Hacking WIT (Wiimms ISO Tools) GameCube disc support

[Nisto]

Oh, I see. I hate to be annoying, but what is a good method of composing data from a GC disc to a Wii format that will play on Dolphin then?

 

[tmv_josue]

I don't think so. Should even be a bad thing.

...wat?

 

[Nisto]

Well, from what I can tell, some people did do it? I read in a post here somewhere that they needed to get a Gamecube game running on their Wii with (s)neek, so it had to be a Wii image, especially since wit apparently only does produce Wii images, right... ? So I'm wondering how I can do the same -- except, I don't need it to run with (s)neek, but on the Dolphin emulator.

If I remember correctly, I did try the default format (WBFS), but that wouldn't run..

 

[Fishaman P]

Well, instead of running it with SNEEK, I'd imagine they just loaded DIOS MIOS or what have you.
Anyway, if you want to play GC games in Dolphin, just compose a GC image then.
I don't remember exactly, but a bunch of Melee SD Remix threads had tools to unpack and rebuild GC ISOs. They were all confusing and buggy, but at least they worked.

I think some of the names were generic, like GC ISO Tool or something.

 

[tmv_josue]

I think DMTool can do that job in an easy way.

 

[Nisto]

Ah okay. I was just hoping to be able to do everything through wit. But turns out it doesn't properly extract some GC files to begin with anyway (e.g. fst.bin from Resident Evil 0). And I know it may still only have experimental support for GC images, so... Guess I'll stick to GCReEx. Thanks anyway.

@Wiimm, Ive been banging my head against the desk for several hours now because I just couldn't manage to get wit to work on ANY of my GC isos (I even manually verified hashes against redump and they were all clean).

Then, in a last ditch effort, I downloaded wit v3.01a and everything works as expected.
So, I'm posting just to let you know that there might be something wrong with the Linux x86_64 binaries of v3.02a, or I'm just dense but I'm at my wits end what else it could be.

Here's the output I'm getting with v3.02a, on any wit command, on any GC iso I've tried, running the Linux x86_64 binaries from your website:
Both v3.01a and v3.00a work fine on all ISOs that don't work with v3.02a (at least all those that I've tried so far). Tested with wit copy, wit isosize, wit verify and a few other commands.

Do you get an assertion like:

!! wit: ERROR #126 [FATAL ERROR] in wd_read_part() @ src/libwbfs/wiidisc.c#865
!!      ASSERTION FAILED !!!

After some changes and fixes for GC games I didn't removed this assertion.

 

[gayrightsfalcon]

Yes, I got this error with download/wit-v3.02a-r7679-x86_64.tar.gz
you may want to reupload a fixed version.

[lol@lolilou bin]$ ./wit DUMP ~/dev/fpga/Resident\ Evil\ \(Europe\)\ \(En\,Fr\,De\,Es\,It\)\ \(Disc\ 1\).iso

Hi I've been using WIT for a long time along with WITGUI. recently I updated to Catalina... oh boy..... anyway I've some new GC iso's I would like to add to my HDD but for some reason I can't open my games folder anymore. I get the same ERROR #126.

I've tried manually installing WIT version 3.01 but still the same error.

edit, I had to use
>export LC_ALL=en_US.UTF-8
>sudo spctl --master-disable

now version 3.01 is working ok from the command line.

edit 2:
if WIT 3.01 is working but WITGUI isn't:

Remove WITGUI and the settings from "application support"
Installed WIT 3.01 from the command line
then reinstalled WITGUI.

All is working with version 3.01 cheers!

I haven't been online at GBAtemp for months. Are there any open questions for me here?

Hi Wiimm,

Thanks for asking if you have time to spare a version 3.02 that won't give error #126 would be nice but if the only difference is "--progress", then I could happily live with with 3.01. Thanks for making these awesome tools. cheers.

Hi, is there any chance you could please consider updating WIT to not only fix the error #126 issue with GC discs introduced in 3.02 as mentioned above, but also to fix the bug that destroys apploader.img in Star Wars: Rogue Leader?

hey all, new to softmod, please redirect me if this has been answered already.
I am on Mac OS, Using witgui, and have had no problems transferring my WBFS onto my drive.
However, witgui cannot detect the gamecube ISO i have in my folder.
Check terminal output below:

cd /Users/me/Downloads/wii/ISO/Legacy

~/Library/Application\ Support/Witgui/wit list --recurse . --sections

!! wit: ERROR #126 [FATAL ERROR] in wd_read_part() @ src/libwbfs/wiidisc.c#865

!! ASSERTION FAILED !!!​

WBFS manager is not detecting my drive, and Wii Backup Manager opened through wine was unresponsive, so for now just gonna troubleshoot with WITGUI.
