I bought this hack for my husband as a gift. He really enjoyed it and said it was very challenging but it was not the hack we were expecting, where you can steal a trainer's Pokemon after defeating them. After doing some research we found out there are multiple team rocket hacks, and the one we expected is hacked from the red version, and this one is blue. The description on this site says, "This is a custom made game and is a hack of Pokemon Red" but that is not accurate. The picture of the item is correct, showing the blue cartridge, and I overlooked this detail when I bought it. So overall he enjoyed the game and I was happy with the purchasing/shipping but just disappointed we couldn't steal Pokemon! lol
