I'm glad that masses are appreciating this classic, It took me nearly 10 years to track down all of the parts for mine. It's pretty easy to do with original hardware and donor sente carts with a rom burner, cool that you are reproducing the boards, are you also making the 14 slot carts ? Are they going to be 1:1 or are you making custom SENTE Multi board?! Are you also planning on reproducing the main sente motherboards ?! Doesn't make much sense for the hardware as virtually none of the control panels are compatible.
Speaking of control panel, are you Silk / UV printing directly to metal just like they did back in the day ? or are you simply using a 3m / similar type control panel overlay ?!
However to those of you that wish to view this thread and do it on your own :

To those that wish to create your own harness this will help you:
Also I have yet to dump the prototype Chicken Shift roms which DON'T exist in MAME.
A while ago member GackAttack made the repro control panels for chicken shift I think another member also hinted or did it as well, pretty easy.
The Chicken Shift Marquee was scanned in from Gregafree game with help from animesuperj , I think Nesjess (*not sure about the klov spelling / handle) traced it ?
At one point I had a thread going with virtually all of the Sente Art shared:
