I couldn't believe my eyes, when I just checked current Humble Bundle offers and saw this Neo Geo special there:

Of course, these are just ports to other platforms (even browsers as it seems), so no "real deal". There are also soundtracks.

But needing to pay just $10 for all of them and giving some of that to charities doesn't sound too bad I think.

Not the first time they do that.
I got two tshirts from two previous SNK bundles this way.

You're right, that's a great way to support what's left of SNK and charity.

It's a repeat of a Bundle done a few months ago. Exactely the same titles, emulated by DotEmu.
