First post; hi, everyone.

Getting down to business, I'd like to know whether or not anyone's ever dealt with THIS WEBSITE before? It seems professional enough, but it would be nice to get some confirmation. If not, any links to other (cheaper) converters would be appreciated as well.

I've never dealt with them before, BUT before you go running out buying one of the converters- you might have one in your collection already. You see, Nintendo's first round of shipments of games ALL contained converters. Here's how to tell if you have one in one of your games.

1. The cartridge must be a "black box" cartridge. (Gyromite seems to usually contain a converter, and EVERY copy of Stack-Em-Up ever made contains a converter, but I wouldn't ruin a copy of stack-em-up just for a converter.)
2. Look on the back of the cartridge. If it has 5 screws, there's a chance it will contain a converter.
3. Now the final step- if your cartridge meets the last two criteria - get into a place with a good light source and look at the part of the cartridge that connects into the 72-pin connector in the Nintendo. You will see a row of little copper pieces along the board. Each of these copper pieces has a small knob at the bottom. If the knob is centered on the copper piece, you don't have a converter. But IF the knob is off to the side of the copper piece, YOU HAVE A CONVERTER IN YOUR CARTRIDGE!

Hope this helps.

The Gyromite style converter does the opposite of the one in the link.

You're right, KevinLG.
I don't click links in forums, so I just assumed it was the one to play famicom on NES, not the other way around.
Whoops... But what I said still stands!

believe that site has an ebay store, if I remember correctly. Also, I think the store had good feedback.

Thanks for the replies; I'll be using this converter to save time and energy...and solder.
