Which region is the game, and which region is your Wii? Did you set the video mode for GC games to disc in NeoGamma? Once you get to the "NeoGamma GC Backup Launcher" screen, the installed MIOS only matters for the patched MIOS option.
What other games did you try?
Do you have an usb gecko? If yes, you could set NeoGamma to the debug plugin and post the debug output. Well this is not important, but if you had an usb gecko, it would be interesting.

Try disabling Reloader. There is no reason to have it.
There's no reason why it would screw anything up for this game. It's good to have it always on, some games require it on occasion where you don't expect it, like Eternal Darkness when you die.
