No Way, look at the other games he is selling. Cosmo fighter 2, winky trap, kill barney. If he is truly clueless then he bought these from someone that made their own carts from roms and he should be told that he should make sure to declare that these are not authentic and that they are re created from rom. If he didn't buy these from someone else then he is outright lying to you and made them himself.
Daniel never gave his games out with just a white sticker on them and the stickers look similar to other games which are all done by different people.
half those stickers are not even in the sticker location and are at the top of the cart which no homebrewer would. I have these homebrews they are all beautifully labeled.
Look at his common games he is selling that he calls rare, the parker brothers games are in coleco carts. These are basically all fakes. He either got screwed from a seller that made all these games or his is making them himself. Tomarc the barbarian is in a coleco cart. Give me a break. All his auctions are crap.
