I had pretty good luck reaching out to the developers on Discord these past couple weeks. Not sure when you tried but I recommend trying it again. I personally I think snips is way more appropriate on something embedded like a RPi. I was up and running with their new sam package within minutes. Their new update (about two months?) really made it more user friendly. Unfortunately, their windows packages is still very broken.
E: You should probably try in the late night or early morning time for the States (EST) since they are located in Europe I believe.
I'm currently running snips on a RPi 2 (Model B) and it's working so far so good! Not too sure about the original Rpi though. I'm debating on getting a RPi 3 to see if the performance is better.
