with my nes i put my game in switch it on but it comes up with all green and purple lines and i cant play my games some1 help

Dusty Cart. 'Nuff said.

Clean your cart with a q tip and some rubbing alchohol. and if that dont work, buy a new 72 pin connector.

soz but wat is a cart??

Dont ever say "soz" again. A Cart is a Cartridge, you know that grey thing you put in to play games?

And try to use atleast some form of proper punctuation and grammar.

I second that.

ok i have cleaned it and it is working but i still have green bars on the screen while im playin any ideas?

Open up your nes and clean the connection between the motherboard and the 72 pin connector (Works like a charm for me), but if the lines arent that severe just move the cart ever so slightly to the left or right until the lines dissapear. Also just try cleaning the game again, maybe you didn't get all the grime on the first go through

Good luck!
