What's new
I have a undamned usb decoder plus board with a yellow led status. Does anyone know what part has malfunctioned or how to repair this?
I would consult the docs if you can find them, and also I can say a USB A to A cable was recommended from UD to upgrade the devices if/when needed.
May I know how UD-USB Decoders are different from USB2DB15 and CS Ver. for JAMMA/NEO GEO? It appears to me that both perform the same job, which is to bridge usb controller and JAMMA/supergun.
I already did answer you on Discord but to clarify, i think both products do the same when we are talking about use USB controllers and JAMMA/NEOGEO, but with different features.
My USB decoder worked fine since 2016 and now I have an issue with one direction (down) all other stuff works fine.
I succeeded in updating the firmware but I still have the same problem :(
Can someone help me ?
Soo it seems like UD haven't logged in here for two years now, i guess we won't see firmware upgrade anytime soon. Did anyone ever tried to tinker with it ? TBH i would love to see it compatible with newer device like the 8bitdo NG controller ...
I sent him a message here as well as a direct email, no response for over a week.

I’m hoping I can find a bunch of the UD-USB Terminal style PCB’s. I’m in need about 6 of them!
Does anyone have an extra one of his db15 to neo connectors? The db15 to 3do converter needs those to make clearance.
