After watching the rise of the Wii Homebrew scene, I can tell you without a doubt that CIOSCORP is the most dangerous thing that has come to the Wii. That's not to say that it isn't a fantastic breakthrough, but this is the type of project that needed to be created over a private chat. In an IRC or private message board. Kids don't read warnings. They see the newest thing, and they go for it. They don't think about the consequences and they sure as hell don't think about stuff like breaking their friends Wii. They get the newest hack and they install it because they want to prove something, or think it's impressive to people that they can install a program made by someone else. These are not people you know. These are not people you can necessarily trust. We all hope that people would be honest, but I have seen far too many liars in this scene to feel safe going by what someone else has said. Don't be a hermit, try new things, that's fine. But don't trust for a second that anyone can or will help you. So if you don't have the means to help yourself in the situation that something goes wrong, then maybe you should step back and think whether or not what you have is good enough. If you can install a channel that runs backup games just fine, then why on earth would you want to install something that has so many risks, that you know almost nothing about, for no gain other than you don't have to click start on a channel? This is a development project, for people who wish to use this project, and it's idea's to make the Wii better for people like you.

As IronMask said, I have the means to replace a broken Wii. I have a spare, I know what to do in the event of a brick. But do you? Can you afford another $250 Wii? Can you fix the one you have if you break it. Don't be too foolish, there's some things that even Starfall can't save you from, and when that time come's the only person to blame will be your self.

I agree but for a different reason.

One of the measures of a good "hack" is the size of the footprints you leave behind. The best hacks provide great functionality while making as few changes to the native system as possible (like getting admin priveleges on a system without being detectable by the "real" admins).

With CIOSCorp you are fundamentally and extensively altering the native system. As I pointed out before you are using a single .APP file to replace at least four different shared .APP files in the IOS titles. There is most likely a reason that those four shared .APP files are different. And that's just for the IOS titles 28 and higher. For the IOS tiles from 9-22 you are completely replacing the IOS title with a single instance of a patched (higher version) IOS title. Add to that the fact that nearly every IOS title on your system is now fakesigned and at least one of the .APP files in each IOS has a different hash than the original.

No one really knows what effect this will have on the system in the future. I admit that it's very possible that this will have no adverse effects at all, but no one really knows.

This is not something I would choose to install. I think the idea was very cool and I totally understand hardcore "tinkerers" messing around with it, but I shudder at the thought of widespread installation of this hack.

Couldn't have said it better, this is the reason why we are skeptical of CIOSCORP, this is the alternative to that.

Now do you see what I'm getting at? CIOSCORP is great, but you never know what could happen later.
 
I'd like it a lot, and be very thankful, if someone explained to me:

1) How originals run at 6x in this and CIOSCORP

2) How they know this to be true

I would like to know, feel free to pm me with the explanation.
 
if the quantum of solace sound issues were because of 3x speed then cioscorp dosent fix this because it still stutters

I'm not sure how they implemented originals to run at 6x with these loaders, but you could test it by comparing with a stopwatch.
I'm guessing it has to do the the CIOS provided by Waninkoko or Wiigator.

Try it with this and see if it's still a problem.
 
3x versus 6x is controlled by the drive firmware, not the ios. The Cios put the commands in for normal dvd access that nintendo pulled to avoid the licensing fees, which is limited by the firmware to 3x speed. The firmware detects the type of disc be it wii disc or dvd disc and sets the drive speed accordingly. Until we come up with a firmware hack or far better caching methods, the games with sound issues will remain. (although my QOS backup doesn't have the sound issues after using cioscorp and burning a copy at 16x quality at 95%)
And i'll quote myself from the other thread about the cioscorp dangers.

Widespread installation of this hack is inevitable. The benefits, once a legal installer/uninstaller is released, far outweigh the risks, which honestly at this point only really exist if you are A.dumb enough to upgrade to 3.5 once it comes out before any testing is done B. you manually remove IOS's instead of overwrite them or C. You get an error installing the System menu wad and are dumb enough to exit wad manager without fixing the issue. The biggest benefit to this method is not the disc channel loading, although i admit it is nice, it is the fact that since doing this we can now play 100% of backup games without errors. All the problems the loaders had (random DRE's games freezing on load, HOD 2+3 etc not working, 002 errors) are eliminated when you patch your IOS. I have tested over 50 original games, and over 100 backups without a single problem. Games that never ran right before or randomly crashed, now work flawlessly. As for making as few changes as possible... All console hacks have always required what i would consider extensive and fundamental modification to the system, be it changing the firmware, IOS, or code in the actual system menu. I still as always advise against those new to the modding scene doing this, however for those who have become experienced installing wads and the like this is really an easy change to make, and just as easy to undo, with or without an installer. Like all progress and change risk is involved, and like anything else its up to you to ensure you have enough knowledge about the subject to minimize the risks before proceeding.

so youre saying, even using the same IOS to run, the commands arent forced one way or another, its all determined at-drive, and the cIOS simply "adds" (enables really, but it fits better) the other mode....okay so you've told me why, now tell me how you know this is the case instead of "cIOS forces 3x on all discs"....cause I've heard both.
 
Three ways i know. One its been said by several of the hard core coders (wii wan etc) two i have timed originals versus backups through the disc channel. the smallest difference was 2 seconds load time (i believe on boom blox), the largest (i believe it was on Day of crisis) was 25 seconds. Three, The wii discs don't identify as DVD, and there isnt any code that is added to the CIOS for actual wii discs, so it has to be using the original N code, which reads at up to 6x, as the dvd code is not compatible with the read commands used on native discs. This is also part of the problem stopping gamecube backups from being played, they are using another different set of read commands for another disc format.

I fixed a bug

[Replace healthwarning with backmenu] ok

I'm working on region free

slowly

channel fix bug


rename pal.dol or ntsc.dol //sysmenu.dol ok

aquilino

Great to see the fix,

I will update the first post soon

So if I've installed the first menupatcher. Do I just rename this on and install over it.

So if I've installed the first menupatcher this morning. Now I see you have a fix. Do I just rename this one and install over it.
Sry for the DP

You can go ahead and delete the old channel, and just install this new channel and thats all,
if you want you can rename the ntsc.dol to sysmenu.dol
 
am i right in thinking that softchip has a setting where you can let the disk choose the language of the boot? if so can this not be implimented into a hack? or am i way off target here
 
Nah, CIOSCORP is better than that!

But cSM is BETTER than CIOSCORP... well, we must wait for cSM but i recommend CIOSCORP when we wait!

Any chance you could inject this into a smaller channel - like the menupatcher-lite channel (its only about 260kb) with no banners/sounds??
5.2mb is HUGE for something you never look at
wink.gif

ok

I do not have images for baner


black screen default

yeah, black screen and no sound - that should cut the size right down
thank you for your time & effort
smile.gif
update channel black screen and no sound

356 kb

ok fishears

channel black screen
 
sorry if i doubled posted the other one never showed up. if i have starfall already installed will this remove it? also will Gameqube backup work with this? has anyone tried? keep up the great work?
 
itd have to be a BC exploit too, they think that is what triggers GC mode, MIOS is likely just what sandboxes it.

PS: I'd like to make sure I have the latest cIOSCorp files, I know there were at least two versions mentioned, someone who knows they have the most up-2-date, please pm me. thanks.
 
No one reads anymore... as Wiigator said the MIOS is fully hacked, the only thing holding gamecube loading back is that gamecube disks use an entirely different disc access mode than wii or dvd. Our current method of loading backups fails with this, so until someone writes a new disc access method that is compatible with GC backups we won't have this feature without a mod chip
