Great app I've had the same problem others have had where it crashes when you put the bios in the folder  here's what to do  create a folder on your phone root folder called """"""""""""""""dc"""""""""""""""" then in that folder create another folder call it """"""""""""""""data"""""""""""""""" in this folder put your bios in there  once done you can test it by running the bios. You will know it works once you see the system logo starts up. You can put the rom folder anywhere but for some strange reason bios only works from the root or main phone storage. Hope this helps.""
