Zip files would by far be the best outcome. Then people could do as they please -- put it on a flash cart, mister, or make their own cart from bootlegs. We don't need another overpriced cart "release" like with Ghostlop.
When I say that each and every unreleased game released was done with a butt - I mean it. Every one.
If I am the one to release those games, it will be not only 101% conform to genuine games, but also at the same price as they were back then. I'm starting up a car business with the sole objective to buy these games and release them, and I don't give the lightest care about making money or losing money in the operation. I would have taken a 50k loan or more to buy that game from the Japanese guy.
I just want it done, and done as it should be. In the end, every game from NAM-1975 to Samurai Shodown V Perfect was dumped, and emulated. And I want it to be the same thing with the unreleased games. I don't want everyone to just download the ROMs and play it on MAME for 5 minutes. Back then, a game was dumped by some guy, on his desk. Buying the game at the local shop, taking the seal off the side of the case, playing it for hours, then taking the PCBs out of the cart shell, with the NGH-marked chips off of machine-soldered, SNK-silkscreen boards, desoldering them, putting the chips into his ROM reader, dumping them, sharing them on the Internet and feeling a bit proud for sharing some good games. All I want is guys to be able to do that. Simply, to feel like they did back then. One last time.
Not like Ghostlop. Not like B²B. Not like TotC. Not even like !Arcade! releases.
Like SNK.
