what?? they are? I got another workin one upstairs, there was this junk market last weekend where people sell there junk... so toys, furniture etc etc... I found my own NES there like a year ago, bought one for 20 euros, didnt work BUT, it had 2 workin controllers and a zapper + the original box and booklets etc etc + about 10 games... even the foam... so I went back to the junk sell a little depressed for my NES not workin (the cable that attaches the screen an NES was also missing , used teh one from my SNES, but showed that the NES itself was broken...just kept blinking from white to black screen, no matter what you did)
then there was another one, without box, and few more games and again 2 controllers, all cables, AND a zapper...5 euros all together... bought it...worked perfectly :cheers
So I used one of them zappers for my sidearm... now this year, I must have come across 8 of these zappers all sold by different people, most people had 2 of em.. now I dont know if they all worked, but the most expensive 1 was 2,50 euros..
In A'dam there is this gaming shop, specialised in old consoles, like old sega's, atari's an old NES, SNES & N64, where they also sell these zappers, for about 6.50 euros... not that expensive...
