Yeah some have converters in them, i don't have a list of the 5-screws but i'm sure NGD has a list for ya.

I remeber reading something about it now when you speak off it. I'll look into it.
On the topic, are there any 5 screws that are rare or are all common games like Gradius and the black series?

I think there's generally a lot more challenge in finding the hangtab box that goes with the five screw game than of finding the game itself..

If you take a look at the FC to NES adapter thread on this page, there is a link posted with a fool proof way of finding the adapter without having to guess (the shape of the pins).  Found one in an excite bike cart myself.  I don't use it however, I have a honey bee adapter I find to work much better, and they cost less than $10 usually.

Wow, gongrats bro! I'd probably shit myself if I was able to come across one. Every 5 screw I've taken apart had the converter already ripped from them 

Enjoy.

I think they are harder to find than most people think.  I check every cart (that could possibly have a converter) that comes through my hands.  Aside from Stack Up, which all have converters, I have only had one Gyromite cart with a converter.  I have had many 1000's of carts come through me.  Maybe it's bad luck, my area, or something else, all I know is I am looking to find these varients and they're tough to find in the wild.

I have never had any problems finding them at all.  I was looking for some a while back and went to a flea market.  In one day I got like 10 of them and didn't even search through all the guys games.  Another time I bought out a local collector and almost every game he had had one in it, his parents bought his games the day they came out back then so he had orignal copies of every game that first came out.  Maybe it is regional like Michiganfan mentioned, that or I am lucky.
