Rygar NTSC on PAL Wii

[Taz]

Hi,

I'm dying to play Rygar, as it was one of my favorites on the 8-bit NES.
I had no trouble with playing a patched Metroid NTSC to PAL with my chipped Wii,
but the later NTSC games that were patched to PAL only gave me black screens.
I never used a region-app until now, since I could just boot them off the chip
using the regular disc-channel.
I tried to patch it to PAL and do the same: black screen.
Loading the (patched) game using GeckoOS I get a scrambled screen with some green bars,
and the Wii freezes. No Wiimote response.
Should I boot a non-patched game in GeckoOS?
Also: how can I access the GeckoOS config? I only get the "Insert Wii game and reset"-screen
