yeh i got three cabs in a row
2 work fine with the rassberryjamma
and one has no controll’s
i think it is a bad ground issue
i think my cab that isn’t working on on the rassberryjamma ( but will work in
mvs etc is bad ground and i think
it is the cabs jamma female contacts may be used to a fatter pcb..
pins inside cabs female connecter need a little prying to get good connectivity with the jamma edge on the rassberryjamma ground contacts
will update
Setup button?

Re: Setup button?
sega jamma has on the jamma
loom female cab side ground pins for both sides top side & parts side
in my egrets only has top side ground pins
i believe this is the issue as both my egrets are not playing on the rassberryjamma
on jamma female cab side F & B
underside ground pins are not occupied by ground wires. i think this is the issue
causing the rassberryjamma to loose
connectivity with the arcade stick and buttons. ?

Fixed
i found this issue is a low voltage issue
cab side
get yourself a voltage meter jamma adaptor so you can monitor your
5 & 12volts
i found 5.15 & 12.3 is a happy level
once voltage is at this level all controll’s worked perfectly
