I was aware that some NES boxes have both oval and circle seal variations, but I didn't know it occurred on carts too until just recently. I saw that Mega Man can be found with either a circle or oval seal on the label so I got to looking through my carts and I noticed that my copy of Mario Bros (the original) has an oval seal. I checked eBay and I noticed that it can be found with both a circle and oval seal as well. Is there a list anywhere of NES carts that can be found with both seal variations?

It gets worst, manuals too! Also, some manuals have a star next to the nes code. Oh, and some seals are TM and others are (r), also there are Rev-A games and non rev an...I think legend of zelda has one of each of these.

and don't get Jose started on the CAN stuff too.........................

I think RF Generation has the only list I've found to have with the seals noted. Otherwise NGD's list is the most comprehensive.

Can you post links to them? I'd appreciate it!

Edit: Looks like you have to choose "NES" and "North America" each time you click the RF link for the actual list.

Technically the seal on the cart should match the cart, box and manual. Another thing to consider when CIB piecing together

There are so many to name today in the mail I received my black Rad Racer Manual, another classic example of variations.
