requirements. The requirements are that they can be stretched to odd sizes, open the program and the rom file with one line of code and that support windows joysticks. Very few emulator programs actually fit these requirements. Your problem that your having with the GPS is that it is not embedding into the program. this can be caused by touch screen monitoring programs, web camera monitoring programs, antivirus programs and several others. Have you installed any software recently that has something running in the background? Eliminate any unnecessary processes that are running in the background and this should resolve your problem. Good luck with it.
