20000000
044d4cac 20000000

About the name entry 8 letters by Dan, how do I translate the 22xxxxxx code into DOL? Do I have anything to do or simply keeping the 04 will work?

Should I get one of these? What are the pros/cons over Dolphin? Can you somehow do save states on console with these things?

Pros:
Better memory searching, which includes regex
Testing on actual hardware
Pointer search
Additional breakpoint conditions (You can break on a register.)
Stack trace, even if there's a crash

Cons:
Need to have the console physically located near you
Gecko's source claims some games don't pause, so it'll loop until it does. Don't know if that's actually true of any game though
Money

My reasoning for buying it was more or less because I'd like to see things on actual hardware without going through incredibly convoluted steps of moving an SD card and such. Plus, I'm trying to get access to the MMIO registers, so I can force an EXI or SI device to have different functionality, or as a means to send inputs to the console. Dolphin has no discernible way of doing that, and the Gecko might not either, but it's a step.

If you really wanted to, you can just use cmpwi, but those codes as gecko codes are mostly meant to make sure that you're not constantly writing stuff every frame, which may slow down the game and mess up your frame rate. When I turned that particular code into a DOL mod, I simply just did everything inside of the if block, which I believe is simply a memory override.
The offset into the DOL is different though for some of the name tag stuff. Usually you can get away with subtracting 80003420 for function addresses and 80003000 for data addresses to get the DOL address, but the name tag data is a different offset, for whatever reason.

You should probably use this for CSPs and what not, @ DRGN and anyone else!

EDIT:
Also affects some stage shadows which is cool. So it's the all-encompassing "camera shadow color", it seems.

That's pretty cool. Could the byte after the blue FF be alpha, or is that the white body shadow color?

What I've been doing (usually) is to go to Dreamland, and then orient the character by facing left or right so that the light source will make sense with the shadow that I add later for the finished CSP.

The variation in the offsets differences is due to the file being broken into different sections as it moves into RAM. Not all of the sections stay in the same order (though most do). There's a table in the beginning of the dol that describes the distribution. I can go into more detail later if you want. But for convenience I already have a function which converts RAM addresses to dol offsets and vice versa (can't remember if I mentioned that to you before already). I hope to release it soon.

It should be alpha, but when I tried changing it, nothing happened. Granted, I was trying to change it via a slightly different method than the code above, so changing it within the code might work. Haven't tried yet.

Does this allow save states on console somehow?

 

[SinsOfApathy]

Nope.

Edit: Word to the wise, don't use Nintendont's OSReport hook, at least with Melee. I'd enabled it thinking "All those OSReports used by the developer debugs would be nice." But nope, causes a freeze on startup. Then I kept running into issues with Nintendont getting stuck (or just taking forever to boot with it on), so I had to delete the ninconfig file and start it from scratch.

 

[zankyou]

Can anyone give some guidance on how to call and utilize the games functions. Say for instance if I wanted to play a sound effect. The function starts at 8038cff4 but I dont fully understand where to go from there.

lis r12,0x80ab
ori r12,r12,0xcdef
mtctr r12
bctrl

That branches to 0x80abcdef. Change to your desired line, of course.

So you'd set the registers it uses as parameters to whatever you want, then branch to 0x8038cff4. It will blr at the end of the sound effect function and return to your function.

Thanks for the super fast response. I really wish I knew about labels before.

Zankyou, so what's up, man? It's been a while. Have you been busy with school recently?

Zankyou, so what's up, man? It's been a while. Have you been busy with school recently?

Yeah. My harddrive crashed so I lost a lot of stuff and had to catch up on two major projects. Hard lesson learned in backing up stuff. But Im getting back into smash now.

Without knowing how the gamecube loads data/instructions into cache, it's hard to tell. Similarly, without any profiling tools, it's hard to tell how much the placement of code causes cache misses or slowdown.

It's possible there could be cache misses and there's no noticable slowdowns. I more commented on it so when we get to the point when there are noticable slowdowns, moving the code to a closer spot in the dol is something you could try to fix it.

Gamecube's 64KB 8-way associative L1 cache serves as a split 32kB instruction cache and a 32kB data cache. The 256KB L2 cache is entirely data cache, I believe. Melee's DOL is ~4.4kB by comparison. There's a little bit of overhead on that because of C pointer passing or C++ vtables (which I'm pretty sure Melee was C-based), and that's used almost entirely by stages and character files that should be loaded into the cache at stage load. That's why if you use a decompiler, you'll see an assload of instructions that don't get tagged, because they're "unused" until runtime.

