it seems some people like me, have a TA-079 board, and when using the PSP-290 GPS find that GPS state is always off. the fix for me was that i needed to make a new folder in the memory stick root called "camprx" and put copy's of my prx files into it. i only found this out when i tried to use the original PSP-290 test from deniska, and the instructions told me to make that folder and put the prx files into it
