To use your disk, you must use Project M Launcher.
Gecko wouldn't work.
If you want to do USB loading, follow the instruction of M22k.
I don't like to talk about USB loading.

It should work, I think.

Yeah, you can use your 16gb card.
I'm not sure what you mean by second question, but I think there isn't anything that works with normal SD but not with SDHC.

That's strange...
You have to put files into private/wii/app/RSBE/pf if you are using normal FPC.

@ToadKart
This works with any code set. Brawl-, or whatever you want to run.
This works with hackless wii, but you have to find out some way to run the launcher.
smashstack with normal SD->switch to SDHC, or letterbomb with SDHC

@shadowXtreme
See what Mewtwo2000 says.

@Don Jon Bravo
Yes, you're right. As for AXNextFrame, iirc you can though I'm not sure.

@Shun_One
Yeah, this needs Project M Launcher but you don't have to launch Project M.
You can even launch Brawl- with it.

@Jade_Rock
No, because Gecko switches IOS to 38, which doesn't support SDHC.
Project M Launcher does the almost same thing as Gecko except for IOS switching.

@Mewtwo2000
I meant you couldn't use contents in USB. i.e., you cannot read pf folder in USB.

Yeah, you can.
So FPC3.5.1+RSBE+SDHC extension+Project M Launcher will replace both Gecko and Riivolution.
Though this doesn't support USB devices.

Now Project M 3.01 is out, so I release this:

This code allows you to use SDHC cards with FPC 3.5.1.
Gecko speed+Riivolution SDHC support=SDHC extension

Requirement:
*SD or SDHC cards(SDXC cards don't work)
*System menu above 4.1(if you have IOS58 installed, it's OK)
*Project M Launcher

Usage:
1. Make GCT with FPC3.5.1 and this code
2. Run Project M Launcher
3. Enjoy!

NOTE:
If you experience freeze when you try to reinsert SDHC, please try to return to main menu before you reinsert SDHC, and then enter CSS.

Mmm... It works while the game is loaded with a proper IOS, no need to use the Project M launcher specifically...

I mean, Bero, you've said this doesn't support USB devices, but I'm using it on a USB device since the day you created it. Both "USB Loader CFG" and "USB Loader GX" work for me, with either the hermes cIOS based in IOS 57 (on IOS 222/223) or the d2x cIOS (on IOS 249/250).

Just in case somebody cares, Project M includes this code since version 3.0. That's why some people were able to run Project M from USB loaders with a SDHC. It'd had been impossible without this code.

The new Project M laucher is the easiest way to use the SDHC card with an actual Brawl disc though.

I included small debug codeset in AIScriptpad zip.
Visualizer code is this:
Training Mode AI Super Debuggah ALPA v0.1xgt [Dantarion]

Go to training mode and turn on information window. One of them shows current executing routine.

They are defined in Routines.h.
Routines which start with "Unk" are unknown. But using Dantarion's visualizer code, you may figure out something.

AI works on every stage if it is coded properly.
Is this answering your question?

I think yes.
If I remember correctly, the label number was 2.

@E-scope12
Could you explain what you mean by "stage" more specifically?

@sluigi123
I would find the position where Fox uses up B and write like this:
if var0 > 0.5
    var0=0.5
elif var0 < 0.3
    var0=0.3
endif
if var1 > 0.5
    var1=0.5
elif var1 < 0.3
    var1=0.3
endif
AbsStick var0 var1

I'm not sure if I answered your question though.

Please use AIScriptpad2.0. Rebuilder of BrawlBox is made by me and it contains bugs.

First, create project specifying common3. It automatically exports scripts into source folder.
Then, create project of squirtle and copy 2040.as from common3 source folder and paste it in squirtle's source folder. Then, press Tool->Full build and squirtle's pac file is built in "Build" folder.

EDIT:
Squirtle's pac file is FitPokeZenigameMotionEtc.pac

@NEWB
Squirtle doesn't overrides default recovery AI so you have to take 2040 from common3 and paste it in Squirtle's source folder. Then, you can edit it as you'd like.

@Albafika
The language is easy to understand so you may not waste so much time

@Kneato
It works like other programming language. * means "multiply" so "var14*=-1" means "change sign of var14".

A.
1. AIMain file is located in FitChar(Motion)Etc/FitCharEtc/ai_char/MiscData[2].
BJ's BrawlBox displays it as "CE", which is a name based on my misunderstanding 2 years ago.

2. You can find Fighter.pac in Disc/fighter/Fighter.pac. Fighter.pac is also buried in common3 so editing Fighter.pac is the same thing as editing common3. File Patch Code cannot load Disc/fighter/Fighter.pac and you will have to edit common3 if you would like to change overall AI behavior.

Further questions are of course OK.
