I realize that the seller states it's a "homebrew" but it's not, it's a copy. And look at how many...
And I'm seeing this more and more. I specialize in Atari 8-bit carts but see it bleeding over.
Individuals are printing boxes, instructions, and cart labels with the intent to make them look as close or identical as possible.
Yes some are easily identified, but others are not.
Then years from now they'll circulate as originals.
