Hacking [Wii] [vWii] libruntimeiospatch

[Excelsiior]

libruntimeiospatch (short: -lrip) is a library that provides all necessary functions for HW_AHBPROT (thanks to anyone involved in that). As of now all apps have their own code for that (IF they have), but I believe a library is better in this case, as on updates one does only need to update -lrip and re-link the Homebrews, rather than updating the code for every single Homebrew. (If you don't know what this is good for, you have no need for it)

Developers take all other infos from supplied API file.

It's part of the HomebrewFilter, so the source can be found in it's GIT repo (subfolder "libruntimeiospatch").

Installation:
runtimeiospatch.h => <DEVKITPPC>/libogc/include/
libruntimeiospatch.a => <DEVKITPPC>/libogc/lib/wii/

Download:
Source: http://downloads.nanolx.org/libruntimeiospatch
GIT: https://github.com/Nanolx/homebrewfilter

Changes:
1.5.3:
* changed layout of debug text to ensure it's always visible
* added colors to debug text
- cyan: headings
- green: patch succeeded
- red: patch failed

1.5.2:
* added SSL module patches made by FIX94 to fix some certificate
errors that occur when attempting to connect to a host using a
secure connection (DarkMatterCore)

1.5.1:
* code clean-up (JoostinOnline)
* add typedef for s32 (JoostinOnline)
* misc minor changes (JoostinOnline)

1.5:
* add ISFS_SetAttr() patches. (megazig)
Forces the ISFS_SetAttr() function to continue instead of
returning -102 when you're trying to change the UID/GID of a file.

So with this added to xyzzy and FS Toolbox, we can dump the untouched NAND directly after game exploit?

Not exactly. Xyzzy doesn't actually require these IOS patches to work, since we can just inherit full hardware access from the HBC and read the OTP and SEEPROM data (which is precisely what my unofficial version does). Quite easy.

And, well, there is already a FSToolbox mod, which was done by Excelsiior, too. And yes, it uses these patches.

 

[Skeet1983]

Does this do anything for Gecko OS? Was hoping for channel cheats in WiiWare/VC games...

 

[JoostinOnline]

You should update this.

 

[Excelsiior]

Oh, yeah forgot to update to 1.3 in first post... When I'm home later.

 

[officialjunk]

Has anyone tested this on either wii or vwii?

 

[Cyan]

yes, some homebrew are already using this library/souces v1.3, for example FSToolbox 0.4d, Settings Editor GUI 1.9.
Maybe other homebrew too, I didn't check others.

Maybe other homebrew too, I didn't check others.

Plus it is essentially the same code as has been in use in dozens of apps over the last year or two (since HW_AHBPROT support was added to HBC), pretty much all apps that previously relied on IOS patches but were updated to use HW_AHBPROT. This is just the same code externalized.

 

[Excelsiior]

HomebrewFilter, SaveGame Manager GX (vWii build), YAWMM DE are also using libruntimeiospatch. Updated first post for v1.3

As SifJar said it's nothing special at all, just library providing the functions, so that in case of an update only the library needs code changes rather than every single application. An app then just needs a rebuild (just as older apps need no more than a rebuild against new libogc for WM+ support).

 

[DarkMatterCore]

You should include this new patch (sorry, I still don't get used to SourceForge ):

const u8 isfs_setattr_pt1_old[] = { 0x42, 0xAB, 0xD0, 0x02, 0x20, 0x66 };
const u8 isfs_setattr_pt1_patch[] = { 0x42, 0xAB, 0xE0, 0x02, 0x20, 0x66 };
const u8 isfs_setattr_pt2_old[] = { 0x2D, 0x00, 0xD0, 0x02, 0x20, 0x66 };
const u8 isfs_setattr_pt2_patch[] = { 0x2D, 0x00, 0xE0, 0x02, 0x20, 0x66 };
 
s32 IosPatch_RUNTIME(bool wii, bool sciifii, bool vwii, bool verbose) {
 
    ...
 
    count += apply_patch("isfs_setattr_pt1", isfs_setattr_pt1_old, sizeof(isfs_setattr_pt1_old), isfs_setattr_pt1_patch, sizeof(isfs_setattr_pt1_patch), 0, verbose);
    count += apply_patch("isfs_setattr_pt2", isfs_setattr_pt2_old, sizeof(isfs_setattr_pt2_old), isfs_setattr_pt2_patch, sizeof(isfs_setattr_pt2_patch), 0, verbose);
 
    ...
}

It forces the ISFS_SetAttr() function to continue instead of returning -102 when you're trying to change the UID/GID of a file. It was done by megazig.

I have not checked vWii compatbility, though. Maybe someone else can do that for me?

Sorry for the necrobump, btw.

 

[Cyan]

thanks.
I guess it's now v1.5.0? (doesn't really matter, but just for consistencies between all projects)

1.5:
* add ISFS_SetAttr() patches. (by megazig)
	Forces the ISFS_SetAttr() function to continue instead of
	returning -102 when you're trying to change the UID/GID of a file.

1.4:
* fix value for hash_old (spotted by DarkMatterCore)

[DarkMatterCore]

Yeah, I think so. Right now I'm trying to find a way to correct the -115 (ENOTEMPTY) error that appears sometimes when calling ISFS_SetAttr() after applying this new patch. megazig doesn't have his IDBs anymore, though, and I don't have IDA Pro.

 

[JoostinOnline]

The license should also be changed from GPL to MIT, and a typedef needs to be added for s32

Here is a zip file of an updated version of libruntimeiospatch. It's DarkMatterCore's changes and a few of my own that I've made over the past months (nothing special). The only thing that needs to be changed is the license, but I can't legally change that so I'll leave it to Excelsiior.

[Excelsiior]

Officially released v1.5.1 now, updated first post. Thanks to megazig, DarkMatterCore and JoostinOnline.

About the License: GPL is correct, as the original code was bundled with FTPii, which is gpl'ed.

New BSD according to Wiibrew

Then -lrip was licensed differently, it's GPL, as you can see here:

Thanks to @DarkMatterCore there's now version 1.5.2 available.

1.5.2:
* added SSL module patches made by FIX94 to fix some certificate
  errors that occur when attempting to connect to a host using a
  secure connection (DarkMatterCore)

/on a side note: there's something wrong with the vWii-builds of the HomebrewFilter. So expect a minor update of it "soon".

 

[Cyan]

hooo, I planed to do it but you beat me
do you know if it works only with IOS58 or with cIOS too?
I'll try.

Thanks.
