Hacking cIOSX rev21d2x: Yet Another Hot Fix!!!!

[xfcrowman]

Just tested COD3 and it works! If I remember correctly, the IOS reload for this game happen between missions, so I play through 2 missions without issue.

@xfcrowman
That's correct!
Thanks for testing.

@ anybody having a modchip installed on the drive
Please test ios reload block through USB/SD.

d2pro 9 wire modchip (on a wiiclip) installed.

Tested:
Call of Duty 3 (PAL)
NeoGamma R9 b48
running under cIOS249[56]-v21d2x5-alpha1,
with Block IOS reload setting set to : For Discs
Loading from 4GB USB drive, WBFS format

...WORKS. Levels load up fine instead of returning to System Menu.

Also tested exact same game with exact same setup, but with the modchip removed, and same results.

Ok, forget it.

So it has never worked even for Waninkoko's cIOS, right?

@Fox888
Thanks for testing

I found the issue. The cIOS checks if the disc is a DVD5 or DVD9 directly after reading the disc id. But you can only set the audio config directly after reading the disc id, if there something read from drive in between, it fails. (if the cIOS doesn't know if a disc is DVD5 or DVD9, it's going to cause 001 error on one of them)

I have an idea how to fix it:
Don't call __DI_CheckDisc after reading the disc id
Put the code from __DI_CheckDisc into __DI_CheckOffset
Add a variable to the config "typechecked" with default false
Only execute the code from __DI_CheckDisc once and set typechecked to true

The change __DI_CheckDisc does to the config seems to only be required for __DI_CheckDisc, so the above should work and don't interfere with anything else. And it only checks once like it does now, so it doesn't cause a major slowdown, like always executing it would.

PS: Some anti piracy could call reset->read disc id->audio config for "fun" to check if a cIOS is running. At least i could identify if a cIOS is running this way, with the changes i suggested this wouldn't be possible anymore.

@damysteryman
Ok, thanks for confirming.
Initially with my wode I had a terrible slow down accessing the drive (blue led always on) when launching a new game after exiting a ios reloaded game.
Then the issue has disappeared after anticipating usb/sd initialization code in the same place where the dvd drive is initialized by the original DI module.

@WiiPower
Hmmm, it looks reasonable.
However I'd need your modified neogamma to test this mod.
I think you'd better modify waninkoko's dip module by yourself and send me the new source so that I can merge it with mine.

PS: Did you read my pm?

 

[davebaol]

@WiiPower
Just an optimization.
I'm believe there's no need to add the field "typechecked" to the config.
You can merely reuse config.type to check whether the dvd type is already known.
Note that in plugin.h the enum constant DISC_UNKNOWN is already defined but never used in the entire module.

Grr, i can't do it the way i wanted to do it, infinite loop...

It's a bit dirty since i make it fall back to DVD5 while unknown and i don't check the type for disc id or bca reading. But for those it shouldn't be required. If you have a nicer way of solving this, i listen.

This NeoGamma will only print "Audio streaming set" on screen for gamecube games and if it could actually do it. If it can't do it, there's nothing on screen. 001 DL games might be worth checking now, Metroid Prime Triology for example. For me audio streaming + SL 001 games work.

Hi,

CSI - dealy intent : This gives me a Error# 002 with a blue screen after selecting level 1 maybe patched here
CSI - Hard Evidence : seems to worked

 

[davebaol]

@old_darkness
CSI Dealy Intent works perfectly here.
Error 002 on ios reload has been fixed in d2x v4 and nobody has reported any issue until now. Well, nobody else but you.
Also, some users have reported that the other 2 games of the same series are working properly.
And AFAIK there's only 1 type of ios reload, so theoretically all games should be supported the same manner.
TBH I don't know why you get error 002, maybe your game is patched somehow.

@WiiPower
Your test app works for me with MPT, so DL games seem to be recognized properly.
GC games not tested.
Also I have not looked at the source yet but I think I can say you did a great work.
I'll merge it with the upcoming v5 beta1 asap.

Don't rush it, take your time and see if i did some mistake. I don't like it when someone blindly trusts me.

Does patching the game to use another IOS break the 002 error on ios reload fix? If yes, can the code be updated to fix 002 error in that situation as well? If a .iso is patched to use another IOS, the change is only in the tmd. Ok and the tmd is the info which is used to determine which IOS is to be loaded. But the info inside the apploader is the one used for the 002 check.

Can you post the part of the code that relates to the 002 error fix?

 

[davebaol]

You can find the source in d2x v4 final package in the 1st post: ES module -> plugin.c -> lines 182-207 (IOCTL_ES_DIVERIFY).

That code has been added by me only to fix error 002 and to avoid infinite ios reload loops if the wii crashes in the middle of an ios reload (title_id check).

Ok, i found it and i don't see any reason why it would fail for patched .isos. You could determine if the tmd info matches the info from the apploader at this point, but it would lead to the same *(u32 *)0x00003140 = (*((u32 *)0x00003188)) | 0xFFFF; anyways. Maybe the IOS Reload block is disabled in this situation for some reason? Too bad i don't have a 002 IOS reloading game here right now. That would be something i would like to debug with my usb gecko.

 

[davebaol]

And that lines are unchanged in d2x v5alpha1.
The only mod I made to ES in v5alpha1 is a few lines above in IOCTL_ES_LAUNCH to call a new DI ioctl that saves the config state for DI itself.
So nothing to do with 002 error.

davebaol:
The game "Sakura Wars - So long, my Love" (SAKPNS) doesn't work with the d2x cIOS.
When starting the game with NeoGamma or CFG the "An error has occurred, Press the EJECT button, remove the disc, and turn of the power to the console. Please refer to the Wii Operations Manual for details" shows. But when I run the game in CFG with hermes5.1base57cIOS it works.
Maybe this is something to add to the to do list (not high priority though). By the way the game is a DL game but without IOS Reload.
Could someone else also confim the above statement?

Which IOS does the game use when started from disc channel? I hope i don't need to ask, but i'll do it anyways:
Since hermes cIOS with IOS57 as base works, did you try the same base for d2x as well?

Hehe of course I tested that

(with both r21 & d2x v4 with different bases, and d2x v5alpha1base56)
Actually I havn't checked what IOS the game "normaly" uses yet

 

[WiiPower]

Hm, Hermes cIOS are always IOS38 + X? Did you try d2x with IOS38 as base?

 

[IceIceBird]

Yes, didn't work.

 

[davebaol]

Yeah, I can confirm.
However d2x doesn't seem to be responsible for that (maybe).

The PAL version of Sakura Wars works for me with d2x v5 alpha1 (base 56) and GX 2.1 via USB from a FAT partition (I'm assuming gx is actually using its own dip module to manage the fraglist, just like cfg does).

Unfortunately it doesn't work with the same cios and NeoGamma R9 beta48 via SD from a WBFS partition.

PS: Sakura Wars specifies ios 53 in tmd.

And if you try with an WBFS partition in GX ?
