Hi there.
I have got a Neogeo 4 slots , I've installed Unibios 3.3 free version and I plugged it.
So I got these issues:
Slot 1 ( Works but lines on screen ):
Others three slots don't work.
If I enter in test menu I get just one slot , other three, it doesn't show up.
Any ideas?
Maybe faulty board or some connectors oxidation??

I've already clean them but unfortunately it didn't work.
Should I use some special cleaner??

Measure your 5 volts on the jamma connector on the 4 slot, you probably need to turn up your voltage a bit.

I would also double up the cables from your power supply (Gnd and +5 volts) to the Jamma connector, it’s hard to see if there is one or more but one small cable will struggle to supply the current you need.
Good luck.
