John's personal arcade website and home of the unofficial Nintendo Vs. Tech page. You'll find all you'll need to know about the Vs. System including a game list, PPU and chip compatibility, instruction manuals, dip switch settings, etc. You'll also find videos of most of the Vs. games he owns. A valuable resource!
Although it's mainly a Playchoice-10 site, there's a great section that has info and artwork references for many of the Vs. titles.
Excellent resource for arcade flyers. The link above goes directly to the Nintendo Vs. flyers that they have in their database.
