Before I got a real pin I was seriously thinking about building one as I use Hyperspin in my arcade cab and am an active member of the forum....or was until I got my pin

Now though, for the money it would cost, I don't think I'd bother. To get a nice one built without any lag or other software issues you'd need a pretty hefty
PC and when you add that to the cost of the screens it would be a fair wedge of cash.
I've seen vids of people who have them in with a collection of real pins and that might be better although even then would it get played if you had real pins?
Don't get me wrong I think Hyperspin is amazing and if you've got a MAME cab then it's a must

Just not sure about virtual pin cabs anymore.
