Hacking cIOSX rev21: controller lag [FIXED!]

[Yuan]

Wow! thanks davebaol, I'll test it now!
Do you remember of another problematic game you don't own that could be used to test it?

Smash Bros Brawl

- Pause loop with rev20/21 EHCI

I will test it soon too.

EDIT: Fixed, cooking mama is lagless too!

Thanks a lot davebaol!

i can't seem to run modmii. i get "application failed to initiate" then i get "can't find base wads"

 

[netspy]

@nando: that's weird, I've never seen such a thing before. Maybe you could try to install ModMii again (in a standard path like C:\ModMii) ?

@davebaol: Thanks a lot ! That's really great !
I added your solution on the 1st page of this topic (I didn't have the time to test it yet, but from what I read it seems to be working fine).
Can you please tell us what the bug was and how you fixed it (i.e. what change you made in the source code) ?

Moreover, can someone get in touch with Waninkoko to tell him about the fix davebaol has found ? It could be useful if Waninkoko ever release another rev in a few months, he could include the fix.

 

[nando]

alright, i need help. do i really need the beta to use the fixed EHCI module? or can i do it with the regular modmii. and we are replacing the EHCI file inside modmii/Modules/W21Modules?


i'm asking because i'm having a hell of a time downloading the beta. the link takes me to the download page but there are 6 unlabeled download buttons and i can't seem to select modmii.


i don't think i'll be able to get this working either way since i keep getting invalid files.

Modmii beta direct link removed by me - job done

 

[nando]

thanks sock99

i'm still confused as to which EHCI file i'm replacing. i got modmii running, and i can make the wads, but modmii tells me i have a bad file.

 

[netspy]

It's normal that ModMii tells you the file is invalid, since it's a modified version and ModMii is not expecting such a resulting file. Don't worry about that.

 

[davebaol]

For building cIOS[]-v21 with fixed lag where is the slot and is the base follow this steps:[*]Download and unzip ModMii4.4.5B-BETA [*]Replace "modules\W21Modules\EHCI.app" with mine. [*]Launch ModMii4.4.5B-BETA[*]Choose download page 4[*]Select the slot and the base you want, for example "2502156 = cIOS249[56]-v21" and/or "2502157 = cIOS250[57]-v21"
NOTE 1: You can also choose base 37 or 38.
NOTE 2: Don't select the one with [EHCI-v19] appended.[*]Enter D to download the wad[*]Ignore the warning message

Checking entries in COPY_TO_SD\Download_Log.md5
COPY_TO_SD\WAD\cIOS[]-v21.wad: Invalid
Results: 1 files processed, 0 good files, 1 bad files.
It's absolutely normal since the EHCI module has been replaced so MD5 check fails.[*]Use MultiMod Manager to install the wad(s)
NOTE: despite the file name it's a real rev21 without lag[*]Enjoy it

CAUTION:
After replacing EHCI.app in modules folder ModMii4.4.5B-BETA will actually generate all rev21-LagFix cios with my EHCI module.
If you want to download official rev21 wads you need to restore the original EHCI.app

I've fixed the wrong message management in timer.c by making a punctual rollback to rev19, just a few lines of code.
All the other sources committed by Wanikoko till 2010-12-25 (last EHCI module included in rev21) are untouched.

Yeah of course, if somebody tell me via pm how to contact Waninkoko I'll be glad to give him the fixed source so he can commit the changes.

 

[BBogey]

daveabol, nice you fixed it!
Could you share the source or diff.

If you like to use the modified elf with other bases, just replace elf in rev21 folder, then build rev21 wads.
See this x4mers post.

Why not just post the changes here, since you're already obligated to by the GPL.

 

[churkus]

If this lag issue is caused by HD spindown, you can take Seagate Expansion 500gb off this list, as it can be set to never spindown via the seagate manager software. if this has already been done, ignore!

 

[netspy]

Thanks Churkus, but I set the spindown delay to 'Never' before testing, and the lag was there.

 

[jesquinas]

I dont know where is the screen where you choose a save file in "Wario Land: Shake It!" .Can you tell me where is it for testing the lag issues in my hard disk?

Thanks.

 

[netspy]

Well, it's not really hard to find.

Load the game, press 2, and you are on the right screen.

Yeah I know. As you can see I've already built and tested base 57 too

• Shaun White Skateboarding works perfectly on base 56 and 57 (previous cIOS249[56]-v21[EHCI-v19] doesn't support that game).

Also you can easily change the slot with ShowMiiWads.

Because right now I'm at work and the source is at home on my pc.
Please be patient, later I'll post the changes here.

In fact the lag issue is spindown independent.

 

[davebaol]

Ok guys, sorry for double posting.

Since I can't post the changes right now and also a few people asked me via pm how I actually fixed the lag issue I'm gonna try to explain you what happened in EHCI module of rev 20 and 21.

Let's start looking at the diff in timer.c between rev19 and rev20 (first time lag issue appeared):
https://github.com/waninkoko/ehci-module/co...922c9837#diff-5

As you can see in rev20 the messages 0x555 and 0x666 have been unified in a single message 0x666.
Also the send/receive sequence has been changed by removing the send_message(0x555) above the cycle and the reveive_message() below the cycle.
And the start time of the timer has been set to 0 instead of 1 million.

Not sure, 'cause the issue is really subtle, but I suspect the timing logic in rev20/21 triggers 2 watchdogs in rapid sequence maybe even overlapped, so generating the tedious lag for certain drives.

If someone else has a better explanation I'll be glad to read it.

That's all for the time being

 

[netspy]

Thanks a lot davebaol ! Thanks to you, I think we've got the best possible cIOS right now.

 

[FIX94]

Thanks davebaol, now everything works perfect, no lags at all! Do you know why waninkokos module is 14,5kb and your compiled version 14,8kb? I compiled the official module and it's also 14,8kb, I don't understand why.

 

[davebaol]

Maybe different platform, devkitPro, compiler settings, or stripios... really don't know, sorry.

Ok,Thanks :-)
