Hacking Mario party 8 and 9 black screen on USB Loader

[Deleted member 794115]

Hi folks,

Whenever I try to play Mario Party 8 or 9, black screen and I need to reboot.
I have an european WiiU, PAL games from VL Vault LEGALLY downloaded, and set on my FAT32 partitioned HDD with TinyWiiBackup.

I managed to get ~every game (did not tested them all) working by switching cIOS to 251 in GX Loader, but those 2 are giving me nightmares.

I'm on a "fresh install", following every single step of the wiiu.hack.

I've spend the day trying to resolve this issue, spending my day reinstalling cIOS or changing settings in GX Loader.

If I can do anything, please tell me. I'll post a syscheck tomorow !

Thanks in advance <3

NVM, i found my solution:

• completly reset my GX Loader settings to default
• Video mode : Disc default
• deflicker off (safe)
• framebuffer
• language french
• IOS to default

That worked for almost every game, but for Mario Party 8 specifically, IOS to 250
