I'm not counting those out anymore - on the emulation front - Couriersud added a better simulation of "Pong" to MAME very recently, and Adam Bousley of the DICE project is suddenly around again. And gregf is still collecting manuals, schematics, boards, PCB scans, ROM dumps from discrete logic games, etc. I'm calling it now: a new wave of TTL-based game boards being simulated within the next five-ten years, so we're gonna need all the information we can collect, including physical PCBs.
