@ Gezo, Let me try working on the type on the background, to see if I can change what is says. (Since it still says Saitama~ instead, and maybe a small modification to the don-kat chitai to match Mata's chart.)
@Ono, A little late, but those HQ captures are taken because those players have access to (which means own) a Namco 256 PCB and the AC14 CD (and a bunch of other needed parts such as a security dongle, i/o board, etc.). After that, it's almost the exact same process as taking HQ captures of console games. The main problem there is it's quite difficult to find those things, especially when you're out of the country. (There are physical stores in Japan that sell pretty much nothing but arcade parts, such as the ones I mentioned.)
Why do I always have tp be asleep when you guys are awake. I always feel like I'm late to the conversation. Stupid time zones. :p
