David,
You must be forgetting about the Aero Fighters 3 MVS cartridge then.....
I'm stating all facts. No, I cannot prove 'LN' is you, nor do I NEED to. The situation, as a whole, looks mighty suspicious when you assemble all of the tidbits of information that have been exposed. I simply mentioned the odds of two people within the same vicinity buying the same cart at almost the same time while all of this other stuff is going down is mighty slim. I've stated from the start that things surrounding these releases (AF3 & PS2) look fishy.
As for the PS2 kit; you are of course free to do as you please with it, it's your property. I'm not doubting for a second that you still have it in your possession; I have kit boxes/artwork from over a decade ago. But nothing could have stopped you from pulling the game boards out of the cartridge shell for a certain project and replacing them later with another copy of the game. We all know the boards/chips themselves are not unique/serialized, so your stance is moot.
To be honest, I would love to find out that these are legit; it would be nice for more 'missing relics' to be uncovered about SNK. While most of what I've been writing about this fiasco APPEARS to be derogatory, I'm 100% objective/neutral on it. As I've stated already, I have no ill will towards you. I have no problems with you. I like what you're doing (JGP conversion, D-Converter, Memory Card Support, etc) and would deal with you again, without question. I can't speak for others, but I'm going to assume that most of us would be intrigued to hear about the full backstory (and see documented proof) of these two releases.
