We’re talking about graphics from a few decades ago here, so it’s not going to be cutting edge stuff. That being said, these games do look clean, and they are colorful. Arcades were still the best looking, best sounding gaming out there for the time, before consoles starting surpassing them in power. The Cabinet gives you options for tweaking all of it to get the experience you want. You can adjust the graphics settings to smooth out things, for example. This kind of emulates the old school CRT monitors the games would have been displayed on back in the day. Whereas you can display the image cleanly on a high resolution monitor now, and show every sharp corner of every pixel, back in the day the monitors blurred everything a bit. It almost made up for some of the graphical limitations of the day in a way, since it could round out edges and blend colors where those things weren’t really possible in the games themselves. You can also enable a mode that adds the scanlines some monitors had. These are some pretty cool options for emulating the experience from way back when.
If we’re comparing games in the first game pack here, I wouldn’t say any of them really outshined the others in terms of look and sound. They simply approached graphical limitations in different ways. Avengers is an overhead scrolling beat-em-up with chunky sprites for the players and enemies. The background music is actually pretty good for its time, reminiscent of the background music from action movies of the same time period. 1943: The Battle of Midway is colorful, taking you over oceans and green plains, though most of the planes are similarly colored to cut down on the total number of colors. There’s a whole lot of repetitive sounds from your guns and the enemies, so the background music doesn’t really stand out. Black Tiger uses the black backgrounds trick to keep the overall colors and details down while keeping the feeling that you’re in a cavernous dungeon. A pretty standard adventuring track plays in the background. I really can’t describe the genre this music comes from other than to say it sounds like the music from a lot of similar fantasy adventuring games of the time with that chiptune charm to it.
