no custom ikbd, I see that once the menu is displayed, the game stops 
reading fffc00 to check if some byte were received from the ikbd.
At the same time, the dsp is running during the menu, but there's no 
music ; I wonder if the problem is not that we have a loop where the cpu 
works with the dsp, but never finish in time, so the cpu will never 
reach the part where it should test for key/mouse/joystick.

At this point, I would say it could be related to some instructions' 
cycle accuracy, bu I'm not sure. Can't be fixed at the moment anyway.
