Its a ps2 controller (x2) into usb port adaptor. The disc that came with it seems to just be the regular windows xp controller calibration setup. And the controller works fine there. everything works... But when i start epsxe (or mame) and try to map the controls it acts like the left hat switch (dpad left) is being held down. Windows calibrator says ok everything balanced. Emulators say dpad left wont let go.
