will you please give me a link for a list of all Konami games with screen shots ?
There exists no such link. If you want a magic list, you'll have to make one. However, you can find out what konami games were available by browsing auction sites, or checking out the famicom world games list and seeing how many there are. Problem being that there are other game publishers games, and in addition the list is incomplete. The best way would be to purcahse the book Family Computer 1983-1994 by the Tokyo Metropolitan Museum of Photography, but that is a 40 dollar book.
That book doesn't have screenshots. And it'll be hard to find screenshots for all Konami games. Try emulation. You can play the games and get your own screenshots.
True, but it has a (nearly) complete list.
It's got errors. :P And our licensed games lists are more complete, by far. We've also got a bunch of pirate originals and some significant hacks on our lists.
It's also worth noting that if you're looking for NES (US and EU) games as well, you need to include games by Ultra and Palcom.
(OT: Is the Famicom game list on wikipedia taken from FW's game list?)
The FW lists are taken from the book mentioned above, the Wikipedia list, and many of the actual games (carts, disks, title screens, etc.). I promise it's the most accurate list, and much more accurate and full than the Wikipedia list. If anything, these days contributors to Wikipedia's lists would be stealing info from our lists. :P
