Back in the early 90s, Sony and Nintendo experimented with adding a CD drive to the Super Nintendo. They even went as far as making a functioning prototype. Well, it was functioning at the time, but now hardware hacker and tinkerer Ben Heck has made it work again.
A new episode of his show goes into detail about how the console works, taking it apart, testing all the chips, replacing the capacitors, and finally, getting the console to work.
The SNES PlayStation is one of gaming’s biggest “what if?”. Nintendo rejected Sony’s idea for a CD-ROM based, and Sony then went on to make their own CD-based console: the PlayStation. And the rest is history.
