How To Train Your Dragon: Black Screen

I downloaded How To Train Your Dragon today, and well, when ever I go to the options menu or the blacksmithing part, the screeen turns black... Any help would be appreciated

What flashcart/emulator are you using, also what firmware are you using?

I am using a R4SDHC clone, with the latest kernel.

Either put wood or ysmenu on your r4 here is a link to each: http://forum.romulation.net/index.php?topic=36273.0 -ysmenu(for clones)
