Don't expect the patches today, and i think they should work on all cIOS on all partition types.

cIOSrev9 is a primitive cIOS compared to the later ones, and it seems the only reason why the later ones don't work, is the check of the module names in the cIOS. The game checks for usb2, sdhc and mload. cIOSrev18 started using the name usb2, rev10 was the 1st with sdhc support and i think rev18 was the 1st with mload support. These checks are also the reason why Hermes cIOS don't work, because they all use these names.

I don't really feel like sifting through this thread. Does the game only check for cIOS in slots 222, 223, 224, 249, and 250?

panmusic · May 19, 2010

Very nice explanation WiiPower!Thanks!
I certainly hope somebody releases the patches as soon as possible because the wait is killing me...

Satangel · May 19, 2010

Thanks for the explanation, should help a lot of members!
Saves us loads of topics, thanks!

Well are you sure? I browsed through the dol and can't find any occurrences of those strings (usb2, sdhc, mload and so on)... Is it obfuscated?
Also no symbols with names Waninkoko or Hermes found in the main.dol of the game unlike previously linked pastie

EDIT: Disregard my post, it was nonsense

I was told the strings are encrypted in the .dol:

Hmm, rather than encryption this seems much more like bit shifting and stuff, since all occurences of each character repeats in the obfuscated one... I believe direct patching of this data doesn't work hence no one released yet...

ps: they only differ by 7 in their ascii equivalents...

edit: if checksumming of this data is also lame like the obfuscation then one can just swap the order of the bytes

I'l just give it a go swapping the end of strings..

If I installed the OP's original WAD of cIOS rev9 on a LU64+ unit, did I just screw something up in the Wii's filesystem?

I uninstalled the WAD so I guess it removed whatever the original WAD installed but not sure cause it seems a lot quicker to uninstall than install.

Uninstalling WADs is really fast (few seconds)

Don't uninstall system related wads unless you know what you are doing. That's something that can easily brick your Wii!

cIOSrev9 just won't work on new Wiis, you can install it and try to use it without any danger. It may just a little problem getting a new cIOS again, but nothing to worry about.

ocdetective · May 19, 2010

OK here is an update to what I found running on 3.2U with original rev9 installed to 249 (no updates).
GX with not run on rev 874 any setting for 002 fix but will run on rev 782 with 002 fix to On (possibly anti will work too but untested)
Cfg will not run on either 56 or 57a but will run on 44 with anti 002 setting to On. About to test 45 to see if that works.
OK tested rev 45 - confirmed NOT working on original rev9. That would indicate that the patch installed between 44 and 45 on Cfg and 782 and 784 on GX does indeed have some effect (the fix for games which need a disc in the drive to play (like MP3 and De Blob))

What do you mean by not being able to install a new cIOS again though? Am I stuck with cIOS rev17 on 249 from now on?

I still have cIOs rev17 on my Wii on 249 which still works. The uninstalled WAD did not brick the system luckily.

Also, can we freely upgrade and downgrade between cIOS's right? Since you said I may not be able to upgrade, I'm thinking of upgrading to rev19 and back down to rev17 just to see if there is a problem.

WiiPower · May 19, 2010

I thought that was installs the cIOS as IOS249. In that case you wouldn't been able to use IOS249 to update your cIOS, that's all i meant.

Sry for asking, but if the module names making these problems, why doesn't someone just rename them?

Oh ok. From what I know the OP's WAD had patched cIOS rev9 to ISO223. I checked and it still says I have cIOS rev17 on my Wii on 249 which is still working. So I guess I cant use IOS223 anymore from what I understand, but I guess I have no immediate need for it anyhow as I have Hermes 222 v4 on 222.

Dr. Clipper · May 19, 2010

Yeah, don't wait on the patches. Play the game from those discs I'm sure all of you have...

As for timing of the patch, I'll be trying to make one of my own in about 17 hours or so. Somebody will probably beat me to it now that the cat's out of the bag.

WiiCrazy, you're close, but there are some strings on a 13 character shift too.

Thanks for testing that. It clears up a big problem we were having. I guess XFlak wasn't testing things properly. XFlak, any word on this?

QUOTE(BOTCK @ May 20 2010, 12:31 AM) Sry for asking, but if the module names making these problems, why doesn't someone just rename them?

Because we're not Waninkok and Hermes.

I tested it on 57b and it worked fine

I was using cIOS249rev9 installed to slot 250, with anti-002 on

edit: I am 100% positive it loaded fine from both cfg rev44 and rev57b, before I launched the game I went to the global options and saw the rev #. However, I used the same "USB-Loader" Supporting Folder during both attempts (I think it was a recent USB-Loader folder and not the one from rev44, but I cant remember for sure).

edit2: when i get home (7 hours from now) I will re-test to confirm it still behaves the same way

And you played it long enough to make sure it didn't crash part way through the game?

If so, then things are very weird and there is something different between your Wii/launch method and ocdetective's.

XFlak · May 19, 2010

it was late, so I just made sure I got it to load to the game's main menu

if it were to crash... wouldn't it crash right away (even before the health warnings splash screens)?

edit: I will perform any tests that people request when I get home, but it seems as if it may be pointless because a patch will likely be released soon thereafter
