I have made a completely homebrew connector strip that fits the VB and works with a pcb game fixed, with help from Kev Mellott, he found the inserts and kindly provided me with a connector I could take apart and measure.
Pics enclosed of the strip, fitted into a VB joined to a game.
The body is a 3D print with 60x inserts pressed in, it fits in a cart case and fits in the VB and I just slotted another game connector and pcb into it to check it would fire up and it did, all works. Couldn’t take a picture showing the game playing and the connector in place due to view angle thru the red lens, but it worked fine.
The problem is the metal inserts, these work out expensive for 60x per strip and means the strip I have made cost at least $20 for the parts alone. What is needed is to find a source for ‘off the shelf’ metal inserts that will accept a 0.4mm pin, be small enough to fit the connector pitch (2mm X 1.5mm) and have a solder tail end that can stick out the back of the connector, so need to be around 15mm total length. The type I have are round and I guess have been micro machined, could do with some sort of press formed type strip of inserts that only cost a few pennies each.
I have searched a lot, if anyone cares to take this up you may have more success, anything found please either pm me or post a site ref and pics here and I can check if I can make it fit a connector.
