Short answer is that OD is the one you need.
Darthcloud has OD (Open Drain) and PP (Push Pull) for Neo Geo and the 2600/SMS versions.
Typical parallel input system simply use a switch between input line and GND which pull it low on button press. The input line idle high via a pull-up resistor in the console. To best emulate this behavior use the open drain schematic.
I made both to provide a complete collection of cables. I have the OD version for my Neo Geo and it works great. I'm working on a internal version also.
Thanks a lot for the explanation, I will get the OD version sent off for manufacture, look forward to the internal.
Again thanks
Maybe a daft question but what does
OD & PP stand for, looking at the neogeo , supergun, jamma adapter
Thanks
