Help with Wii Party on USB Loader GX

[Abaw245]

Hello, new member here. I thought this would be the best place to ask for help regarding an issue that's been bothering me for a long time and I never managed to fix it.

Here's the problem: All my games work except for Wii Party, when i try launching it the Wii just goes back to the Wii Menu.
Here's what i tried so far:
-Changing video modes (NTSC,PAL50/60,Region Patch);
-Setting a different IOS (248,249,250,251);
-Updating to the latest version of USB Loader GX;
-Trying both a USB Flash Drive and an external HDD (tried both formatted to FAT32 and NTFS);

I even tried to ask for a friend to try on her own Wii with the same dump as mine and she actually got it working but she doesn't know how she did it and she doesn't use her Wii anyone so I doubt asking her again would help.
This leads me to believe it's an issue with my own Wii but at this point I don't know what to try without risking bricking my Wii by messing with cIOS.
I currently don't have a Wii party copy with me to do another dump and I can't really ask my friend for hers assuming she still has it and i really want to avoid having to buy another copy of the game, so if anyone can share any advice to help me it would be greatly appreciated.

Thank you in advance.
P.S: I noticed on a lot of posts regarding this topic that sharing a system report can help figure out the problem, so I'll just save the trouble and provide mine on this post (hopefully I format this text correctly, sorry in advance).

It's been a long time since I've been in this forum, but your SysCheck looks fine.
Also, kudos for actually trying every possible fux before posting, hope more Wii users whete this considerate.

So, if we rule out every possible problem with hardware (unless... you haven't tried FAT32 with MBR partition instead of GPT... use Rufus to format your drives/usb to MBR!) then the probable cause is the loader itself.

I'm talking from experience here, USB Loader GX has given me a lot of problems before, and just like you, I've checked cIOS, partitions, different ISOS/WBFS files and the problem is persistent.

Try CFG USB Loader instead, and check if that one actually loads your game! Don't worry about the settings in CFG, I've been using it since 2010 and has NEVER given me any kind of problems.

Hello, I tried your loader and I have both good and bad news:

The good news is it actually worked!
The bad news is that after the loading screen the game just hangs on a black screen before showing the title screen.

Also I know this is nitpicky but I would prefer if possible to get this game working on USB loader GX as it's my preferred loader and I already have proof that it can work with my friend's Wii.

I actually have had that particular game working in both GX and CFG for years.

Then I'd guess it's a problem wity either your USB/THUMBSTICK/HDD/Wathever rather than software fault.

Try the following: Grab a different USB device and format it with RUFUS into a FAT32, 32kb Cluster Size and MBR boot partition instead of GPT and recheck if that fixes your issue!

If not... then I don't know what might be causing this.

Edit! Now that I thought about it... if |MBR|FAT32|32kb cluster| fails, then I'd roll back in GX/CFH versions until I land on one that loads everything correctly.

I'm very happy to inform you that I managed to find the fix!

Turns out it wasn't a problem related to neither the loader, the drive or the Wii itself. All of this happened because I was running USB loader GX through the external drive instead of the SD card. I simply changed the target drive in the homebrew channel to the SD card and loaded the loader from there and it worked with the default settings.

I cannot believe that something so stupid took me such a long time to finally figure out

Thank you for the Rufus suggestion by the way, having the USB formatted I didn't feel like copying USB loader GX on it again so I just used the SD card and that's how I found out.

Thank you for your help!

I can finally let my friend know we can play this game again all together next time we get to see each other at a party

Damn, totally slipped my mind that possibility.
Hm... yeah, glad it's fixed.

Use ModMii's Syscheck Updater. Your cIOS is quite outdated.

Yeah I thought I could also do that as I don't think I've ever updated any of my cIOS since like 2019 (it's already been 6 years), thank you for the suggestion.
