I just ditched the raspberry PI and coded the romi directly via the Arduino IDE, using the romi arduino library. Just follow the instructions given in the manual. Once you have everything set up (the drivers, the Arduino IDE, and the library), you can just plug your computer in via USB directly to the micro USB port on the romi control board and upload the code to the romi on the IDE. Then it will automatically run once you turn on the romi.
