Maybe your just not meant to play out of region games..... If forcing the video doesn't work, try using a different loader. That could be your problem.
Come to the Irc room to get help or just have fun
Motivation alone is not enough. If you have an idiot and you motivate him, now you have a motivated idiot.
Many PAL games could work on USB Loader GX by forcing NTSC on video options. I managed to make Mario Party 8 (PAL) work by using AutoPatch video option. Link's Crossbow Training (PAL), WarioWare - Smooth Moves (PAL) and Wii Fit (PAL) are the ones I'm having problems with. These 3 titles only work with SYSTEM DEFAULT video option but the screen flickers and it's in black & white (PAL refresh rates don't work with NTSC TV's like in North America / Canada)
