HELP! NES Donkey Kong vs Donkey Kong Classics Question

[Draugr]

Hi,

I was wondering if anyone can tell me if there is a difference between the NES "The Original - Donkey Kong - Arcade lassic Series" Cart and the version of Donkey Kong on the Donkey Kong Classics Cart.

I recently bought both through a vendor and was told that they were different. Unfortunately, I just ordered and received a Game Axe (Portable NES clone). I had to send it back because the LCD screen didn't go on, but the unit worked when plugged into the TV. Anyhow, I decided to download the ROMs of both the above games and when I played them on the Emu, it looked exactly the same. Can anyone please clear this up for me.

 

Thanks

 

P.S: I thought there was a DK cart that had ALL 3 DK games on one cart. Does that exist and if so, hat is it called.
