Do you know where i can get the little japanise artwork for the start buttons?
Could you also tell me what button and joystick i have to buy to restore the CP?
Are they seimitsu or sanwa?
For one panel you need this :
2 x BUTTON SEIMITSU PS-14-G black / blue
2 x BUTTON SEIMITSU PS-14-G black / green
2 x BUTTON SEIMITSU PS-14-G black / yellow
2 x BUTTON SEIMITSU PS-14-G black / red
1 x BUTTON SEIMITSU PS-14-D black / blue
1 x BUTTON SEIMITSU PS-14-D black / yellow
1 x BUTTON SEIMITSU PS-14-D black / red
2 x JOYSTICK SEIMITSU LS-32 (with red balltop diameter 35mm (ref seimitsu LB-35))
I can scan my start artwork if necessary.
and finaly add japanese controls to obtain that 
Wrong button for the start and select and wrong color for the balltop of the second player
