@Audiofreak has a site here which lists most of the projects which have real pin files available, along with form(s) for contacting the authors - that will go straight to their email inbox instead of through VPUniverse (can anyone else reliably access VPU? I get gateway errors every other click, I haven't been able to log in for weeks) -
https://pin-display.ch/
Alternatively,
@dzorbas has also got a site listing real pin projects and links to either the VPU forum thread for contacting authors with donations or to the download link if donations aren't required -
https://sites.google.com/view/pin2dmd/colour-files.
I think both sites are reasonably up to date, though it looks like there has been significant activity in the colouring scene in the last few weeks, so if you are looking for a machine that isn't listed on either site, VPUniverse "PIN2DMD works in progress" forum is the place to ask. I will add that if anyone is trying to get any of my projects through VPU but can't log in then drop me a PM and I can send them through here.
