This is the short thread that was talking about it:
I mean, it looks like an amazing project and all the hard work is paying off, my main interest is really about using it in a jamma cab, PCB prices are getting too intense and it's just no fun anymore, and with hardware becoming fickle with time, maybe the time has come to invest in a setup.
I was just thinking that maybe there are still some small issues left to be sorted out. I was just surprised to see posts about speed difference, considering how much I had read about the accuracy of fpgs setups in the past.
This is not a diss against the project, at all. It's very impressive!
