WATA certification

Certification Number: 595776-014

Analysis: Frank Cifaldi

Object Analysis:

Object is a bare circuit board displaying part number SHVC-2P3B-01, a known Nintendo-supplied prototyping part. The board appears authentic, and the IC chips have manufacturing dates appropriate to the game's development period. Typewritten stickers on the two data EPROMs denote the game's manufacturer, title, and numerical order.

Data Analysis:

CRC-32 (Ethernet and PKZIP): C577AE88

SHA-1: C495F5A31B260A2BC3197870514C61B0B7C2A497

The data differs from the retail game, and does not match any known data available online. Observable differences include a longer load time after the game is powered on, as well as differing enemy formations. Both of these differences are present in the original Japanese release of the game, which preceded this U.S. version. Effectively, this game appears as the Japanese version of the game, but with U.S. copyright info on the title screen.

Provenance Notes:

According to the submitter, this item was purchased from the McLaren Auction Services "Vintage Nintendo Online-Only Auction," which ran from March 25 to April 1, 2022. McLaren claims that these items came from Steve McKay, former "General Manager of the Mexico Division" at Nintendo. Approximately 97 items from this auction were submitted to WATA at once. Given that the auction listings are not archived on McLaren's website, I was unable to verify each individual item as having come from the auction. However, I did view this auction when it was live, and can attest that the scope of this collection is in line with my memory of what was available.

Conclusion:

Given the authentic parts used, the provenance, and the unique data available across the items from this McLaren auction, I have no reason to doubt the authenticity of this item.
