How can I use my SD card as my internal storage in my X2 TV Box?

Saw some people posted about using SD as internal memory, but what about a tv box. recently acquired a Tronfy x2, H3 ,1GB/8GB. My game files will be installed to the external memory instead of the internal storage as small as 8 GB. I tried to use clockworkmod recovery 4.0.3. but it does not work, can anyone give me some advice on how to build the SD card into internal memory?
