I have made a one-handed sega genesis controler. And IT WORKS TOO!! I call it the G-MOTE. It took me four hours to make it. It costed me $14 in all to make it. I had to buy a soldering iron and solder. The rest was free.
Here are some picture of the G-MOTE:
A G-Mote huh? Now isn’t that one of the most creative stuff I have ever seen in my life. What makes it even more cool is the fact that you made it yourself. I think if I tried it, it might take me a while to get used to it. Really cool Nightwheel.
Edna: Eh, you will be very surprised. In fact, I know many people who play portable game systems like a GBA with one hand. Kinda crazy and kinda hard, but imagine what you can do with your other hand. You can eat/drink and play at the same time!
