Altirra help?

[legolas119]

hi all,

i post in this old post my question about key mapping for Altirra. 

Unfortunately my Logitech rumblepad 2 hasn't the START button mapped on Altirra and I can't add it in the Input mapping section on the emulator settings.  So i would like to add START (F2) and SELECT and OPTIONS using the LB hotkey. I tried to map the button in this way:

but it doesn't work, I have to push F button on the keyboard.  Can you suggest how I can modify this script?

 

thank you!
