Not really shocking given the level of bitch around here, but I find it amusing that you're the only person asking real questions.
This is some of the most lazy, low effort shit in gaming. These crappy emulator repackages should be like $5 max.
You could do a lot of really interesting stuff with a proper remaster of the Samurai Shodown games like make the games render at double resolution so that even when you're zoomed out the sprites still look just as detailed as they do when you're zoomed in, etc. That would actually require effort and cost money, though, and they know that stupid fanboys will pay for literally anything with the name SNK on the box, so they squat out these turds.
