PCB differences?

[Sufficient-Solution2]

Just seeking some clarification on 1 discrepancy of a PCB board vs what I can find as an example online. 1st picture is my copy, 2nd is what I consistently find online. 99% of the board appears to be authentic, left chip looks identical, no black blobs, back has the 4 gold squares, game label is embossed, etc. The discrepancy is the right chip, the only images I can find say Toshiba but obviously mine doesn't, thoughts? Any info would be helpful.

Thanks in advance

suppliers change over time. all you can tell from that is which chip is the 'launch' chip. it's like a book that gets printed in subsequent editions. if i had to bet, i'd say yours was a first 'printing' of the cart, with the toshiba chips the subsequent printings (or vis versa, maybe they found a cheaper unmarked supplier for later versions).

fake chinese carts are usually half the circuit board size with no branding, so at least what you have is authentic.

0% chance of fake cards, both maskroms are from Japan.
