Ok, I've browsed for hours, and can't find a single solution.

I have just recently downloaded NeoGamma R8 b7 (and have tried some more recent versions too), and no matter how I open it in HBC, the instant I select it, the screen just goes black. I have never gotten it to run before, and I have IOS70 installed. Al I want it for is to run NSMBW off my modchip, which has been able to run all games except this one (and yes, I know why). Can someone please help me?
