That was the golden tip. Thank you. This wonderful oldschool joystick now works with a couple of emulators, except for mame4all. Does anybody have a new tip for this piplay mayflash adventure story? In other words: how/where do I configure/activate a joystick (mayflash) for pimame? Thx

I figured it out (by browsing in de Forum ;-)
To configure the joystick I added some code to the advmame.rc file (in the directory home/pi/.advance/
At the end of this file are the inputs for the functions. I added the joystick-variables:

input_map[p1_up] keyboard[1,scan0] or keyboard[0,8_pad] or keyboard[0,up] or keyboard[1,scan0] or joystick_digital[0,1,1,1]
input_map[p1_down] keyboard[1,scan0] or keyboard[0,2_pad] or keyboard[0,down] or keyboard[1,scan0] or joystick_digital[0,1,1,0]
input_map[p1_right] keyboard[1,scan0] or keyboard[0,6_pad] or keyboard[0,right] or keyboard[1,scan0] or joystick_digital[0,1,0,0]
input_map[p1_left] keyboard[1,scan0] or keyboard[0,4_pad] or keyboard[0,left] or keyboard[1,scan0] or joystick_digital[0,1,0,1]
input_map[p1_button1] keyboard[1,scan0] or keyboard[0,lcontrol] or joystick_button[0,0]
input_map[p1_button2] keyboard[1,scan0] or keyboard[0,lalt] or joystick_button[0,1]
input_map[p1_button3] keyboard[1,scan0] or keyboard[0,space] or joystick_button[0,2]
input_map[p1_button4] keyboard[1,scan0] or keyboard[0,lshift] or joystick_button[0,3]
input_map[p1_button5] keyboard[1,scan0] or keyboard[0,z] or joystick_button[0,4]
input_map[p1_button6] keyboard[1,scan0] or keyboard[0,x] or joystick_button[0,5]
input_map[p1_button7] keyboard[1,scan0] or keyboard[0,c] or joystick_button[0,6]
input_map[p1_button8] keyboard[1,scan0] or keyboard[0,5] or joystick_button[0,7]
