Do you believe that a proto should be exclusive to its owner or should its ROM be "freed" so that everyone may enjoy the game?
This is a controversial subject. And I apologize in advance, but my answer will be very long! But I do have a very good explanation for why both schools of thought can be seen as correct, so I think it will be worth your time to read it. I truly believe that if the community had the same perspective on the subject, we would all benefit from it.
The first issue is that, in reality, anyone who has a proto is not technically the owner of that proto. They may in many cases be the legitimate owners of the actual physical proto cartridge itself, but not of the actual rom data contained on the eproms. The programmers and/or the companies that they were employed under are the true owners. However, in most cases the companies are out of business and the programmers cannot be located.
The second issue is in regards to how the owner obtained the proto. We all know that these protos are extremely hard to find and/or are extremely expensive to buy from whoever is found to be holding them. We have also seen that they lose their perceived value once the games rom data has been dumped and has been made publically available.
So a proto holder loses his games value and his games trade ability when he decides to share it with the community, but he gains the praise and appreciation of the community. However, a proto holder who keeps the game locked away and unavailable maintains its elusiveness and high end trade value, but he is ridiculed in the community and is called a "rom whore" (rom hoarder)
Usually, when a proto is found in the wild, or is in possession of a casual collector, it will eventually find its' way to being released. The reason for this being that money becomes the motivating factor for the owner and the community eventually provides it.
The problem is when a proto happens to be in the hands of a high end collector. Since money is NOT a motivating factor for them, the only approach is a trade. In addition, trading with a high end collector is at the absolute highest level. It is not something that can be negotiated easily because you have to bring to the table something that they do not have! In most cases, the only thing that qualifies is the same thing they have, an unreleased proto! So trading protos is a high stakes poker game which not everybody can play.
Why do you think there are collectors who still defend the idea that there should be no sharing?
It is usually a split right down the middle. It is easy for those who do not have any time or money invested into tracking down & acquiring a proto to demand that it be given to the community for free. They have no understanding or appreciation for the personal & financial loss that the collector suffers as a result.
In the Atari, Sega, & Nintendo communities, we have what are called "controlled community releases" The collector is compensated for his game through a direct initial payment which is paid for by making a small production run of cartridges which are sold at a cost per unit that offsets the cost of buying the rom data and/or the proto cartridge from the owner.
However, much like a collector with a rare coin, painting, or manuscript, owning a one of a kind game that no one else in the world has can be quite a thrill and give a sense of euphoria. It has the power to manipulate your thinking. Allow me to share from my personal experience.
In February of 2003, I acquired my first NEOGEO proto game, Ghost Lop. At the time, I was very naïve and inexperienced. I had spent quite a bit of money to buy the game, and I was anxious to recuperate it. While I enjoyed some of the attention, I was nonetheless foolish. I was manipulated and rushed into making a bad trade decision with the game, and as a result Ghost Lop lost its' status as a high end trade. Immediately after this all happened, I promised myself that I would never again make the same mistake with the next one that I acquired. So specifically in regards to NEOGEO protos, my policy is a trade-only policy. They are not for sale, not at any price. Only an even exchange with another high end collector for another unreleased proto will even qualify.
Sadly, the only way that they will ever see the light of day, will be when all 172 numbers are 100% accounted for. And the only way that they will ever be dumped or released, will be when the other holders do the same. It is a stalemate. A Mexican standoff!
