Personally, I don't give a shit about any of these proto games. To me they were unfinished and unreleased for a reason. I do respect the energy and financial commitment required to release them, however, and understand the historical side of things to see an interest in these products. They just aren't for me. I like my neo games to be completed.
You are 100% entitled to your opinion. And you are also not alone. Many others in the community feel the same way you do. However, I would like to correct some of your comments to ensure that the community knows the facts and the track record when it comes to the neogeo proto games that have been discovered so far.
Yes, often times unreleased prototype games that are found are either incomplete, buggy & full of glitches, and also in some cases of less quality then what a released game would have been. But, released games can also have glitches & bugs and can also be of less then stellar quality. The most significant neogeo examples that I can think of would be Legend of Success Joe & Fight Fever. Have you played these "complete" & "released" games? They literally "feel" like protos. Some of the sprites are unpolished, the collision detection is horrible, and the frames of animation are well below what would be acceptable! And these games were considered to be "complete" and were officially "released".
Secondly, and this is the point I REALLY want to make to ensure that everyone here is correctly informed. I have dozens of protos for the other consoles such as Atari, Sega, & Nintendo, where prototypes have surfaced that are "incomplete". But NOT on the NEOGEO! ABSOLUTELY NOT on the neogeo. For the record, with the ONLY exception of Treasure of the Caribbean, so far every single neogeo proto that has come to the surface has been complete. Bugs? Yes, sure, but as I mentioned, even released games on all the systems since the dawn of programming have bugs. But so far as being a "complete" and "functional" game, so far the neogeo protos have indeed been just that. Zupapa, Ghostlop, Ironclad, Bang Busters, etc.
So by all means, I do not expect you or anyone else for that matter to have to love and support the neogeo proto scene, and yes, most of these games did not see a release because they failed location tests and/or were not economically viable. And yes as well, they can have bugs, just like any released games do. BUT, to "assume" them to be "incomplete" or "unfinished", is incorrect. I would even go so far as to say that of the remaining ones that we know about that really do exist as protos, they are all complete and fully playable. PLEASE do not let the isolated incident of what happened with Caribbean (call it a bad apple) ruin the entire bushel of apples that remain.
