Over at 4chan on /vr/ it's full of people who are just discovering and idolizing the TG-16/PCE. It scares me because I worry about prices going up, games getting more scarce.. I liked it better back in the day when my friends made fun of me for having the "loser" system. It was like being in on a secret, though, especially when Dracula X came out in 93 and everybody was mad jealous.
But yeah, about the controller port thing. I had a tap for the TG-16, but when my console stopped working, I got a duo. Of course they decided to change to mini-din then, so it seemed like all my old accessories just had to be rebought. Since I was a kid, I didn't realize you could get converters, so I think I just got rid of my pads, stick and tap somehow (not the only dumb move I made) and I never did get a duo tap. I do want to get one in the future though but I was pretty content playing 1p games.
