Hardcoded toggled inputs (eg. simulated hi-lo gearshift-lock in racing games) can now be manually turned off or on by the user. [hap]

Browse Source 
For example, to disable the toggle on the shifter in outrun, open /cfg/outrun.cfg and add toggle="no" to the port tag, like so:
<port tag=":SERVICE" type="P1_BUTTON1" mask="16" defvalue="0" toggle="no">
