Hacking Forwarder with meta.xml support

FIX94 · Jan 6, 2011

Hey guys, some people want to have the source from my cfg-loader forwarder, so here it is

I hope it's OK to open a new thread for this...

This is the source from my Official Configurable USB Loader Forwarder v12!
No splash version:
forwarder_no_splash_v12.7z
forwarder_no_splash_v12_no_args.7z

splash version:
forwarder_splash_v12.7z
forwarder_splash_v12_no_args.7z

Everything you will need to compile it properly:

Libogc:
http://www.mediafire...xjko49x66q22jsb
Libfat:
http://www.mediafire...d99sva9i899c45b
Libntfs:
http://www.mediafire...8rbjzwtac0rngc4
Libext2fs:
http://www.mediafire...ki1axm7zuiacu87
Portlibs:
http://www.mediafire...312e4o9c57m503s

You will also need devkitppc r22/23/24 for this. devkitppc r25 and r25-1 doesnt work properly with it, so use a older one.

Features:

-NTFS, FAT32, ext2,ext3 and ext4 partition support
-IOS58 for USB 2.0 speed
-Can load from USB and SD
-Can load dol, dollz and elf files
-meta.xml arguments support
-supports 3TB+ HDD
-Using WiiXplorer forwarder base

Ext2, ext3, ext4 and NTFS partition rules:
If the loading path is set to "apps/usbloader", it must be in this folder. It doesn't work for example if the file is in "apps/USBLoader".
Folder and Files must have execute or read permissions for everyone, otherwise the forwarder will return to system menu.

Whats the differences between your forwarder and Narolez NForwarder 58?

The nforwarder is using a splash screen and the NTFS support doesn't work with it, you will also need the older devkitppc r21.
This forwarder don't use a splash screen, NTFS support works and you can use meta.xml arguments, the new devkitppc r22 will also work with it.

FIX94, glad to see you starting your own thread for this! I know you put a lot of work into it! Good job!

I have a request though, can you also share the source code for your forwarder that does include a splash screen (I know u got it kicking around somewhere!)?

Also, does v7 speed up the loading time from SD Cards? Or is that planned for v8?

Thx again!

stupid Q : can this be used to make a mighty channel forwarder dol with meta support

LocoRoco · Jan 6, 2011

Thank you

Would be great if you write more info for the not so smart peeps (me)

have an issue it comes out with fileop.c:14:18 fatal error ntfs.h no such file directory

what did i miss

Skater4599 · Jan 6, 2011

Thanks Fix94 for doing this, I didnt know you already made one with argumetns from meta.xml! I was going to take a look into this for Mighty Channels, saved me some work

nice work man.

@Fox888 - I'm at work now so I can't compile here but if nobody has done it when i get home later.. I'll compile this for Mighty Channels and put it into the channels floating around in that thread and post them

Hi,
I have installed the .WAD file (I haven't downloaded and messed with the source, sorry - I don't know much about compiling code). Can you tell me what the default path that Configurable USB Loader should be? At the moment, I have it on my SD card as E:\apps\USBLoader
Is this incorrect?

Thanks
I

You need the to copy the contents from the libntfs file into the libogc folder.
@ichirichi:
My forwarder is loading from apps/usbloader and apps/usbloader_cfg.
@Xflak:
It's planned and I will give it soon.
The source with splash will come soon.
@Fox888:
Yes!

ichirichi · Jan 6, 2011

Hm! in that case, I am doing something wrong!
It keeps returning to the Wii Channels screen whenever I try to run it.

1. I have the latest Configurable USB loader installed and working from SD & HBC.
2. I placed the v7 forwarder WAD file in the a folder called WAD on the SD card.
3. I ran WAD Manager v1.7.
4. Accepted disclaimer.
5. selected IOs 249
6. Selected "disable" when asked to choose NAND emulator device (I am not sure if this is right).
7. Selected SD as source for WAD
8. Located the WAD and installed it.
9. Restarted.

The location of the Configurable USB Loader is in apps\usbloader.

What am I doing wrong please?

Fox888 · Jan 6, 2011

Skater4599 thank you so much

Fix94 thank you so much for sharing this

XFlak · Jan 6, 2011

Sounds good FIX94!

FYI, FGR already used this code to build a mighty channels forwarder channel

You need IOS58, get it here:

Cheers FIX94. Will try it later! Keep up the great work

I take a fast look into source and found this bad code (possible buffer overflow):

Code:

ÂÂÂÂchar meta_path[200];
ÂÂÂÂstrcpy(meta_path, exe_path);

better:

Code:

ÂÂÂÂchar meta_path[200];
ÂÂÂÂstrncpy(meta_path,sizeof(meta_path)-20, exe_path); // 20 bytes reserved for modifications

you can also rewrite the whole block to use the whole buffer without overrun (untested!):

Code:

void load_meta( const char *exe_path)
{
ÂÂÂÂchar meta_path[200];
ÂÂÂÂconst char *p;
ÂÂÂÂstruct stat st;

ÂÂÂÂp = strrchr(exe_path, '/');
ÂÂÂÂsnprintf( meta_path, sizeof(meta_path), "%.*smeta.xml",
ÂÂÂÂÂÂÂÂp ? p-exe_path+1 : 0, exe_path );
ÂÂÂÂÂÂÂÂ
ÂÂÂÂif (stat(meta_path, &st) != 0) {
ÂÂÂÂ....
}

Hey Wiimm, THANKS for looking in the code, I'm not a coder so I can't fix things like that. I will try it out later!

Then let me explain "%.*s" (I know that many developers doesn't know/use this and write sometimes very complex code instead):
It's a string conversion. "%.21s" means to copy maximal 21 chars. Replacing the number with '*' means: take this int number from argument list. This int argument must be placed before the string.

Yes, this would be better! I've also uploaded a new forwarder version, it's untested but it would be great if someone could try it out!
