PAL "Jumper: Griffins Story" on NTSC-U

[CharlieFarly]

Hello,

I've got a NTSC-U WII which has an Argon (Clone) Mod-Chip installed.    I'm also (stupidly) running with the latest 3.3U firmware.

My kids have got the PAL version of "Jumper: Griffins Story".  This doesn't natively work on the Wii - the disc is recognised, but the Wii locks up with a Black screen on launch.   I discovered that the game could be launched using Datel's Freeloader however.

Now that the Wii is running with the latest 3.3U firmware however the Datel Freeloader disc no longer functions (as expected).   I've been looking this afternoon at using GeckoOS to launch the game instead.

If I just select "Launch Game" from within Gecko the screen changes to "Launching Game", but the game doesn't start.  I've tried playing with the "Force NTSC/PAL50/PAL60" options with no luck.

Just wondering if anyone can make a suggestion on the required configuration please?.

Thanks

Charlie
