# incorrect vertex formats - e.g. if you specify your position format as 3 f32 values and then when you draw, you mistakenly send only 2 f32 values, the Wii will likely hang.+# incorrect vertex count - e.g. if you specify you're sending 4 vertices and only send 3, the Wii will likely hang.+

−If you find your code hanging as soon as you begin drawing with GX_Begin(), here are a couple of possible causes:
+If your GX application hangs as soon as you begin drawing with GX_Begin(), here are a few possible causes:
−* incorrect vertex formats - the vertex format specified with GX_SetVtxAttrFmt() must match what your app sends between GX_Begin() and GX_End()
−* incorrect vertex count - the vertex count specified by GX_Begin() must match the vertex count your app sends between GX_Begin() and GX_End()
+*incorrect vertex data order - vertex data is order dependent - the order GX expects vertex data is: position, normal, color, bi-normals, and texture coordinates