I'm fairly certain there'd never be 8 associations of all ~5kB of instructions (Meaning the same instruction, 8 different places in the cache resulting in 8x5 kB), or you're doing something that'd have you legally wearing a helmet everywhere. So the reality is, unless you start doing things graphically (Magus's Debug comes to mind), which the Gamecube was sorely lacking on with its 162MHz GPU, you shouldn't run into issues here.

Sidenote:

Spoiler

Since the Gekko was 1-core (!1!!1!), there's no crazy bull**** done by developers/compilers like in modern consoles, where they just pin threads to the same core to abuse hardware behavior. The only time that's even close to done on a Gamecube/Wii is when the USB Gecko forces the game to freeze by using a while loop.

Dolphin doesn't emulate any cache behavior beyond the occasional icbi/icbz & sync. It will invalidate the icache occasionally, but it doesn't check at each JIT block otherwise it runs magnitudes slower.

As for Nintendont, Fix94 has stated that it's already pushing the Broadway processor, but it's doing kernel emulation, keeping fake MMIO registers, etc.. So, at worst you cause Nintendont to run like ****. Which frankly, it already does for me since I can't even use it with my Shuriken. It'll straight up freeze Nintendont or an emulated game if it's plugged in.

any advice?

The Gecko OS you use to load codes for Wii games? Yeah, not compatible with GC games iirc.

Correct me if I'm wrong.

You need to have a /codes/GALE01.gct file setup on your SD card. Your loader may just suck, or if you're using GeckoOS itself, I'd try a loader, like Wiiflow. I've had issues with GeckoOS during various things.

All I use is ISOs. Dios Mios plus Wii flow works. USB Loader GX is dog**** with DM.

Can anyone link or make a Gecko code to auto cancel any move? kind of like Turbo Mode in Project M but you can cancel it anytime.

Made this simple code to be able to use the training damage menu to test throw combos vs a lower player ID, since training always sets them as player 1 regardless of actual controller port that entered training mode.

Edit: Doesn't apply the damage setting when respawning, just when exiting the training menu. Now it does.

Disable Teams Mode Stock Steal

Start Button or A+B for Teams Mode Stock Steal
- Now allows for buffering this command.

By buffering I mean that if you hold A+B (or Start, but with this you still run the risk of pausing the game) during death animation, you will steal a stock as soon as possible. Let me know if anything doesn't work as expected.

On Gamecube, this code, if a player is dead and a living player pauses, the game crashes.

Take out the first three lines.

Take out the first three lines.

what the three 04 lines do? I understand they would make the game crash, but why are they modified?

 

[Achilles1515]

they are the lines for "buffering" the stock steal. It was experimental and turned out to cause freezes. I never bothered to look into it again.

Related to coins:

800d4ea8 = divide per 2, next two hex numbers make it round down
800d4eb0 = number set to give to the player
uses r4 for the function to store new number

Set number of coins back to 0 when dead (r4 = 0):
040d4eb0 3BE00000

do not lose coins when dead (mr r4, r0, which is player's current number of coins):
040d4eb0 7C040378

Timer is now shown in the bottom of the screen (1.02)

The last 4 numbers are the coordinates, so change the "b6" into something similar to have different height. Based on Achilles' PAL Stocks post.

I've finished part 1 of the system I want to place in my custom mode. Here is a bonus thing you can add in your game that will influence nothing, that can be fun to see.

Help by Achilles and inspiration from the Taunt Battle code from Dan Salvato.

Code below has been fixed so that a game is won by highest amount of stocks instead of most coins.

(edit: total screen height is different from Dolphin and console, and I didn't know that, so I increased the height a bit, from 41500000 to 41300000 for being able to see it on console with a TV)

(edit 2: Because of not enough testing, when a game was finished, the team with highest amount of coins was winning instead of the player with stocks left. I modified so that it was right for stock mode. Here is in the spoiler the old version with most coins winning the game:

Is it possible to use the NTSC codes on NTSC-J? I honestly don't think it is, but I cannot find NTSC-J codes for the life of me, so I'm hoping it works like that.
