Ye, I forgot u said it works with usbloader. Man, sometimes certain loaders just have better compatibility with games than others. Driver was a good example, only worked w GX. Anyways, pretty much every solution has been thrown at u in this thread. If worse comes to worse, you may just have to keep using usbloader. I will see if I can track down that game from some friends to test it out and will let you know...

OK, I can confirm this game runs just fine on CFG v70 mod 15, GX 3.0, and WiiFlow 4.0.5. (Also, Im running d2x v9 b49) This game was released in 2007, so there really shouldnt be any compatibility issues with any of the latest loaders or d2x cIOS. Did you upgrade WiiFlow? Even if you did I would suggest you completely delete the sd/apps/wiiflow folder and everything from the sd/wiiflow folder except for your covers and images folders. Then download the latest wiiflow from HERE and extract the contents directly to your sd card. After that, run Wiiflow and try to run the game again. If it still black screens a rerip is probably the last option.
