Hacking Question about PAL GC backups on NTSC Wiis

[Omnigamer]

Hello, I'm mostly new to this branch of modding, so bear with me a bit on this.

I recently installed a WiiFree 2.45 on my NTSC-U Wii, and I'm trying to play a PAL gamecube backup with the system. To the best of my knowledge, everything is soldered properly and working on the hardware end. When the system tries to boot the PAL game, however, only the sound plays through, and the video cuts out. I'm thinking this is some limitation due to the 50 Hz nature of PAL video, but I know it can be done, I just haven't gone through the proper steps. I tried loading it through GCOS as well, but the signal either stops completely or is again limited to the sound in all of the loading options. Is there some pre-patching I need to apply to the disc so that the video can play on standard NTSC television?

I know this question is probably better asked elsewhere, but WiiFree's forum is currently down, so I figured you guys would be just as likely to know how to help.

Any ideas?

Edit: On further research, I've discovered a workaround and can now play happily. Thanks anyway.
