Playability of Quattro NES games?

[sidnotcrazy]

Also, what's the deal with the switch on the back of the carts? I know that some of the Codemasters games were supposed to fire a voltage spike through the NES10 chip or something, so is that what that's for or is it for something else? I'm using a Messiah NEX system right now since my NES is in storage, and I'm hoping these Camerica carts aren't going to cause it to malfunction...

I never heard of the switch firing a voltage spike before. What I have read on the subject is the switch is there to allow the cartridge to work on a NTSC Nes, or a Pal Nes. So they would only have to manufacture one type of cart. Speaking from personal experience, I have played Camerica games on my top loader, and had no problems whatsoever. However, I have run into some models of the Nes that won’t play them simply due to lockouts.

About the Quattro games, I have yet to play them.
