Today I had some free time on my hands so I ended up watching gamesack (the 'tude sack episode makes me laugh so much)... Anyway I got to that episode about Genesis Shoot Em Ups. I got inspired (I'm off tomorrow too) and grabbed all of the genesis shoot-em-ups (roms) from the Genesis Shoot-em-ups episode and copied them into one folder. I watched the episode again but paused it to play all of the games they were talking about in sequence. It was a cool way to make sense of all the roms and emulators I have. I had a Sega Genesis as a kid and side scrolling shooters were my favorite genre. Air Busters is a freaking classic. I'm playing it right now.
Anyway, in said gamesack episode, they cover every shooter on the Megadrive/Genesis platform. A lot of the games they cover, I had never heard about. But sure as shit, I have the rom of every damned game in that episode. F.Y.I. I leave out everything that is not a vertical or horizontal shooter. That "going into the screen" crap (Space Harrier, Afterburner) doesn't count.
