No, I'm not a dev, simply another player that does like to mess with things to make them work in the weirdest places since I got a PSP.
That said, also no, the BIN file is a genesis/mega drive ROM because this game was originally made to be able to run on the system. Just like Pier Solar has a genesis compatible version.
About the missing library not being included with the game itself, I believe it's a thing about linux games in general. They MIGHT install additional libraries for you, (specially if it's steam stuff) but more often than not, they won't. When they don't work, you need to check for log or launch them from a terminal to know what kind of error it spits out, find out how to install what it needs, restart if necessary and try again. It shouldn't be as tiring as "missing .xna package, install from microsoft site" but it feels more tedious or like it is extra work because we're likely not used to it.
I get what you mean about "don't get extra packages unless you trust them" but I personally don't mind it much. I've used way too many sketchy software in windows to be worried about everything I'm getting on linux. I dunno, it just feels safer?
