Which Plug N Play games feature NOACs?

[iamtyler]

The other day I bought a 25 in 1 plug n play game system in hopes that it had a noac in it.. I was googling noacs and one place said that many x in one game systems feature noacs. Well i took it apart and peaked about at the guts to see that it didnt seem to have a noac chip... But then again i wasnt sure exactly what i was looking either.
So my question is simple: how do you tell if a plug n play system features a noac? I know you can usually tell if the game is a nes game... But what about systems that dont feature NES or SNES games? And what would a noac look like?
All help is apreciated

Look for ones that play NES games.

Although I wouldn't put it so bluntly.

Meant to say cartridges, since most would have cart slots.

just get a Yobo FC. It can be found for like $12 and there's no mods that need to be done to make it play carts. Compatibility is pretty good as well.
