Thanks again for your clear explanation. Sorry to bother you with this Amiga Gamebase and thanks for your patience.
I will try your settings and revert.
One question concerning the inputs: Which are the settings read by gamebase? The one set in the "inputs" in WinUAE or the one set into the script? I am still trying to set up the joystick as per my control panel mapping.
I would like to set the joystick with the following keys :
button 1="I"
button 2="W"
Up : R
Left : D
Right : G
Down : F
But I am afraid I did not catch up really how to do that or if settings have to be made into the script file

PS : mouse is set to Joy1 and working good
