Im using joytokey for every emulator to have extra commands mapped to my joypad.
Using Joy-To-Key to also control MA seems not possible to me. Because this means to launch joytokey when MA starts, terminate it before certain emu is launched (to be able to start joytokey for this certain emu) and start it again after certain emu + joytokey is terminated.
Also:
I tried another pc with windows7 and fresh MA install, exact same results.
I tried another pc with xp and fresh MA
This leads me to believe MA is not compatible with pc038 usb adapters.
