Can't exit Sega model 2 with joy to key

[wardiz]

Hi there I've got an upright racing cabinet with a Logitech wheel / 2 aimtrack guns and an ultimarc u-hid for extra arcade buttons .

ive assigned an exit and enter button with joy to key on my Logitech wheel and am able to exit mame and mame games by pressing these .

If I choose the model 2 and play virtua cop or any other shooting or racing game on it I am in able to exit the game by pressing the button assigned to escape . 

I have to press "alt F4" to get out of the game and back into hyperspin .

Would like to know if I can avoid having to use the keyboard to exit .

thanks .
