Hello all,
I'm looking to assemble my first little arcade controller to use in tandem with my Supergun, which takes a Neo Geo/DB15 input for controllers. This is my first time working with it, so this may be a bit of a dumb question, but I'm not sure I fully get daisy chaining.
I'm wiring directly to a DB15 breakout board, and have been told it's easiest to daisy chain my ground wire between each input (6 buttons, coin, start, 4-way stick). The hot wire from each input going to the labelled input on the breakout board. All my inputs use a 0.187" cherry microswitch, so I've been using 0.187" quick disconnects. However - I'm not too sure what's the best method for actually daisy chaining, since you'd need two connections to each ground pin. I've seen a few splitters for quick disconnects, but they're nearly all 0.25" which doesn't work for me. I'd prefer not to solder, since this is a first try and I figure it's easier to have it be modular in case I mess up. Any parts recommendations would definitely be appreciated, since I seem to not be able to track one down. I've also seen people talk about a ground bus, which could work, but I wasn't sure if I'm overthinking it.
Also, may be obvious, but: if I'm daisy chaining, I assume I'll daisy chain each ground pin on the stick, then daisy chain that to the individual buttons?
Thanks for your help!
